Solo-built and currently operate Framework for Interoceptive Exploration, Language and Design - FIELD (aifield.tech), a 5+ mode AI orchestration platform live in Preview since March 2026. Strict TypeScript throughout, multi-provider LLM routing across Anthropic and OpenAI, three-layer content safety pipeline, client-side AES-256-GCM encryption, PostgreSQL with row-level security.
Before that, ten months building production voice agents at a Canadian AI startup. Multi-prompt architectures with conditional handoff running across thousands of live calls, CRM and booking integrations, custom analytics endpoints for failure triage. Intern to full-time on delivered work.
~18 months professional. Finishing a CS degree (University of Manitoba, December 2026), so ~20 hrs/week until then and full-time from January. Happy with contract or hourly. Native Portuguese, fluent English.
Most interested in: LLM systems where the hard part is judgment rather than plumbing, like agent behaviour, evaluation, safety surfaces.
