AI-focused electronic engineer and developer, training LLMs and building secure REST APIs and automation workflows for scalable systems.
ColombiaWhat I'm looking for
I’m an Electronic Engineer and AI Developer focused on building practical, secure AI solutions—from LLM training and evaluation to production-grade software. I enjoy translating messy requirements into reliable systems that teams can trust.
As a Freelance AI Developer & AI Trainer (Outlier AI), I designed 200+ structured prompts to detect logical flaws in emerging models, improving accuracy. I also evaluated, debugged, and optimized Python/Java/JavaScript code to reduce syntactic and logical errors in LLM outputs.
I validate end-to-end AI agent workflows that connect tools like n8n, Zapier, Make, Copilot, and OpenAI APIs, using advanced Prompt Engineering (Chain-of-Thought, Few-Shot, and System Prompts) to elevate response quality. I bring strong technical leadership and communication in Agile, cross-functional environments.
Alongside AI work, I’ve delivered real operations impact as a Service Deployment Analyst—administering remote Linux infrastructure, automating workflows with Power Automate/Power Platform, and implementing backup/preventive maintenance for continuity. Earlier, I digitized and migrated 500+ records to cloud using Microsoft 365 and SharePointOnline, cutting reporting time by 60% with Excel macros and SQL queries.
