Hire the Best Sharetribe Specialists

I’m Bablu Kumar, a senior full-stack web developer with 7+ years of experience building scalable platforms, complex systems, and marketplace products that handle real users and real payments. I work with founders who need more than basic development — they need systems that are reliable, extensible, and built for real-world use. My core expertise includes React, Node.js, Ruby on Rails, Laravel, Stripe with advanced payment flows and webhooks, AWS S3, and AI integrations using ChatGPT and OpenAI APIs. I focus on clean architecture, strong coding standards, and maintainable systems so products can grow without constant rewrites or technical debt. I build MVPs that launch fast but are engineered for long-term scale. I’m also a verified Sharetribe expert, bringing deep marketplace experience when required — from payments and workflows to edge cases and platform limitations.
