Senior full-stack developer delivering scalable marketplaces, SaaS, and mobile platforms.
What I'm looking for
I am a senior full-stack developer with eight years building marketplaces, SaaS platforms, and mobile applications that drive measurable business results.
I have led end-to-end system design and project delivery, including a multi-vendor marketplace using Node.js (NestJS), TypeScript, React, and PostgreSQL that supports 100+ vendors and thousands of products.
My work emphasizes modular architectures, API integrations, and UX-driven frontends—I created a backend plugin system reducing development time by 35%, integrated Stripe Connect to handle $500K+ monthly, and implemented Algolia search for 10,000+ products.
I collaborate closely with designers and cross-functional teams, optimize performance and uptime, and prioritize reliable, maintainable systems that improve workflows and onboarding while ensuring security and scalability.
