The multi-vendor food-delivery app I already have is live on Android, but it still needs a round of focused development before launch. You will be working on an existing Kotlin/Java codebase (partial documentation is available) to polish the product, fix any blocking issues, and implement the final tweaks I outline once we start. Scope • Review the current repository, understand its architecture, and map the gaps from the partial docs provided. • Implement the agreed-upon improvements—this may include visual refinements, streamlined ordering flow, or additional modules such as payment, real-time tracking, or other features we prioritise together. • Produce clean, well-commented code and a short hand-off note so future maintenance is straightforward. Timeline & Payment Everything must be delivered, tested, and ready for release within 3 calendar days. The total budget is capped at 10 000 INR, payable in full immediately after the final build meets the requirements on my test device. Acceptance A signed-off build (APK) that installs without crashes, passes regression checks on standard Android phones, and reflects all the changes agreed in our kickoff call. Source code and any config files must be handed over through Git or a zipped archive at completion. If you are confident you can dive into an existing Android stack and turn around reliable, production-ready results in three days, let’s do it.

Hi, I’m comfortable taking over an existing Android codebase, understanding the current architecture, and making focused production fixes without unnecessarily rewriting working parts. For this project, I’d first review the repository and partial documentation, identify the actual release blockers, and confirm the exact changes before implementation. I can then focus the 3-day window on the agreed priorities—UI refinements, ordering-flow issues, bugs, or specific modules—followed by regression testing and a clean release APK. I’ll keep the changes maintainable and provide the updated source/config files along with a short handover note. Since the scope is still to be finalized, I’d like to review the current build and repository first so we can confirm that the requested work fits the ₹10,000 budget and 3-day deadline. I’m ready to start immediately.

I can take over the existing Kotlin/Java food-delivery codebase without wasting the 3-day window on a rebuild. Given the deadline, I’d use the first few hours for a repository/build audit and lock the exact change list before implementation, so release-blocking fixes take priority over optional refinements. I’m Sumit Joshi from Sacesta Technologies. My priorities would be clean implementation and user experience. I’m comfortable tracing partially documented Android projects, fixing crashes/navigation/state issues, refining ordering flows, and working with payments, APIs, notifications, and real-time tracking where those integrations already exist or can reasonably fit the agreed scope. A relevant example is JiffyJaf, our food-delivery marketplace work involving customer ordering, provider/operational workflows, backend APIs, payments, and mobile application flows. I can work within the ₹10,000 fixed budget and 3-calendar-day delivery requirement, provided the kickoff scope is frozen after the initial audit. Delivery would include the tested APK, updated source/configuration through Git or archive, regression checks, and a concise handoff note.

Your multi-vendor food-delivery app is live on Android but needs a focused round of polish, bug fixes, and final tweaks. The priority is a crash-free, signed-off APK within three days, with clean handover for easy future maintenance. I would review your Kotlin/Java repository and partial docs to map the architecture and gaps, then work through the agreed improvements in priority order: blocking fixes first, then ordering-flow refinements and visual polish. I would test the signed APK on standard Android phones for crashes and regressions, and hand over clean, commented code with a handover note via Git. Experience: I shipped Jyotish AI, a live Android and web app, so I am comfortable delivering production-ready builds from an existing Android codebase. Two questions: is the repository on Git with a working debug build I can run on day one, and which improvements are must-haves versus nice-to-haves for the three-day window? If this fits, I can start with a quick architecture review to lock the priority list in our kickoff call.

Hi, I am Muheebwa. I understand you have a live multi vendor food delivery app on Android in Kotlin and Java with partial docs, and you need focused work to polish it, fix blocking issues, and add agreed improvements like payment, real time tracking, or a streamlined ordering flow, delivered as a signed APK within 3 days, with source handed over and full payment only after it passes on your test device. What usually matters most here is the 3 day window combined with the open scope, since the real estimate depends on how healthy the existing codebase is, and if the previous developer left broken builds, hardcoded keys, or untracked changes, the first day can go entirely to making it compile before any feature work begins. My approach would be to start with a short review of the repo and the partial docs, confirm what compiles and what is broken, agree a small prioritised list with you on the kickoff call, fix and test those items on real devices, then hand over a signed APK plus source and a short handoff note. If payment or tracking is included, I would confirm the backend and gateway first, since those are not quick add ons. Could you share the repo and the priority list so I can confirm what is realistic in 3 days before starting? Looking forward to hearing from you.

A live multi-vendor Kotlin/Java app, partial docs and a hard 3-day window: the risk is scope creep, so I'd lock the list on our kickoff call and ship exactly that. How I'd work: Day 1 build the repo, map the architecture (activities/fragments or Compose, ViewModels, API layer, Firebase or custom backend) and fix any launch blockers or crashes. Day 2 implement the agreed changes, e.g. checkout flow cleanup, a payment gateway (Razorpay/Cashfree) or live order tracking via FCM + maps. Day 3 regression pass on 2-3 Android versions, signed release APK, Git handover and a short maintenance note. Price: Rs 7,500 fixed for the 3-day round, paid on sign-off of the APK on your test device, as you described. Clean commented code, no rewrites of working parts. Questions: what backend does it use (Firebase, Laravel, Node)? Which 2-3 changes matter most for launch? Aakaash

Your live Android app needs a controlled final pass on the existing Kotlin/Java codebase, with the release blockers identified before changes begin. I’ve worked on production mobile applications and Java-based systems, so I’m comfortable tracing an unfamiliar codebase and working from partial documentation. I’d begin by building the repository, mapping its modules, and testing the current ordering flow on a real device. I’d then give you a written gap list and lock the exact three-day scope before implementation. Priority would go to crashes, broken flows, API failures, and agreed release-critical changes. I’d run regression checks after each change, generate the final APK, and hand over the updated source, configuration notes, and a concise changelog. Can you share the repository, current APK, documentation, and exact priority changes before awarding?
