About Bastian
Looking to take your product from idea to a running, production-grade platform without juggling three different specialists?
I'm Bastián, a Full-Stack Engineer who builds complete web applications end to end and ships them secure by default. Backend, frontend, infrastructure, and the security layer most teams add too late: I cover all of it.
What I build for you:
- Full platform, A to Z. Backend in Go and Python (FastAPI), frontend in React and TypeScript, database design, and deployment. One person owning the whole stack means fewer handoffs and faster delivery.
- Secure by design. I come from offensive security (banking, energy, and critical-infrastructure pentesting). I build identity and access management (Keycloak, OAuth2/OIDC), secrets management (Vault/OpenBao), and hardened infrastructure into your product from day one, not as an afterthought.
- Production-ready infrastructure. Kubernetes, Docker, CI/CD pipelines, and GitOps. I deploy on cloud or on-premise and set up the monitoring so you actually know what your system is doing.
- AI integration. LLM-powered features and workflow automation wired into your backend, with the security review AI features usually skip.
What you get:
✅ A clear technical plan before any code is written
✅ A working MVP, fast
✅ Identity, authentication, and secrets handled properly
✅ A backend and API that scale
✅ Infrastructure and deployment you can maintain
✅ A security posture that holds up under real scrutiny
I've shipped applications reaching 10,000+ users, run production platforms for my own clients, and tested systems across banking, energy, and critical infrastructure.
Have a complex build, a security concern, or an MVP that needs to reach production? Let's talk for 20 minutes and map out how I can help.
