What I bring to a project

01

AI products & agents

I've shipped autonomous agents, streaming LLM features, and AI-assisted workflows into production platforms. Multi-model strategies keep costs under control while the intelligence goes where users feel it.

Full-stack engineering

Laravel and PHP at depth, plus React, Next.js, Angular, Vue, Node, Go, and Python. Enterprise CMS work on Drupal 10. I match the stack to the problem and keep the architecture boring where boring wins.

DevOps & delivery

CI/CD pipelines I design and own, containerized deploys, microservices, and cloud infrastructure on AWS. On ARProactive I ran delivery for a 12-developer team, so process is part of my toolkit, not an afterthought.

About

Why clients keep me around

Eight years in, my pattern is consistent: clients bring me in for one job and keep me for years. My longest engagement ran four and a half years and 9,397 hours on a single contract. My most recent yearlong contract closed at nearly 2,000 hours with a 5.0. That doesn't happen because of any one framework. It happens because the work ships on time, the code stays maintainable, and communication never goes quiet.

I work across the whole product: backend services, frontend features, AI integration, and the CI/CD pipelines that deliver them. On ARProactive I introduced AI-assisted code review across a 12-developer team. On enterprise platforms like Acquia's, I worked to the security, performance, and compliance standards that large organizations demand.

I've earned $300K+ and logged 17,000+ hours on Upwork with a 100% job success score and Top Rated Plus status, which Upwork reserves for the top performers on large contracts.
