I'm David Billiot, founder of RESILIENCE Agentic Solutions. Senior engineering, built to endure. Based in Miami and Abu Dhabi, working with clients and collaborators worldwide. Available for contract work.
I build custom software, web apps and AI agents, and I contribute to open-source projects across AI, developer tools and blockchain. Security is part of the build from day one.

- Custom software: internal tools, APIs and integrations, plus audits of apps already in production.
- Web and mobile apps: product sites and customer apps, maintained by the engineer who built them.
- AI agents and automation: agents for support, bookings and the repeated work on a shift.
- Security reviews: exposure reports and assurance for sites, software and agents already live. Testing starts only after the scope is signed.
- Personal data removal: people-search listings taken down, with a written record of where a name was found.
- Detail you can feel: I hold every screen to a premium standard. Spacing, wording, color and layout have to work together, and I catch the scroll jitter, blur and layout shift most people never see.
