High-impact Backend Engineer specialized in building production-grade systems from the ground up. Deep expertise in Java, Distributed Systems, and Database Internals. I don't just use tools; I build them—from custom database engines with MVCC to dependency-aware build systems.

🎓 Stratis - AI-Native EdTech Platform
(Frontend Repository available here) Architected a resilient microservices platform handling real-time AI interactions with millisecond latency.
- Database Optimization: Achieved 80% latency reduction (450ms → 90ms) by eliminating N+1 queries using Hibernate Entity Graphs and JDBC Batch Processing across 12+ relational tables.
- Resilient Architecture: Implemented Resilience4j Circuit Breakers and a dual-layer caching strategy (PostgreSQL → Redis), reducing API costs by 75% while maintaining <200ms P95 latency.
- Real-Time Eventing: Built a decoupled analytics pipeline using Kafka to ingest 15+ user interaction types with <100ms latency, enabling real-time ML diagnostics.
- Observability: Deployed full distributed tracing with Sentry and Prometheus metrics to monitor circuit breaker states and system health.
🏛️ TitanDB - Production-Grade Database Engine
Built a complete database engine from scratch, implementing the same low-level concepts that power PostgreSQL and MySQL.
- Storage Engine: Implemented a self-balancing B+ Tree for O(log n) indexing.
- Concurrency: Designed a Multi-Version Concurrency Control (MVCC) system for lock-free reads.
- Durability: Integrated Write-Ahead Logging (WAL) and the ARIES recovery algorithm to ensure ACID compliance and <100ms crash recovery.
- Performance: Benchmarked at 50-80K ops/sec for concurrent reads with a 99%+ buffer pool cache hit rate.
⚙️ MyCoq-Build - Dependency-Aware Build & Runtime System
Architected a custom build and execution engine for complex Java environments.
- Build Logic: Developed a topological sort-based engine for dependency-aware building.
- Runtime Isolation: Engineered a service execution engine using Custom ClassLoaders to provide true runtime isolation between services.
- Lifecycle Management: Built a complete CLI to manage service registries, dynamic loading, and graceful shutdowns.
