About

Software engineer focused on backend systems.

I build systems that scale, integrate third-party services reliably, and design architectures with long-term maintainability and performance in mind.

Background

I started my career as a backend engineer at Sidetours, a B2B platform for booking tours and experiences. There I built and maintained REST APIs consumed by web and mobile clients, integrated multiple external providers — tour operators, payment gateways, availability systems — and worked on AWS infrastructure with Docker and CI/CD pipelines.

That experience gave me a solid foundation in what matters most: systems that work in production, scale without friction, and can be maintained by other engineers.

Today

I work independently as a software engineer and technical consultant. I help companies design and build backend systems, integrate third-party services reliably, and make architectural decisions that hold up over time.

My primary stack is PHP/Laravel and Java/Spring Boot for backend, with AWS, Docker and Terraform for infrastructure. I work with PostgreSQL, Redis, RabbitMQ and design APIs to production standards.

Engineering philosophy

  • The safest code is the code that does not exist. The simplest solution that works in production always wins.
  • Premature abstraction is technical debt with compound interest.
  • Well-designed systems are boring to operate. Boring is good.
  • Technical documentation is part of the system, not an afterthought.
  • Scalability starts at design time, not in reactive optimization.

Beyond code

I also teach programming and mathematics, and mentor engineers who want to grow in backend and systems design. My long-term interest is technical leadership: architecture, engineering decision-making, and building high-performing engineering teams.
