Twelve years shipping
production software.

One of Mexico's largest logistics operators. Thousands of trucks, hundreds of field crews, zero tolerance for downtime.

Field crews were still using paper and radio to coordinate loads. Dispatch was reactive. Managers had no real-time visibility into fleet location or delivery status.

Built a React Native ecosystem for drivers and supervisors. Designed Fastify backends that handle enterprise-scale GPS and delivery events. Established CI/CD pipelines that deploy to Ubuntu servers without human intervention.

Dispatch became proactive. Managers could reroute trucks in real time. Manual processes that took hours now update in seconds.

Clients who need working software, not presentations. Startups, SMEs, and internal tools for teams that outgrew spreadsheets.

Most vendors sell roadmaps. Clients needed someone who could own the entire lifecycle — architecture, code, deployment, maintenance — without a team of ten.

Operated as a one-person engineering team. Designed full-stack architectures from scratch. Implemented REST APIs consumed by web and mobile clients. Integrated legacy systems like VICIdial into modern CRM workflows. Built CI/CD from day one so shipping was never an event.

Every project shipped. Some became the core revenue system of the client. Others replaced processes that had been manual for a decade.

An education platform used by schools and parents. The previous team had left the codebase unstable and the ratings were catastrophic.

The app had a 2.4-star rating. Push notifications failed. Performance was unacceptable on mid-range Android devices. Users were uninstalling.

Rebuilt critical navigation and sync paths. Implemented a reliable push notification pipeline. Stabilized the React Native codebase. Profiled and eliminated frame drops on low-end hardware.

App store rating climbed from 2.4 to 4.3. Uninstall rate dropped. Support tickets related to crashes decreased by 80%.

Offshore oil rigs in the Gulf of Mexico. No Wi-Fi. No 4G. Harsh environments. Safety-critical operations.

Field teams could not access operational data while offshore. Every form, inspection, and safety check had to be done on paper and transcribed later. Errors were frequent and dangerous.

Built offline-first mobile and desktop applications with React Native and Electron. Designed a sync engine that queues work locally and pushes massive datasets when the device returns to connectivity range.

500+ workers accessed critical operational data daily. Inspections became digital. Errors dropped. Sync happened automatically when crews returned to port.
