RENÉ CONTRERAS // AVAILABLE FOR BUILDS
I'm René Contreras. I build custom web applications, business systems, and automated workflows for solo founders and small business owners who need working software fast.
Using advanced AI-assisted development tools, I write, test, and ship production-ready code in a fraction of the time of traditional agencies. No account managers, no handoffs, no bloated budgets. You work directly with the developer writing your code.
No generic templates or rigid packages. I build custom software tailored exactly to your operational logic.
From landing pages and high-converting marketing funnels to complex multi-user web applications. Custom built for speed, SEO, and clear conversions.
Internal software engineered to run your daily operations without spreadsheets. Built to capture, route, and organize business data.
Cross-platform iOS and Android apps built with Flutter. Take your product concept from a basic prototype directly to the app store.
Connect your apps, route leads, scrape data, and automate repetitive tasks. I also build custom AI-assisted features directly into your systems.
Keep your software fast, secure, and updated. Get direct support, performance fixes, and security patches long after launch.
High-converting conversion pipelines engineered to turn cold traffic into qualified leads and sales. Built with automated follow-up sequences.

You talk directly to the person writing the code. No telephone game, no delayed messages, and no scope creep through middlemen.
I leverage advanced AI-assisted coding tools to write, test, and debug code in hours instead of weeks. I build at a pace traditional teams can't match.
I build using clean, standard code on modern tech stacks. You own the code, the database, and the infrastructure. No proprietary constraints.
No "digital transformation" pitches or "synergistic roadmaps". Just real, working systems built to solve your operational constraints.
