Full Stack Developer with 4+ years building scalable web apps using React, Angular, .NET, and Node.js. Cybersecurity-minded by default. Clean code, solid architecture, real results.

My background covers the full stack: responsive frontends with React and Angular; robust backend services with .NET, Node.js, and MongoDB; cloud deployments on Azure; and production integrations with tools like Docker, Redis, and AEM.
Beyond development, I have a genuine interest in cybersecurity how systems fail, how they get exploited, and how to build them so they don't. That mindset shapes how I approach every project: authentication flows, API security, input validation, and infrastructure hardening are part of the work from the start, not bolted on at the end.
I care about the quality behind the code clean architecture, meaningful test coverage, and solutions that are maintainable long after delivery. I've won two hackathons and consistently delivered across time zones for international clients.
What I bring to a project: clear communication, realistic timelines, and code you won't have to apologise for later.
Core stack: React, Angular, .NET, Node.js, TypeScript, MongoDB, PostgreSQL, Azure, Docker, AEM.

Project history
- Sole technical owner of an early-stage startup, effectively acting as CTO/tech lead worked directly with the client to define product direction and select the entire technology stack.
- Designed and implemented the full infrastructure and database layer from scratch, making all core architectural decisions independently.
- Built the backend in Node.js and the cross-platform mobile app in React Native, delivering the product end-to-end as a solo engineer.
- Owned the complete lifecycle from architecture and development through deployment and production operations.
Delivered full-stack applications and REST APIs for international clients; managed projects end-to-end in English
- Built the FindYourCoach platform from scratch: No-Code/Low-Code using WeWeb and Xano, PostgreSQL schema, and REST API integrations from concept to production.
- Containerized the entire stack with Docker; sole ownership of the architecture and production environment.
- Refactored and extended a vehicle-registration platform: new API endpoints and improved frontend flows.
