I'm a Backend Software Engineer specialized in building transactional, production-grade systems that support real business operations.
I focus on data integrity, state management, and scalability. I believe good software is measured by how well it handles edge cases — not just happy paths.
My strongest expertise is in Backend development with Laravel / PHP, complemented by TypeScript and React when required to support full system workflows.
I have experience delivering production-focused backend systems for private client platforms with strong transactional requirements.
Most projects are private due to client confidentiality.

I work on backend systems where correctness, consistency, and reliability are critical.
I’m especially comfortable in environments that involve:
- Complex transactional business flows
- State-heavy systems (payments, reservations, stock, accounting)
- High impact architecture decisions
- Long-term maintainability and scalability concerns
I value clear ownership, thoughtful system design, and engineering decisions that reduce operational risk in production systems.
Long-term, I plan to build a software consultancy delivering scalable, maintainable, and business-oriented systems.
