DANIELGR is Daniel García's engineering studio. We build custom ERPs with built-in AI — your company's operating system — plus fintech platforms and digital products, end to end.
Teams and brands that trust the studio
Spreadsheets, WhatsApp, paper and three tools that don't talk to each other. We replace them with an ERP shaped around how you actually work: job sites, technicians, payroll, stock, gigs or invoices, with AI doing the repetitive work and data that stays yours.

Technicians on the road, install reports the client signs from a link, time tracking, vehicles and inspections, stock and invoicing.

Your operation the way it actually runs: payroll, job sites, technicians, stock, invoices and reports.
Agents that classify, extract and decide with traceability and human review. Models in the cloud or on your own GPUs.
Microservices, queues and data that hold up under growth. Legacy integration without stopping the business.
Exchanges, wallets and live dashboards where latency and security are non-negotiable.
Fast, accessible interfaces with character. From a landing page to 3D experiences.
Fractional Tech Lead: architecture review, CI/CD, conventions and a team that ships without friction.
We understand the business before the code: processes, data, bottlenecks.
→ Problem map
Clear, written decisions: what to build, what to buy and what not to do.
→ Technical proposal & plan
Weekly releases on a real environment. You see progress, not reports.
→ Working product
Deployment, observability and maintenance. We stay when others leave.
→ Support & evolution
I started out maintaining aircraft, where a failure isn't a bug: it's an incident. That discipline is in everything I build.
Today I lead engineering teams, design AI architectures and run DANIELGR, a studio that is small on purpose: you talk to the person writing the code.
Technical lead on an AI-powered microservices platform.
Full-stack architecture, AI and microservices for film production.
Custom AI-powered ERPs, digital product and web studio.
Backend APIs and services.
