Need a working web app — not another WordPress brochure?

Most web designers install a template on WordPress or Wix. You get a static site that looks fine and does almost nothing. It will not log people in, store your data, take bookings, or stay patched after launch.

I am a web app creator. I design and build the application, put it behind Cloudflare so the public internet cannot hit your server directly, and stay on as the person who keeps it running and upgrading. One person. No agency handoff.

What you actually get

1. I build it

Custom web applications shaped around how your business works — from first sketch through launch. Logins, dashboards, calendars, client portals, payments, and AI features where they genuinely save time. Built on Django and Vue, not a rented page builder. Works on phones, tablets, and desktops.

2. I keep it running

Software is not finished at launch. I host it, watch it, back it up, and upgrade it so you can run your business instead of babysitting a website.

• Automatic database backups and tested recovery
• Security patches and dependency updates
• Ongoing upgrades as your needs change
• Flat monthly maintenance — no surprise invoices

3. I keep it safe

Your app sits behind Cloudflare. Malicious traffic is filtered at the edge, bots and scrapers are blocked, and the origin server is locked down so only Cloudflare can reach it. I am CCNA certified — I set up the network and firewall, not just the pages.

What I can build for you

• Client / staff portals: Secure logins (including email two-step verification), roles, and a place your people actually work.
• Appointment and booking calendars: Consultations, B&B / hotel rooms, or any slot-based schedule — with email confirmations.
• Shift scheduling and clock-in/out: Replace the whiteboard and the three different apps your staff currently juggle.
• Inventory, e-commerce, and payments: Product catalogs, Stripe checkout, subscriptions.
• AI that is already running on my own site: private chat on a local language model (your data stays on the server), voice-to-text for meetings, and document Q&A with citations.
• A single data hub: Pull sales, attendance, and supplier numbers into one dashboard instead of hopping between Square, Homebase, and MarketMan.

Tech I actually ship with

I write the code. I also run the production box.

• App: Python Django + Vue.js, PostgreSQL, real-time WebSockets
• Ops: Docker, automated backups, health monitoring
• Security & delivery: Cloudflare (WAF, bot protection, origin lockdown) + R2 file storage / CDN
• AI: Local LLMs (Ollama), document Q&A, voice-to-text

Why work with me?

I run Dodam LLC out of Oakland and have been building and maintaining web apps for small businesses and neighbors since 2023. I am a full-stack developer and CCNA — not a designer who outsources the hard parts. Face-to-face is fine. When something breaks, you call the person who built it.

Before software I spent fifteen years as a research scientist (PhD, then genomics work at UC Berkeley). I ask a lot of questions before writing code, and I care whether the data underneath your app is correct.
