I build scalable SaaS platforms and enterprise web applications from architecture to production.

I've led the architecture and full-stack development of Intuitta's multi-tenant ATS SaaS platform, supporting 1,500+ active recruiters and HR teams. I defined its API contracts, database schema, development standards, and AWS production infrastructure.

I improved deployment time by 40%, reduced release-related incidents by 30%, achieved 99.9% uptime, and cut average API response time by 35% through PostgreSQL optimization. I've also mentored 4+ engineers and worked closely with product leadership to turn roadmaps into scalable technical solutions.

Previously, I built healthcare applications at Newfire Global Partners and delivered eCommerce, CRM, analytics, FinTech, and booking platforms at One2Team and Binom using React, Node.js, Rust, Go, PHP, and cloud-native tooling.
