I am a senior software engineer with 10+ years of experience delivering robust, high-performance solutions across Microsoft, Cadence, and Oracle. My core expertise spans C++ development, backend architecture, and scalable data systems.
In my freelance work, I’ve recently built production-grade backends for fintech/crypto clients, including a Crypto Data API (FastAPI · Redis · PostgreSQL) that unified multiple providers (CoinGecko, CryptoQuant) into normalized endpoints. The system featured background workers, Redis caching for sub-200ms responses, Postgres persistence for analytics, and secure access controls with rate limiting and admin tooling.
I specialize in:
---Modernizing legacy codebases (C++/backend refactoring).
---Designing high-throughput APIs with FastAPI/NestJS.
---Integrating distributed workflows with Kafka & real-time data.
---Building resilient storage layers in Postgres, MongoDB, and Redis.
I work with precision, accountability, and a strong focus on reliability and scalability. Whether extending thick client applications, designing APIs, or integrating complex data pipelines, I ensure production-grade quality with minimal supervision.
Typical Workflow:
Requirement clarification → Architecture & planning → Incremental development → Regular demos/updates → Production-ready delivery.
Skills Snapshot:
Languages: C++ (11/14/17/20), Python, TypeScript
Frameworks: FastAPI, NestJS, Qt, React
Data: PostgreSQL, MongoDB, Redis, Kafka
Cloud & Tools: Docker, GitHub Actions, DigitalOcean
What You Get
- Clean, well-structured code with documentation
- Production-ready APIs and data pipelines
- Transparent communication and regular updates
- Focus on reliability, scalability, and maintainability
- Iterative, collaborative approach that adapts as requirements evolve
