Experienced Backend Software Engineer with 3.8+ years building high-throughput microservices for FinTech and WealthTech platforms. I specialize in designing scalable Spring Boot microservices, RESTful APIs, and event-driven systems using Apache Kafka for real-time data streaming.
What I bring:
- End-to-end backend development in Java, Spring Boot, Spring Security & Spring Cloud
- Database design and optimization with PostgreSQL, Redis, ClickHouse, and TimescaleDB
- Real-time data pipelines using Apache Kafka and PySpark, handling high-volume streaming data
- Secure API development with OAuth 2.0, OpenID Connect, RSA/AES-256 encryption, and PCI-DSS compliant systems
- Containerized deployments with Docker, Kubernetes, and GitOps (ArgoCD), with full CI/CD via GitLab
- Performance tuning using GraalVM Native Image, resilience patterns (Circuit Breaker, Retry), and full observability stacks (Prometheus, Loki, Grafana)
Proven track record:
Built and shipped 15+ production microservices supporting 100K+ active users at a stock broking platform (ORCA). Delivered an 85% query latency improvement by migrating analytics storage to ClickHouse, and reduced JVM startup time by 80% using GraalVM. Engineered secure payment gateways and partner SSO integrations for financial trading systems.
What sets me apart:
I don't just write code — I build reliable, production-grade systems with a strong focus on security, performance, and observability. I communicate clearly, deliver on time, and treat every project like it's my own product.
Whether you need a new microservice architected from scratch, an existing system optimized for performance, or a secure API integration built — I'm ready to help.
