Hi, I’m Sebastian PE — a full-stack software engineer with 15+ years of experience building web products, backend systems, and developer tools.
What I Do
I work across the entire product lifecycle — from architecture and prototyping to launch and operation. My current focus:
- Go — high-performance backend services, concurrent systems, microservices
- AI & LLM Agents — prompt engineering, RAG pipelines, agentic orchestration
- PHP & JavaScript — full-stack web development, API design
- DevOps — CI/CD, observability, infrastructure as code
I’ve built e-commerce platforms, web portals, CRM and ERP systems, and business tools. I also have extensive experience as a team lead and head of development, managing engineering teams and designing software architecture.
