Available for full-time & focused consultation work

Full-stack developer

Full-stack developer in Los Angeles focused on production-ready web applications.

I build software that helps businesses operate more efficiently. the kind of work that can go live without a week of last-minute patching. I’ve shipped sites and tools for nonprofits, e-commerce, and service businesses.

Currently interested in remote-friendly roles where I can own features end-to-end.

About

Full-stack with a product mindset.

Good software isn’t measured by the technologies it uses. It’s measured by how well it solves the problem it was built for.

I work directly with business owners to understand operational challenges before writing code. Whether I’m building an internal platform, automating workflows, or modernizing an existing application, my goal is the same: deliver software that users can rely on every day.

My work spans the entire development lifecycle from requirements gathering and system architecture to implementation, deployment, and long-term maintenance. I enjoy turning manual processes into software that scales with the business.

I’m comfortable owning a feature end-to-end: scoping, breaking work into shippable pieces, implementing, and tightening things up once real users touch it.

Process

How I like to work.

Simple, repeatable steps that keep projects moving without drama.

01 · Context
Understand the goal

Start with why the feature exists who it’s for, what “success” looks like, and what constraints we’re working with.

02 · Delivery
Ship a small version

Break work into thin slices that can go live quickly, with a clear path for follow-up improvements instead of a big-bang launch.

03 · Refinement
Tighten with real feedback

Look at actual usage, performance, and feedback, then refine UX and implementation where it matters most.

Next Steps

Let's Build Something Great.

I'm currently open to full-time software engineering opportunities and select freelance projects where I can build scalable products, solve meaningful problems, and contribute across the full stack.
