Every project, one place.

A white-label Flutter app for iENTC — a Mexican telecom operator with 500+ employees — that puts inventory and transfer-order operations in every field and warehouse worker's pocket: two branded apps from one codebase, 77+ screens of multi-step workflows, and on-site capture (signatures, photos, maps).

The customer app for a Mexican fiber ISP — one white-label Flutter app (shipped as both Mexanet and Lulunet) where subscribers pay bills with Stripe, recharge and buy plans, and manage their home WiFi from their phone.

A Flutter app built for a AAA global brand — one place for the company to reach and train its field workforce: on-demand video, live streaming (AWS IVS), dynamic surveys, a chatbot, and tool/uniform/PPE requests. I was the sole mobile developer on a cross-functional team.

A serverless, event-driven notification system for a fiber ISP that reminds prepaid subscribers to recharge before their internet package expires — a scheduled AWS Lambda that scans active contracts, applies tiered reminder rules, and pushes multichannel notifications.

A serverless push-notification microservice for a fiber ISP's mobile app — a containerized FastAPI service on AWS Lambda that registers devices, manages subscriptions, and fans out individual and broadcast push notifications through Amazon SNS. Other backend systems call it to reach customers. I built the service end to end, on the platform's existing API Gateway and database cluster.

A serverless, event-driven pipeline for a fiber ISP: KML map files describing distributor coverage zones land in Amazon S3, an AWS Lambda parses each one into structured zone records on upload, and a FastAPI service exposes them for lookup. I built the processing side — from the S3 event onward — and the same shape was later reused for other file processes.

The REST API layer behind a fiber ISP's platform — CRUD endpoints across several FastAPI services running serverlessly on AWS Lambda behind API Gateway, backed by Amazon DocumentDB, organized in a clean, consistent layered structure.

A serverless backend I built for a mobile app at a fiber-optic ISP: a FastAPI service that manages contacts (CRUD) and delivers push and VoIP notifications to the app (APNs + Firebase), with Cognito authentication and a per-user security model — running on AWS Lambda and connected into the platform's existing API Gateway and database cluster.

Online pharmacy app (Fesa) I was brought into as a specialist: the team was stuck on a map bug where coordinates sometimes resolved to inconsistent addresses. I debugged it, refactored the app's fragmented map implementations into one reliable path, and handled role-based views for doctors and regular buyers.

A lean-manufacturing mobile app (VAM) built at Voth for an industrial client — a plant-floor toolkit for continuous-improvement teams to run value-added analyses, 5S audits, and H&SE / TPM checks, then chart the results and export them to PDF and Excel. I was the sole mobile developer.

A mental-health app, launched internationally, where people log how they feel through guided emotion selectors, journal daily, and watch their emotional patterns emerge over time in charts.

A corporate site-security app — QR-based visitor control, visitor tracking, guard rounds, real-time location, and an admin panel. It was also my first Flutter project: I built features on it as an intern at Nos Imperii, mentored by the CTO, right as the team adopted Flutter.

Seycel is a nationwide Mexican platform that lets small shops sell electronic top-ups, pay 130+ services, and sell e-pins. Its Flutter app wasn't working properly, so the client hired a redesign plus new features — including single-session protection — over a SOAP web-service API.
