Luis MendezSoftware Engineer — Backend, SOA & Integrations
6+ years building and modernizing mission-critical enterprise systems in Python, .NET, and React on AWS. Part of the backend team behind an AI-powered policy issuance platform that cut processing time from 8 days to 3 minutes — published as an official AWS case study.
About Me
I build and modernize the backend systems that large organizations run on. I'm a Software Engineer with 6+ years of experience across insurance, the public sector, and product companies, based in Santo Domingo, Dominican Republic.
Today I work as an SOA Analyst at Grupo Humano — the largest insurance group in the Dominican Republic — designing the service-oriented integrations that connect core business platforms. I was part of the backend team behind PAO, an AI-powered policy issuance platform (Amazon Bedrock, Amazon Nova Pro, AWS Step Functions/Lambda/S3) that cut issuance time from 8 business days to 3 minutes, with over half of all applications processed with no human intervention — published by AWS as an official case study.
Alongside full-time work, I've delivered 10+ freelance projects for small and mid-sized businesses since 2019, with systems running in production since 2020 — owning requirements, architecture, development, deployment, and support end to end.
