Independent consultant · 100% remote
Backend systems and architecture,
built to ship.
I'm Valentin, software engineer & architect with 10 years turning complex problems into reliable systems: scalable backends, APIs, distributed systems and applied AI/LLM. From scoping to production.
Services
How I can help
Three areas where I bring senior, hands-on expertise, from architecture to shipped, production-grade software.
Software architecture
System design that scales, from a blank page or as senior reinforcement.
- Architecture & technical roadmaps
- Scalability & reliability
- Technical due diligence
Backend development
Robust, high-performance services and the infrastructure around them.
- APIs & data pipelines
- Distributed & event-driven systems
- Infrastructure & observability
AI / LLM engineering
Applied AI taken from prototype to production, not demos.
- LLM agents & tool-use
- RAG & retrieval pipelines
- Workflow & process automation
Why work with me
Senior, hands-on, from design to production
10 years, in the trenches
CTO and software architect. I design the system and build it myself, across stacks and demanding contexts.
From zero or in reinforcement
Greenfield systems built from scratch, or embedded with your team to unblock and accelerate delivery.
Production-grade by default
Robust, secure and scalable, built on a decade of mission-critical, high-stakes systems.
Selected work
Projects & case studies
A few representative engagements. Each links to a detailed write-up, context, problem, approach and results.
