Senior Backend Engineer with 9+ years of experience building reliable, scalable systems in cloud environments. I design and ship production-ready backend services with Python, Django, and PostgreSQL — focused on correctness, concurrency control, and reliability under load.
I also bring a security-focused mindset from active vulnerability research on platforms like Immunefi and Sherlock, with confirmed high-severity findings in production systems.
- Production systems with Django, Django REST Framework, and FastAPI — layered architectures, JWT authentication, role-based access control
- Dual-interface backends serving both server-rendered views and REST APIs from a single codebase
- Security hardening: HSTS, secure cookies, CSRF protection, rate limiting, reverse-proxy headers
- Schema design, query optimisation, and migrations across PostgreSQL, MySQL, SQLite, and Redis
- Cloud infrastructure across AWS, GCP, and Azure core services
- Docker containerisation with multi-service stacks, health-check gating, and internal networking
- CI/CD pipelines with GitHub Actions — automated linting, testing, and deployment
- Infrastructure-as-code with Terraform for reproducible environments
- LLM integration (Claude, OpenAI, Mistral, Ollama) for summarisation, NL-to-SQL, and data processing
- MCP servers and clients enabling AI agents to interact with databases through standardised interfaces
- Automated pipelines — multi-source aggregation, LLM processing, and delivery to messaging platforms
- Active researcher on Immunefi, Sherlock, and Code4rena with confirmed findings in production systems
- Built penetration testing and forensic analysis tools in Rust and Python
- Vulnerability analysis, threat modeling, and secure architecture design
