Web applications & online presence for small businesses

I design, build, deploy, and maintain the technology your business runs on — websites, booking systems, and the Google presence that brings customers in. One person, start to finish: you deal with me, and I do the work myself.

Web applications & websites

Off-the-shelf software never quite fits how your business works. I build the exact tool you need, then keep it running.

Online booking & scheduling systems — customers book on your website; you get notified by text and email; regulars are recognized automatically; no-shows can be blocked.
Custom web applications — customer portals, quote and estimate tools, dashboards, and internal tools that replace spreadsheets, paper forms, and double entry.
Business websites — fast, mobile-first websites built to turn visitors into calls, bookings, and directions to your door.
The full cycle, one developer — design, code, deployment, and maintenance. No agency hand-offs, no account managers, no waiting on a ticket queue.

See it live: I built the website, Google presence, and a custom online booking system for my family's salon, A+ Nails of Rowlett.

Online presence & marketing

Most small businesses are nearly invisible online — and don't know it. Customers pick whoever Google shows first, with the best reviews. I fix that.

Google Business Profile — set up and optimized so you show up in Google Maps and "near me" searches, with the right hours, services, and photos.
Reviews that sell — simple systems to earn more Google and Yelp reviews, and a professional response to every review, good or bad.
Listings everywhere customers look — Google, Yelp, Bing, and Apple Maps: accurate, consistent, and complete.
Local search — your services plus your city, ranking where it actually pays.
Social presence — Facebook and Instagram pages set up properly and kept active.

Care plans & automation

A website is not a one-time purchase — it needs looking after. My care plans cover it for a flat monthly fee:

Hosting, updates, backups, and security — handled. You never think about the technology.
Small changes included — new hours, new services, new photos: text me and it's done.
Reminders & follow-ups — automatic appointment reminders by text and email cut no-shows; follow-up messages bring past customers back.
Professional business email — yourname@yourbusiness.com instead of a free email address, set up and working on your phone.

Why businesses hire me

25+ years building software — Senior Software Engineer at IHS Markit Energy (Fortune 500) for a decade; software roles at Santander Consumer USA and Dover Corporation; Product Manager since 2018.
Formally trained — B.S. in Computer Science and M.S. in Information Technology & Management, both from The University of Texas at Dallas.
A business owner myself — I run the technology for my family's salon, so I build what a real small business actually needs, at a price that has to make sense.
Project work only — I take projects and deliver them myself, by the job. I am not looking for a staff position, and I do not outsource your project.

Pine Script, for traders: I write custom TradingView indicators by the project — a private suite of 13 systems of my own, including a regression-channel engine refined through 941 versions, a 38-symbol scanner, and a machine-learning trend estimator; seven of my scripts are published on TradingView.
