Prompt rules alone had GPT-4o inventing IDs to satisfy them. Moving them into a strict response schema got 8 of 10 structural checks passing. The feature is still in build.
Sole engineer since early 2025 on a pre-revenue M&A integration SaaS, after 6 months paired with a senior engineer.
Looking for a founding or early engineer role at a funded pre-seed to Series A startup with real LLM work. No sponsorship needed, full US-hours overlap. Contractor is fine. Open to a paid 4-week build as a trial.
Remote: Yes (also open to hybrid in Costa Rica's Central Valley)
Willing to relocate: US citizen based in Costa Rica
Technologies: Java/Spring Boot, Angular/TypeScript, Azure (SQL, Entra ID, OpenAI), LLM features (structured outputs, validation), Claude Code + MCP agent pipelines; some React/Next.js
