Implemented core services for accounts, ledger, transfers, and authentication, supported by an API Gateway with centralized routing, service discovery with Eureka, and containerized deployment via Docker Compose.

Core Banking System

A production-oriented database migration tool designed to execute schema changes in a safe, deterministic, and transparent way using plain JDBC and a CLI-driven architecture. The tool focuses on transactional correctness, controlled failure handling, and predictable behavior in CI/CD pipelines, rather than relying on framework-level abstractions. Key features: - Framework-independent, pure JDBC implementation - Transactional migration execution with explicit commit / rollback boundaries - Configurable Failure Strategy (STOP / CONTINUE) controlled via CLI - Checksum validation to detect modified migrations and prevent silent schema drift - Database-level locking mechanism to avoid concurrent migration execution - CLI-first design for easy automation and pipeline integration - Minimal and strict model: only successfully applied migrations are recorded This project was built to deeply understand how migration engines (like DB Maestro) work internally (transaction scope, failure semantics, checksum safety, and locking), rather than treating database migration as a black box.

Devsync is an AI-powered pull request and commit analysis platform designed to streamline code review processes. It integrates with GitHub through OAuth and webhooks, automatically analyzing pull requests, evaluating commit quality, and assigning risk scores. The platform leverages AI models to generate technical, architectural, and functional feedback, helping teams identify potential risks earlier in the development cycle. Future releases will include a team activity dashboard and deeper repository insights.
