Austin-based fractional CTO, senior developer, AI builder, and tech creator
Ship useful software before the window closes.
I am David Levine Bramante, founder of CodexDeus. I help founders and businesses turn practical ideas into websites, web apps, mobile apps, desktop apps, Chrome extensions, AI agents, and product launches people actually use.

Execution Is the Product
The market changed. AI-assisted development compressed timelines. What still matters is taste, judgment, speed, positioning, and whether real people keep using what you ship.
Ideas are a dime a dozen. Software execution is easier and faster than ever.
The hard part is choosing the right slice, shipping it, and getting people to use it.
A product with users beats a perfect architecture no one touches.
I build fast because speed is now part of the product strategy.
What I Build
Services are structured around the kind of product you need, not bloated agency retainers. The goal is to get from idea to a usable release quickly, then improve from real usage.
Websites
Fast, credible sites that explain the offer and create leads.
Web Apps
Dashboards, portals, SaaS products, workflows, auth, payments, and AI.
Mobile Apps
React Native and iOS builds for MVPs, internal tools, and launches.
Desktop Apps
Mac, Windows, Electron, Tauri, Swift, and local-first software.
Chrome Extensions
Browser tools that live where your users already work.
AI Agents
Claude, OpenAI, voice agents, automation, and internal copilots.
Fractional CTO
Architecture, hiring, vendor audits, product strategy, and rescue work.
Current Work
I am launching and updating sites and apps nearly weekly. These are the kinds of practical builds I want more of: specific markets, clear users, fast iteration.
Green Screen Everything
A launched mobile app beta for screenshots, recording, green screen reactions, and fast posting workflows.
SchoolStarted
A practical homeschool operating system for families who want structure without bureaucracy.
JimBondy
Personal loan tracking for friends and family: simple records, healthy relationships, less awkwardness.
Build in public. Teach what is changing.
I also create tech and AI content as @cto.dave, showing the tools, workflows, and product decisions behind modern software builds. If your product needs a technical operator who can also explain the future clearly, that is part of the offer.
