Build Android E-Commerce App

@extreamcode

Hi, You’re not looking for a build-from-scratch team; you need someone who can step into an already-launched product and remove the hidden friction slowing growth. I’ve worked on PHP, Laravel, APIs, database optimization, performance fixes, and business apps where stability, speed, and clean iteration matter more than flashy rewrites. I can help review the backend architecture, improve API performance, tighten database structure, and support feature enhancements with clear documentation. On the app side, I’ll work closely with your team to improve UX flows, notification logic, chat reliability, and overall responsiveness while keeping the codebase maintainable for future scale. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. My focus would be on practical wins first: bottlenecks, crash points, and the parts of Map&Chat that affect retention and vendor activity the most. If you’d like, I can start by auditing the current stack and roadmap priorities this week so we can define the best next sprint. Which part of the current stack is the biggest constraint today: Android UX, backend APIs, or database scaling? Looking forward to your reply so we can finalize the exact plan. Best regards, Asad

Hi, I’m Mukesh. I specialize in improving and scaling already-live Android + backend systems, especially marketplace and real-time applications. Approach: I’ll start with a full architecture audit of the Customer, Vendor, and Backend systems to identify performance bottlenecks, API inefficiencies, and database issues. Then I’ll optimize UI/UX flows, refactor critical modules, and improve real-time features like chat, notifications, and search. Focus will be on stability, scalability, and clean maintainable code without breaking existing production flows. Deliverables: • Performance audit report (app + backend) • Optimized Android code (Kotlin/Java) • API & database performance improvements • Improved chat, search & notification systems • Scalable backend architecture fixes • Bug fixes + production stability improvements Clarifications: Q1. Current backend stack (Firebase / Node / Django)? Q2. Current daily active user load? Q3. Any critical pain points already identified? Let’s make the platform production-scale ready for growth.
