About

I'm a Java Backend Developer focused on building systems that work in production — not just on localhost. I care about clean architecture, transactional integrity, and APIs that scale.

My core stack is Java & Spring Boot on the backend and React.js on the frontend. I write layered, maintainable code — service layer, persistence layer, no shortcuts.

Actively looking for Java Backend Developer or Full Stack roles where I can contribute from day one.

Projects

01
SkyTrack — Flight Delay System
● Live

Event-driven Spring Boot API that auto-generates passenger alerts and sends real emails when a flight is delayed or cancelled. Full-stack with React frontend.

  • State machine enforces valid flight status transitions — invalid transitions rejected at service layer
  • @Transactional ensures status change + alert creation rollback together on failure
  • Email wrapped in try-catch — alert DB persistence guaranteed even if SMTP fails
  • Deployed on Render with PostgreSQL (Neon) via Docker

Airport Management System

Console-based Java application with full CRUD for passengers, flights, and bookings using raw JDBC and strict DAO architecture.

  • Duplicate seat validation enforced at DB level via unique constraints — not just application layer
  • Booking cancellation auto-restores seat count — no inconsistent state possible
  • Zero logic leaking into persistence layer — clean DAO separation throughout
