About

I’m Victor Sesma. I build backend systems and I care about clean architecture, reliability, and pragmatic engineering.

This site is where I document what I learn while designing and shipping systems—especially where AI changes the shape of backend work. I’m not interested in hype or “AI demos”. I’m interested in constraints, failure modes, and trade-offs.

What I work on

• Backend architecture and distributed systems (often in Go)
• Reliability: observability, incident-minded design, production ergonomics
• Applied AI systems: constrained assistants, RAG, human-in-the-loop workflows

How I think

I like approaches that are:

• Explainable: you can reason about behavior and failure cases
• Testable: there’s a path to confidence in production
• Operational: metrics, logs, and clear ownership are first-class
• Pragmatic: the simplest solution that meets the constraints

What you’ll find here

• Short technical notes
• Case studies from real projects (with limitations and mistakes included)
• Architecture write-ups focused on decision-making, not buzzwords
