I'm a passionate Software Engineer with 10+ years of hands-on experience across backend engineering, fintech systems, geospatial platforms, AI/ML, and DevOps. I enjoy building scalable, secure, and resilient systems with clean code and real-world impact.
- ⚙️ Build high-performance backend systems and microservices (Spring Boot, Django, Go and Rust)
- 🏦 Engineer fintech and banking platforms: escrow, reconciliation, billing, ledger systems, and Redis-based idempotency
- 📈 Build high-frequency trading (HFT) systems in Go and Rust, focused on low-latency algorithmic trading and fast order execution
- 🗺️ Architect multi-tenant geospatial SaaS platforms with PostgreSQL/PostGIS, GeoJSON, and Shapefile processing
- 🤖 Develop AI-powered systems using RAG, LangChain, LlamaIndex, vector databases, and local LLMs (Ollama)
- 📡 Design secure, efficient REST, gRPC, WebSocket, and WebRTC APIs with JWT, OAuth2, and RBAC
- 🔄 Build event-driven architectures with Kafka, RabbitMQ, and AWS SQS for scalable asynchronous workflows
- 🛡️ Implement resilience patterns: circuit breakers, rate limiting, retries, and fault isolation
- ⚡ Optimize performance with Redis and Hazelcast caching, query tuning, and custom indexing
- 🚀 Ship with CI/CD pipelines using GitHub Actions, Docker, and Nginx, monitored with Grafana and Prometheus
