What I'm looking for

I'm open to Software Engineer and Semi-senior Backend Developer roles, with a remote-friendly setup.

At CINC Systems, I develop Node.js and Express services for a multi-tenant property management platform. I designed an AWS S3 document management platform and a migration CLI that transfers production documents from legacy systems, with idempotent runs and automated transfer reports.

At MB Technology Solution LLC, I design and operate production LLM agents using Strands Agents SDK and AWS Bedrock, integrated into a NestJS healthcare application. I also work on evaluation suites, guardrails, and basic retrieval-augmented generation; earlier, I developed Python security monitoring tools and supported digital substation automation at HMV Ingenieros.
