What I'm looking for

I’m looking for a product-focused team where I can own end-to-end delivery—building React/Next.js features, designing reliable APIs, and leveraging AWS infrastructure. I enjoy security-minded work and clear collaboration with stakeholders and design partners.

I’m a full-stack software engineer who ships production systems end-to-end, from SaaS features for Global 500 clients to sole-architecting a HIPAA-compliant healthcare platform on AWS. I specialize in React, Next.js, and TypeScript, with hands-on cloud infrastructure experience.

In my freelance work, I built a job-application tracking platform with a Chrome extension that pulls from LinkedIn and 10+ job boards, plus REST API routes using the OpenAI API to score postings and generate tailored cover letters. I also built an EMR platform deployed on AWS (Docker, ECS Fargate, RDS, VPC, ALB) with HIPAA-aligned security controls like bcrypt password hashing, audit logging, and role-based access.
