Complete existing Android (Kotlin) app to match React Native app
Overview We have an existing multi-module Android Kotlin project that is partially implemented. We also have a working React Native app that represents the “source of truth” for features and user flows. We need an experienced Android developer to finish the Android app to match the React Native version (UI/UX + functionality + API integration), and deliver a production-ready build. What you’ll do • Review the existing Android codebase and the React Native app to understand required flows and screens. • Implement missing Android screens, business logic, and networking to reach full feature parity with React Native. • Integrate with existing backend APIs (authentication, catalog, cart, orders/checkout, profile, etc. as per RN app). • Ensure consistent UX behavior with RN: validations, error states, loading states, empty states, navigation, and edge cases. • Fix bugs, crashes, and performance issues found during implementation. • Add/complete unit tests where appropriate and basic UI tests for critical flows (as agreed). • Prepare release builds and ensure the app is stable on common Android devices/versions. Scope / expected parity areas (examples) (These must match the React Native app behavior.) • Auth: login/register, logout, token/session handling, refresh, forgot password (if present) • Startup flow: splash/startup checks, session restore, routing • Home/Catalog: categories, product list, product details, search/filter/sort (if present) • Cart: add/remove/update qty, totals, promo codes (if present) • Checkout/Orders: address, payment method flow (if applicable), place order, order history/status • Profile: user info, addresses, settings • Networking: consistent API models, error mapping, retries/timeouts as needed • State/UI: consistent loaders, toasts/snackbars, offline/empty handling Tech requirements • Strong experience with Android Kotlin (production apps) • Modern Android stack: Coroutines/Flow, Retrofit/OkHttp, Jetpack (Navigation, ViewModel), Room (if used), Material UI • Familiar with DI (Hilt/Dagger/Koin) and clean architecture patterns • Ability to read React Native code to mirror flows/logic (no need to write RN) • Solid debugging, code quality, and testing mindset Deliverables • Completed Android app achieving feature parity with the React Native app • Clean, maintainable code (consistent style, no hardcoded secrets, proper error handling) • Working builds: • Debug APK • Release AAB/APK (as required) • Short setup/build documentation (README update): environment, build steps, signing (if applicable) • A checklist of implemented features + any known limitations Acceptance criteria (how we’ll verify) • All major user journeys match the React Native app (screen-by-screen and behavior). • No crashes in standard flows; critical bugs resolved. • API calls match backend expectations; auth/session works reliably. • App builds successfully on a clean machine using documented steps. Engagement details • Start: ASAP • Timeline: propose an estimate after initial review (typically 2–6 weeks depending on gaps) • Communication: daily/regular updates with progress + blockers • Work style: milestone-based delivery (recommended) To apply, please include • 2–3 relevant Android apps/projects you’ve shipped • Your suggested architecture/approach for achieving RN parity efficiently • Estimated timeline and cost (milestones) • Any risks you foresee after a quick repo review What we will provide • Android Kotlin repository + React Native repository • API base URLs / environments + test accounts • Any UI references (screenshots/videos) if needed

Therefore the following experience is necessary **Key Responsibilities:** - Develop new features and enhance existing functionality for our directory website using the MERN stack (MongoDB, Express.js, React.js, Node.js, Next.js). - Utilise trunk-based development practices to ensure smooth and timely integration of code into the main branch. - Work collaboratively with other developers to resolve conflicts and merge changes efficiently. - Perform regular performance and bug-fixing tasks to ensure optimal website performance. - Write clean, maintainable, and efficient code, following best practices and industry standards. - Participate in code reviews to maintain code quality and provide constructive feedback. - Continuously improve and upgrade the software to keep up with the latest advancements in technology. **Required Skills and Experience:** - Proven experience as a MERN Stack Developer. - Strong understanding of trunk-based development and its best practices. - Prior experience working in an agile environment with regular sprints. - Proficiency in MongoDB, Express.js, React.js, and Node.js. - MUST MUST be proficient with Docker and build architectures. - Familiarity with version control systems, particularly Github and Github Actions. - Excellent problem-solving skills and attention to detail. - Strong communication skills and the ability to work collaboratively in a team environment. - Ability to manage multiple tasks and deadlines effectively. **Nice to Have:** - Experience with DevOps practices and tools. - Knowledge of serverless architecture and cloud platforms. - Familiarity with continuous integration and continuous deployment (CI/CD) pipelines. - Typescript experience. If you're after a easy going developer role where there's more work then we can get through then please let me know. No agencies and please only apply if you're used to throwing code out from ticket reference branches - we want to be pushing/building multiple times a day in some situations. Please please please do not apply if you're a junior or mid dev - this requires an individual to undergo a steep learning curve and drive the migration to finalisation. Also - the individual needs to work on the project full time until complete - this is not something that can be done in an hour a day.

I'm looking for someone who can build a solid and reliable prompting framework that delivers measurable ROI for business use cases, not just impressive demos. We need a prompt engineer who thinks like a systems architect, not just someone who can write clever prompts. You'll be designing, testing, and optimizing prompts for production-grade AI workflows. This isn't about getting ChatGPT to write poems; it's about building reliable, scalable prompt chains that solve real business problems. Deliverables What You'll Do: Design and optimize prompts for LLM-powered automation workflows (GPT-4, Claude, open-source models) Build evaluation frameworks to measure prompt performance against business KPIs Develop prompt templates and chains for multi-step reasoning tasks Document prompt engineering patterns and create reusable libraries Collaborate on agentic AI systems using frameworks like LangChain Debug and iterate on prompts when model outputs don't meet specifications Required Skills & Experience: 2+ years hands-on prompt engineering experience (personal projects count if well-documented) Deep understanding of prompt patterns: chain-of-thought, few-shot learning, system prompt architecture, retrieval-augmented generation (RAG) Experience with prompt evaluation and A/B testing methodologies Familiarity with tokenization, context window management, and model-specific quirks Strong technical writing—you can explain complex prompt logic clearly Python proficiency for prompt testing and automation integration Preferred (Not Required): Background in ML/AI fundamentals (understanding of transformers, embeddings, fine-tuning concepts), at least foundational AI/ML understanding, you don't need to train models, but you understand concepts like temperature, context windows, and model limitations. Experience with n8n, Make, or similar automation platforms Exposure to agentic frameworks (LangChain, AutoGPT patterns, function calling) In your application, please begin your cover letter with the word "CONTEXT:" followed by a one-sentence summary of what makes our AI engineering approach different based on this job description. Applications without this will not be reviewed. Assessment Task (Required with Application) Instead of multiple interview rounds, complete this practical assessment: Scenario: A client wants to automate customer support ticket classification. Tickets should be categorized into: Billing, Technical, Feature Request, or Escalation. The model sometimes misclassifies urgent technical issues as "Feature Request." Your task: Write the system prompt you would use Provide 3-5 few-shot examples you'd include Explain your reasoning for structural choices Describe how you would evaluate and iterate on this prompt Time estimate: 30-45 minutes. We value thoughtful reasoning over speed. This task reveals: Do they understand edge cases? Can they structure prompts systematically? Do they think about evaluation? AI-generated responses typically miss the nuanced "why" behind choices. What Success Looks Like Prompts that work reliably at scale, not just in demos Clear documentation that another engineer could pick up Data-driven iteration, not just "try things until it works." To Apply: Submit your assessment response and a brief note on a prompt engineering challenge you've solved. Generic applications will not be reviewed.

Senior Blockchain / Full-Stack Developer Needed to Rescue E-commerce Project We’re building an e-commerce platform that handles global shipping and international orders, but the project is hitting serious roadblocks. The codebase exists, but the system isn’t ready for launch, and our current team is struggling to fix complex issues. We need a senior developer who can step in, understand the existing architecture, and stabilize the platform before we go live. The platform combines a traditional e-commerce flow with blockchain elements. Smart contracts manage payments, tokenized rewards, and some transaction logic, while a Python backend handles order processing, inventory, and shipping coordination. The frontend is built with React.js. Right now, blockchain interactions are inconsistent, some transactions fail, and data between the frontend, backend, and smart contracts isn’t always syncing correctly. This isn’t a new project — it’s about rescuing something that already exists. We need someone with hands-on experience debugging Solidity contracts, resolving state issues, and integrating blockchain reliably with e-commerce systems. You’ll also coordinate fixes across the Python backend and React frontend, ensuring orders, payments, and shipping workflows function correctly. We’re looking for a problem-solver who can take ownership, work independently, and bring a production-ready mindset. If you’ve helped pre-launch blockchain projects get back on track, understand cross-border e-commerce complexities, and can ensure the system is secure, stable, and ready for users, you’re exactly who we need.

ENGAGEMENT TYPE Hourly (Time & Materials) Estimated effort: 22–26 hours total Start: Immediate Level required: Senior / Very Senior Flutter Developer ONLY WHAT THIS JOB IS (READ CAREFULLY) This is a small, precise repair task in an existing Flutter app. There is no greenfield work involved. There will be: No new features No refactors No architecture changes No redesigns No experiments No “suggested improvements” No “I found another bug” unless it can be reproduced locally You are fixing known, clearly scoped issues only. IMPORTANT BACKEND & API CONTEXT (NON-NEGOTIABLE) All APIs and server-side code have been working as late as December 2025. A full Postman collection exists and can be executed at any time to verify API functionality. The backend is Magento 2.4. No backend work is required. No Magento developer work is required. Stripe APIs are live and working. This task is Flutter-only. Any attempt to reframe this as a backend, API, or Magento issue is incorrect. REQUIRED SKILL LEVEL (MANDATORY) You must be: A Senior or Very Senior Flutter developer Comfortable fixing Stripe and Apple Pay issues in production apps Able to read existing code and fix it without rewriting it Able to work independently without supervision If you are not senior, do not apply. NON-NEGOTIABLE ENGINEERING RULE Never update Flutter, packages, or plugins before the existing code is confirmed working. This is a basic rule, yet one that many so-called “senior” developers still get wrong. IMPORTANT CONTEXT (PLEASE READ) The app already compiles. A previous developer requested payment before automated tests were run. That is not acceptable under PPH standards. Testing comes first. Payment comes after. For this reason, the previous contract was terminated. This is shared for clarity so expectations are fully aligned. APPLICATION FILTERS (STRICT) If you present web pages as Flutter references, you are not of interest. If you have no verifiable references, you are not of interest. If you describe yourself as a “full-stack developer”, you are not of interest. If you over-explain, bloat, or try to over-engineer, you are not of interest. I am looking for a specialist, not someone who knows a little about everything. This is a razor-sharp task. Change existing code. Nothing more.
