Optimize and clean up online store
Hi, I have an existing online store and I’m looking for a developer to help clean it up and optimize how it works. The store is live and selling, but over time a lot of small issues, quick fixes, and inefficient solutions have piled up, and now it needs someone experienced to go through it properly and make things more stable and cleaner. This is not about building a store from scratch or doing a redesign. I need hands-on development work: reviewing the current setup, fixing obvious bugs, improving performance where it’s clearly slow or bloated, cleaning up messy or redundant code, and resolving small UX issues caused by poor or rushed implementation. Think things that technically work, but shouldn’t really be done this way. I’m looking for someone who’s comfortable working with existing codebases, understands ecommerce flows (product pages, cart, checkout), and prefers fixing real problems instead of overengineering or rewriting everything. Platform details and access will be shared once we agree on scope and approach. This is a paid task to start, and if it goes well there will be ongoing work maintaining and improving the store over time.

Crypto checkout fails with MetaMask – need testing
Hi. We have a custom crypto payment on our website (not a plugin).

16 days ago12 proposalsRemoteSimple Android OBD-II Diagnostic App
I need an Android application that pairs with an ELM327 Bluetooth OBD-II adapter and performs a very limited set of diagnostic tasks. The goal is to give me a clean, lightweight tool rather than a full-blown scanner. Core behaviour • When the user taps “Connect”, the app must discover and bond with a standard ELM327 device and keep the link alive. • Once connected, it should read live PIDs for engine RPM and battery voltage/status and refresh them smoothly on screen. • A single button should read any stored trouble codes and, when pressed again, clear them. No additional graphs, logging or fuel-consumption features are required. Tech notes I am comfortable with you writing the project in either Kotlin or Java inside Android Studio; please use the standard Bluetooth APIs (or a lightweight library if it speeds development). PID queries can be hard-coded—no dynamic command builder is necessary. The interface can be minimal: two large numeric fields for RPM and battery, plus the read/clear button. Deliverables Full Android Studio project with well-commented source. One signed release APK I can load directly onto my phone. A short README explaining how to pair the adapter and which PIDs you used. Acceptance I will test by pairing the app with my own ELM327 dongle; connection must succeed within 10 seconds, RPM values should update at least twice per second, and clearing codes must return the standard success response. If this sounds straightforward to you, let me know your timeline and any questions you have.

Magento 2 – Fix Ryft Payment Webhooks (Lightweight PHP)
I am running a Magento 2 multi-store environment with a Ryft payment gateway already integrated. The majority of the system is in place, but I need an experienced Magento 2 / payment gateway developer to audit, verify, and correctly finalise the Ryft webhook implementation. This is a senior-level technical task focused on correctness, performance, and reliability. Critical requirement (please read carefully) The Ryft webhook must be handled using a lightweight standalone PHP endpoint. ❌ NOT using Magento bootstrap (app/bootstrap.php) ❌ NOT loading the Magento framework just to receive webhooks ❌ NOT relying on heavy Apache or Magento routing The webhook should be received in plain PHP, validated, deduplicated, and only then pass confirmed data into Magento in a controlled way. The goal is minimal server load, high reliability, and zero duplicate processing. Current situation Magento 2 multi-store setup (many stores, shared codebase) Ryft payments are mostly working Webhooks are unreliable or not firing consistently Some order duplication and inconsistent order state updates Current implementation may be too heavy and loading Magento unnecessarily What I need you to do Review the existing Ryft payment and webhook configuration Verify webhook events are correctly received (eg captured, failed, refunded) Implement or correct a lightweight PHP webhook endpoint Validate webhook signatures securely Ensure idempotent processing (no duplicate order updates if Ryft retries) Ensure correct Magento order state updates once events are confirmed Confirm the final setup is production-safe and correctly architected What I am NOT looking for A full Magento rewrite Magento observers handling webhook ingestion Any solution that loads the Magento framework to receive webhooks Required experience Magento 2 (checkout flow, order states, payment modules) Payment gateway integrations Webhooks, retries, signatures, and idempotency Clean, efficient, production-grade PHP Budget This is a senior task. Fixed budget up to £750, depending on approach and experience. To apply, please answer BOTH questions below: Why is it bad practice to load Magento’s bootstrap when receiving payment webhooks, and what impact does this have on PHP-FPM and server load? How would you design webhook processing to prevent duplicate order updates if Ryft sends the same event more than once? Applications that do not answer both questions will not be considered.

18 days ago46 proposalsRemoteUnreal Engine + Pixel Streaming + Full Platform Integration
We are a technical team and we handle all technical solutions and decisions ourselves. We are not looking for an architect, a planner, or someone else to define the system for us. What we need is an execution-focused engineer who can help implement the website strictly according to our requirements. This project has very strict verification requirements. There are eight platform development contracts based on the same principle; this is just the first one. We need to deliver a multi-role platform based on (state-machine driven + Stripe payments/escrow + ad bidding + 3D digital humans via pixel streaming).Using low-code + modular composition, we are building an international platform. It must be explicitly stated that this is not an MVP. A.Deployment & Infrastructure(Must be assembled and built on the Fly.io platform) 1) The platform must run on (frontend/backend, jobs/queues, WebSocket/WebRTC services as needed). 2) Proper logging/monitoring/alerting is required, including alerts for third-party integration failures and cost/usage anomalies. B.Core Requirements (Important) 1) Multi-role / four portals: end users, service providers, maintenance staff, and admin portal (different permissions and flows). 2) Critical business flows must be implemented using a state machine / state-driven architecture (no “skipping steps”): order → payment → escrow/split → fulfillment → acceptance → settlement → refund/dispute, with full traceability, rollback rules, and audit logs. 3) Payments: Stripe (payments, payouts, webhooks). Must handle idempotency, webhook replay protection, and concurrency-safe state transitions. 4) Automation / orchestration: n8n (or similar) as the workflow hub, connecting Supabase, payments, notifications, ads, and digital humans. 5) Conversational guidance: use Botpress (or similar tools) for conversations + next-step actions. 6) Advertising: creative management + delivery configuration + analytics; ad slot bidding/auction (e.g., Prebid.js / RTB model). Bidding logs must be retained and auditable. 7) Multilingual: UI/content must support multiple languages and integrate language detection and translation APIs. 8) External widgets / external entry systems:iframe / JS SDK / external components with controlled internal core logic. 9) Risk control mechanisms: rate limiting, switches, circuit breakers, fast shutdown without impacting payments) 10) 3D digital human system (Unreal Engine Pixel Streaming): 10.1.) MetaHuman + Unreal Engine for creating 3D digital humans. 10.2.) Pixel Streaming (WebRTC) to stream UE video to web/mobile clients. 10.3.) A unified control interface to switch avatars/actions and drive lip-sync via TTS audio, integrated with state-machine-driven guidance flows. C.Execution responsibility (mandatory) 1) This project must be completed independently by you personally. We do NOT accept teams, outsourcing, temporary staffing, or task splitting. 2) This requirement exists purely for commercial confidentiality reasons. 3) If the project cannot be completed by one individual, please do not proceed. D. Price and maintenance terms (fixed) Project delivery price: USD 3,000 (fixed) Post-launch maintenance: - USD 100 per month (fixed) - Includes system stability, critical bug fixes, security updates, and environment handling - No unilateral price increase is allowed - Any adjustment requires written mutual agreement If your pricing expectation is significantly higher, or if you cannot accept these terms, please do not contact us. E.Delivery time: 1) For an experienced and skilled engineer, under normal circumstances, the full project should be achievable within two months. 2) In addition, we have a clear requirement that within an earlier phase of the timeline, a runnable pilot version must be delivered. This pilot version is not the final completion, but it must already be in a stable, operable state and able to enter trial operation. 3) During the trial operation, we will identify issues, validate stability, and make necessary adjustments, so that the final delivery can meet the required quality standards. F. Please reply with: 1) Similar projects you have delivered (if possible, provide links/demos). 2) Recommended architecture and service decomposition. 3) What materials you need from me to proceed (execution step flows, required module list, etc.). 4)phased timeline, rough price range.
