18 days ago58 proposalsRemoteFinalize Flutter Media App Part-Time Flutter/Node Developer
Global Kirtan App (GKA) is a non-denominational platform for kirtan, sacred sound, and bhakti practice, built for a global audience spanning devotional practitioners, yoga communities, sound healers, and spiritual-but-not-religious users. It's a freemium mobile app combining regular practices, audio/video streaming, a lyrics library with translations, tutorials, event discovery (map + calendar), facilitator and community profiles, and an instrument shop. This isn't a from-scratch build. A working Flutter app already exists with a live backend, and it's been through an independent technical audit — we know its real strengths and its real problems. We're looking for a developer to pick it up from here. The Role This is deliberately not a full-time position, and we can't offer at this time. What we're looking for instead is someone willing to become our standing point of contact for this codebase — available reliably when work comes in, understanding upfront that hours will vary month to month and neither side is committing to fixed employment. If you need guaranteed steady hours, this probably isn't the right fit; if you're comfortable with an ongoing, flexible working relationship and want to be the person who knows this app inside out over time, it might be exactly right. There's no guarantee here — but a developer who proves reliable and becomes a genuine fit for this project would be our first call for full-time or expanded part-time work, once we're actually in a position to offer it. First phase — roughly 20 hours: • Fix the known issues from our existing audit. • Begin work on a new Practice tool — a planned addition to the app's core navigation. Full specification shared once we've agreed terms. After that — ongoing, unpredictable: • Common maintenance tasks • Bug fixes, small feature additions, dependency and security updates, as they come up • Some months will be quiet, others busier — we're looking for someone who can flex with that rather than needing a fixed retainer Compensation Compensation is set at Indian developer market rates. Whether we structure it as hourly or fixed-per-requirement will be decided together based on what makes sense for each piece of work — we're open to either. Confirmed Tech Stack Mobile app (Flutter/Dart): flutter_riverpod (state management), go_router (navigation), dio (networking), just_audio + audio_service (media playback and session handling), youtube_player_iframe (embedded video), flutter_map, flutter_secure_storage (encrypted credential storage). Release builds use R8 obfuscation and are properly signed. Backend (as specified): Node.js + TypeScript modular monolith, PostgreSQL, versioned REST API (/api/v1/), JWT-based authentication. What We Need From You • Real, demonstrable Flutter/Dart experience — ideally including audio or media-heavy apps • Comfort inheriting and working inside an existing codebase, not just building greenfield • Honest communication about your own actual availability — we'd much rather hear "I can only do a few hours some months" upfront than have someone overcommit and go quiet later • A genuine interest in an ongoing relationship with this project, not a single ticket — we're picking a person to grow with the app, not just closing a task • Comfortable working respectfully with devotional and sacred content across multiple traditions • Willingness to sign an NDA and assign IP (Intellectual Property) ownership of delivered work to us How We'll Work • Full Git repository access, normal commit/PR discipline • We'll share our existing independent technical audit with serious applicants (under NDA) so you know exactly what you're inheriting before committing to anything • Payment structure and rate agreed in writing before the first task begins To Apply, Please Share 1. Flutter/mobile projects you've built or maintained, especially anything involving audio/media playback 2. Your honest, realistic read on your own availability over the next 6–12 months 3. Any experience picking up and maintaining someone else's existing codebase (not just building your own)

WooCommerce Experienced Dev needed - Debug Website Issues
Hello, I need an experienced developer to check the website for any incompatibilities, errors, theme problems or plugin issues, and then fully test all the payments methods on our website and look for any bugs or / and theme issues that could be effecting the conversion rate during paying on the website. A few customers have reported issues in the past so an experienced developer who knows how to fully test the checkout and look deeper into logs is required. Note we do not know if there is a specific bug but would like the theme / website checked. Currently use PayPal advanced card payments and Mollie Card payments, some customers are reporting issues with the checkout process. I do not know the specific issue, but it appears to be hesitation on loading screens, or buggy confirmations of successful or failed payments. I can confirm payments are going through but I'd just like to check there are no deeper errors happening server side. Main duties would be 1. Check the website for general issues (If required) 2. Update plugins / themes if needed (If required) 3. Troubleshoot any payment bugs, problems with the checkout process, payment confirmations. (If required) 4. Health check of website, anything that needs addressing. (If required)
23 days ago87 proposalsRemoteAI-Powered Personalized Children’s Storybook Website
Hi, I’m looking for a developer to create a website for personalized children’s books. I already have the books fully designed and illustrated. The AI does not need to create the book or illustrations from scratch. I have already tested the personalization process manually and it works well. The current process is: I have an image containing several poses of the illustrated main character. The customer provides a clear photo of their child. Both images are sent to an AI image editor with a fixed prompt. The AI changes the illustrated character to resemble the child while keeping the same art style, clothes, poses and expressions. I then use the personalized character poses inside the existing book. I will provide you with: the original character pose image a sample child photo the AI result I achieved the exact prompt I currently use ___ What I need initially is very simple: I want a website where a customer can: Choose a book → enter the child’s name → upload their photo → place an order/pay. Behind the scenes, I want the child’s photo and my character-pose image to be automatically sent to an AI image API using my existing prompt, and for the personalized character image to be generated. I also need a simple admin area where I can see: the order child’s name and photo generated character image regenerate it if needed approve the order At first, I do not need the whole book to be generated automatically. My designer can manually place the generated character into the book after I approve it. Later, if the website is successful, I may automate more of the book-production process. The most important first step is simply to automate what I am currently doing manually with AI. Please let me know: if you can integrate an AI image-editing API into the website what AI/API you recommend which platform you recommend for the website approximate cost approximate development time I can send you my current input/output examples so you can clearly see what I need.
