Work Experience

Full-Stack Developer

Marko AI

Dec 2025 - Present
  • Built geo-verified check-in workflow integrating Google Maps APIs with backend dwell validation (10+ min within 50m radius), ensuring visit authenticity before recording attendance.
  • Engineered proximity-based member discovery API using Haversine distance calculations with optimized PostgreSQL queries, delivering paginated responses (50 records/page) for scalable real-time matching.
  • Delivered real-time chat via Socket.IO with typing indicators and optimistic-send reconciliation, eliminating duplicate messages and reducing perceived latency.
  • Built secure JWT session management with access/refresh token rotation, token revocation, and session invalidation to prevent reuse of compromised tokens.

Associate Software Engineer

HCode Technologies

Jun 2025 - Nov 2025
  • Built Admin Dashboard with RBAC, user lifecycle management, and approval workflows, eliminating 12+ hours/week of manual operations; shipped with zero critical bugs verified via SonarQube.
  • Developed analytics report generation service with AWS S3 caching for repeat requests, reducing query latency by ~70% and eliminating redundant SQL execution on high-traffic endpoints.
  • Integrated SonarQube into GitHub Actions CI/CD pipeline, enforcing automated quality gates that resolved 95% of critical issues pre-release and reduced post-deployment defects.
  • Developed end-to-end user onboarding system with input validation, REST API integration, and structured error handling across frontend and backend layers, reducing onboarding-related support tickets.
