Open to interesting collaborations

From Traditional Systems to Modern WebApps

With full-stack development experience since 2015, I've architected systems that bridge operational needs with technical innovation. My journey spans from legacy PHP systems to modern React/React-Native/Next.js applications, always focused on solving real business challenges.

Pioneered: Built mission-critical systems including ERP-to-SAP integration, custom Mapbox routing servers, and SOP enforcement platforms with media verification.

Leadership Milestone: Transitioned from developer to early sr. software developer in 2018, subsequently owning the entire SDLC for most projects - from requirement gathering to deployment.

Key Systems Delivered:
  • SOP enforcement platform with media verification
  • Real-time marketplace infrastructure with WebSocket/Node.js core
  • Custom Mapbox routing server for ride-hailing services

Current Focus: Modernizing web application stacks with Next.js with backend powered by microservices architecture.
