Hi, I can help enhance your existing **mobile and web applications** without disrupting current functionality. I have **9+ years of mobile development experience** with iOS, Flutter, APIs, Firebase, authentication, payments, notifications, and production deployments. I’m comfortable stepping into an existing codebase, understanding its architecture, and implementing targeted improvements rather than unnecessary rewrites. I can handle: • New features and UI/UX enhancements • REST API and third-party integrations • Authentication, notifications and payment flows • Backend/database updates • Bug fixing and performance optimization • Cross-platform testing and regression checks • Production builds, deployment and release support My approach is to first understand the existing architecture and requirements, identify dependencies and potential risks, then implement and test each change while keeping existing workflows stable. I focus on clean, maintainable code, clear communication, and practical solutions that can scale with the product. I’m available for ongoing development and can start by reviewing the current application, codebase, and first set of requirements.

Hi, I can help you to enhance your existing mobile and web applications without disrupting the current functionality. I’m comfortable working with existing codebases, understanding the architecture, adding new features, improving UI/UX, integrating APIs and third-party services, and fixing bugs. I can handle backend/database updates, authentication, notifications, payment integrations, performance optimization, testing, and production deployment support. I’ll focus on clean, scalable changes that keep the existing product stable while making it easier to extend in the future. A few quick questions: What technologies are currently used for the mobile app, web app, and backend? Can you share the existing codebase/staging environment for an initial review? Which add-on features or improvements should be prioritized first? Are any APIs, payment gateways, or notification services already integrated? I’m ready to review the current architecture and start with the highest-priority improvements. Regards, Abhishek

@poojatdsl

I can handle add-on development across your existing mobile and web applications, including new features, UI enhancements, API integrations, authentication, notifications, payments, performance improvements, bug fixes, testing, and deployment support. Approach: I’ll first review the existing codebase and architecture, identify dependencies and current workflows, then implement the requested enhancements without disrupting existing functionality. Changes will be structured cleanly and tested across mobile and web before production deployment. Suggestions: Establishing the current architecture, API flow, database structure, and deployment process first will make future add-ons faster and reduce the risk of regressions. Questions: What technology stack is currently used for the mobile and web applications? Can you provide the existing codebase/staging access and the first enhancement you want implemented? Ready to review the existing application and start with the first add-on.

You need new mobile and web capabilities added without destabilizing the existing product, which starts with understanding its architecture, dependencies, and current test coverage. I bring 9+ years across React Native, Flutter, Node.js, WordPress, APIs, databases, authentication, notifications, and payment integrations. At Poundit, I enhanced a production e-commerce platform built with Node.js and Django, including Stripe flows and customer-facing features where regressions directly affected live sales. I can audit the codebase, isolate each change, improve weak modules, add focused tests, and verify behavior across mobile and web before supporting deployment. I’m also comfortable translating Figma designs into responsive UI and investigating performance bottlenecks rather than masking symptoms. What frameworks and versions power the current apps, and which add-on features are highest priority?

I’ve gone through the scope carefully, and the main requirement here is being able to enter an existing codebase, understand its architecture quickly, and add functionality without destabilising what is already working. I can handle add-on development across mobile and web, including UI enhancements, API/third-party integrations, backend and database changes, authentication, notifications, payments, testing and deployment support. For each enhancement, I’d first trace the existing flow and dependencies, identify the safest integration point, then implement the change without unnecessarily restructuring stable modules. I’d also test the affected mobile/web flows and existing functionality after each significant update so regressions are caught before production. I can work iteratively as requirements evolve, with clean, maintainable changes rather than one-off patches. The first step would be reviewing the current codebase, environments and pending enhancement list so the implementation can be planned around the existing architecture. Share the repository, current tech stack and first set of add-on requirements, and I can assess the codebase and outline the most practical approach.

Hi, I understand you need an experienced developer to work on an existing mobile & web application — adding new features, integrating APIs, improving performance, and shipping production-ready updates without disrupting current functionality. I have solid experience working within existing codebases across both mobile and web: ✅ Feature additions & module enhancements on live apps ✅ API/third-party integrations (payments, auth, notifications, maps) ✅ Backend & database updates (Node.js, PostgreSQL, Firebase) ✅ UI/UX improvements following existing design language ✅ Performance optimization & bug fixing ✅ Cross-platform mobile (Flutter) + web (React) ✅ Testing & deployment support (Play Store/App Store/web) ✅ Clean, scalable, well-documented code My core stack is Flutter/Firebase with Node.js, PostgreSQL, React, and integrations like Razorpay, Stripe, Agora, RevenueCat — comfortable adapting to your existing architecture rather than rebuilding from scratch. I've handled ongoing enhancement work on production apps like Drivoo (ride-hailing) and Scan Cash App — happy to share references. Quick questions: What's the current tech stack (mobile & web)? What are the priority features/enhancements first? Do you have existing docs/API access ready? Ongoing or one-time engagement? Best regards, Vinod

@OnicoDigital

Hi, This looks like a good fit for our team. We work with specialists across full-stack web development, mobile applications and API integrations, including projects where the existing codebase needs to be extended rather than rebuilt. We’d first review the current application and stack, then work through the required add-ons, bug fixes and integrations while keeping the existing functionality stable. If you can share the current technology stack and the first feature or enhancement you’d like completed, we can assess the scope properly and confirm the most suitable developer. Kind regards, Maximillion Onico Digital

@netswaptech2811

Your requirement is not just feature development—it is extending an existing mobile + web product without disturbing stable functionality, while improving APIs, performance, integrations, testing, and production reliability. That is exactly where an experienced full-stack team adds value. Our approach would be: Existing codebase audit, architecture review and development/staging setup Feature-wise implementation with API/database changes where required UI improvements, authentication, notifications, payments and third-party integrations Performance optimisation, security checks and regression testing Production deployment with documented commits and handover I prefer milestone-based execution so you can review each enhancement before moving forward. We can also provide ongoing support rather than treating this as a one-off delivery. Two points I’d like to clarify: what is the current mobile/web technology stack, and do you already have a prioritised list of add-on features? I’d be happy to review the existing architecture and propose the safest roadmap before development begins.
