Projects & Recommendations

Selected Work

13 years of production work, most of it behind client NDAs. What I can show sits below: the platforms I built and ran for 8+ years, the AI work I’m on now, and three public recommendations. The early Elance projects and my training material I can walk you through in full. Just ask.

What I’ve built

8+ years

Cloud Platforms + Mobile Apps (iOS & Android)

This is the work I do full-time: I’m a senior software engineer at Nu-login, where I started on the back-end cloud side, standing systems up from scratch on DigitalOcean for their clients, then grew with the products. That meant REST APIs feeding native iOS and Android apps, custom Android modules where the cross-platform layer ran out, and the ops work that keeps a system alive years after launch.

Current focus

AI Integration & Agents

The layer I work in now: wiring LLMs into a back-end that already exists, usually a Laravel API or a Node.js service. RAG pipelines for document Q&A, MCP servers so an agent can call internal tools without being handed every key, and a human approval step on anything that carries real risk. So far that has meant internal tooling and client projects under NDA.

The platforms above are the kind of build my studio takes on end-to-end.

LinkedIn recommendation

Elvis is an extremely well-versed coder with a wide array of skills, who’s always readily available to help with urgent projects and issues. His communication is excellent. You can be sure he goes out of his way to overdeliver on project requirements and make recommendations you may not have even thought of. If you get the chance, hire this guy.

Elvis helped me with two website design projects. At first I was concerned about the time and language differences, but I immediately discovered that I had nothing to worry about. Elvis was always easy to contact and easy to work with. He was able to complete the projects on time and the results were excellent. I strongly recommend Elvis, and will hire again for future projects.

I’ve been working remotely with Elvis for almost a year now. He supports my company with various coding issues with regards to our web design operation. At first I was concerned that the distance between us would be a problem, but I soon discovered it was a non-issue. Elvis doesn’t sleep, or if he does it’s very little, because despite the fact that I am on the west coast of the United States, he always seems to be available to communicate.

Elvis is quick and responsive, with an ability to understand our needs quickly. He stays with a job until we and our clients are fully happy, which is wonderful. I would highly recommend him for any web coding projects.

What this turns into depends on you: project work, a workshop for your team, or a 1:1 coaching hour.

Curious about the parts I couldn’t show? Ask. I’ll show what I can and say plainly what stays private.
