Sebastian Betancur Salazar
Senior Software Engineer
Hi, I'm Sebastian — I've been designing and building web platforms for 9+ years.
These days, I build them with AI agents by my side.
Tailor my pitch
If you're hiring for Salesforce B2C Commerce — I've spent 4+ years deep in SFRA, SCAPI and OCAPI, leading headless integrations and OMS syncs that actually ship.
How I work
AI-Driven Engineering
Specs before code, agents doing the work, and a harness that keeps them honest — applied to real commerce integrations, not demos.
Spec-Driven Development
Requirements, design and tasks written before code — for commerce APIs and integrations alike.
Harness Engineering
CLAUDE.md/AGENTS.md, hooks and guardrails that let agents work reliably in a real codebase.
Agents & Skills
Custom skills and subagents for recurring work — SFCC cartridges, jobs, hooks, SCAPI.
AI-Assisted Delivery
Copilot and agentic review woven into day-to-day code review, testing and documentation.
