Senior Backend Engineer building reliable distributed systems with a pragmatic mindset. Turning engineering knowledge into reusable tools, playbooks and automation.

I enjoy solving difficult engineering problems and turning what I learn into reusable knowledge.

What motivates me:

• Designing backend systems that are simple to operate, resilient under failure and pleasant to maintain.
• Building systems that don't just work on day one, but continue to be understandable and maintainable years later.
• Taking on challenging problems that push me outside my comfort zone.

I believe good engineering is less about mastering every framework and more about developing judgement to make the right trade-offs.

Some principles I try to follow:

• Build simple systems before scalable ones.
• Reliability is a product capability.
• Optimize for maintainability.
• Design with observability from day one.
• Automate repetitive work.
• Document important decisions.
• Pragmatism over hype.

A self-hosted AI-powered knowledge management platform.

A production-oriented pipeline that ingests technical content, enriches it with LLMs, generates embeddings and publishes a searchable knowledge base.

Focus areas:

• AI-assisted workflows.
• Retrieval-Augmented Generation (RAG).
• Long-term knowledge management.
• Production-grade architecture.

Exploring support for the emerging HTTP 'QUERY' method in Spring Boot.

The project evaluates current framework support, experiments with modern HTTP semantics beyond traditional REST and aims to become a reference implementation for developers exploring this emerging HTTP method.

A collection of practical playbooks, checklists and decision guides extracted from real-world backend engineering experience.

Currently exploring context engineering, AI-assisted software development and development workflows that improve engineering productivity without replacing engineering judgement.
