I'm Andres Perez, a full-stack .NET & AI-augmented engineer building production systems and shipping my own SaaS products. Currently modernizing enterprise platforms at Columbia Southern University with Next.js, React, and Claude.
From AI-native SaaS to native iOS apps in production, products built end-to-end, with real users and real outcomes.
AI-native SaaS
An AI-native notifications platform. The Basic tier is live today, with Pro and Elite tiers on the way, bringing more power to how teams turn signals into the right message at the right time.
Product · Platform
A platform for going from idea to shipped SaaS faster, the systems, scaffolding, and AI workflows behind launching software products. Currently in the founders stage, being built in the open.
Native iOS · Healthcare
A native iOS app helping hospital patients video-call loved ones through camera-equipped Smart TVs. Featured by CBS News for connecting families in the Mother-Baby Unit at St. Anthony's Hospital.

I'm a software engineer based in Fort Pierce, Florida, specializing in .NET with real-world experience delivering apps that connect, inform, and empower, from mobile tools for hospitals to enterprise portals for online universities.
My career began in healthcare, where I logged over 3,500 clinical hours and built more than a decade of industry experience. That foundation shapes how I build software: with empathy, precision, and a focus on positive user impact. I'm also a committed mentor, I've led group trainings of up to 30 people, contributed to developer standards, and currently coach an intern.
I've shipped hospital apps on a .NET + Azure backend featured on CBS News, maintained U.S. Navy readiness tools, and now build mission-critical platforms at Columbia Southern University, transitioning front-end applications from ASP.NET to React, Next.js, and TypeScript.
Five-plus years of production .NET and SQL Server, paired with a modern front-end stack in TypeScript, React, and Next.js, with AI-augmented engineering at the center of how I work.
Daily Claude Code & GitHub Copilot user. I treat the LLM as a paired-programming partner, every output reviewed, tested, and human-verified before merge.
5+ years of production C# across healthcare, government, insurance, and enterprise education, the language I reach for first.
Author complex stored procedures, tune queries, and ship safe schema changes, on SQL Server and Azure SQL since day one.
REST APIs, MVC apps, and Razor pages, the backbone of every enterprise system I've shipped, from Azure-backed mobile APIs to high-traffic portals.
Strict-typed TypeScript across both the front-end and serverless code I ship, non-negotiable at the scale of systems I work on.
Modern React 19 / Next.js, including the front-end modernization of a high-traffic Prospect Portal from ASP.NET Core to a Next.js stack.
App Service, Azure SQL, and Notification Hubs, the cloud backbone behind the .NET and healthcare apps I've shipped to production.
AWS CDK, Lambda, DynamoDB, Cognito, and API Gateway, comfortable building serverless TypeScript backends end-to-end.
Semantic HTML, accessible CSS, and clean JavaScript, the foundation under every front-end I build.
Leading the ground-up replacement of a legacy ASP.NET MVC/WebForms student portal with a modern Next.js 16 / React 19 / ASP.NET Core stack across four role-based experiences (Student, Prospect, Professor, Admin). Operating with Claude as a paired-programming partner, I've personally delivered 66% of all frontend commits while maintaining strict 1:1 production parity.
