Project: carterapp — offline-first personal finance app (carterapp.com.mx)

• – Designed and built carterapp, a personal finance PWA for Mexico: log an expense in three taps, in Spanish or English, with MXN and USD kept side by side.
• – Designed an offline-first sync model — records are written to the device first and synced with device-minted IDs, so entry never waits for the network and sync is idempotent.
• – Enforced data integrity in the database itself: composite foreign keys keep every transaction in its account's currency and its category's type.
• – Built monthly budgets, a card cut-off and payment calendar, a month-end balance projection, and the backend for subscriptions and push notifications.

Project: Mi 70-20-10 — leadership coaching platform for eQual Business Solutions

• – Designed and built a coaching platform where participants, coaches, and admins run a leadership-development program end to end.
• – Secured the data with Postgres row-level security per role, so each user sees exactly what their role allows and roles can't be changed from the client.
• – Built AI-assisted rubric evaluation of submissions, an AI coach chat, and retrieval over the program's material, with coaches approving what is released.
• – Extracted a reusable React component library and automated deploys for the app and its backend functions.

Project: API backend abstraction to migrate a legal reporting system to a newer platform version

• – Designing C++ features for an API backend abstraction layer that lets a legal reporting system migrate to its new platform version without breaking existing clients.
• – Defining clean interfaces between the legacy C++ core and the new API so features can move over incrementally.
• – Implementing new features and fixing defects through root cause analysis, working with beta users and QA.
• – Integrating AI-assisted features into the backend and tuning them for response time and cost.

Project: Amazon Fire TV next generation — porting a third-party video streaming app to new devices and Amazon's new non-Android OS

• – Ported a major third-party video streaming app to Amazon's next-generation Fire TV devices, working in the middleware layer.
• – Adapted Google's Cobalt application runtime to the new device hardware and to Amazon's new operating system, which is not based on Android.
• – Implemented features and fixed defects through root cause analysis, working with beta users and test teams.
• – Coordinated with partner engineering teams to route and escalate issues outside the project's scope.

Project: Test environment to automate embedded-system release processes for an engineering-services provider

• – Refactored a key desktop application with Python and PySimpleGUI, significantly improving readability and maintainability.
• – Strengthened the architecture by applying SOLID principles and the listener pattern, producing a more robust, understandable codebase.
• – Designed and built a project-manager feature from scratch to streamline creating and editing test profiles.

• – Analyzed and fixed defects in existing features written in C++ and WinCC OA.
• – Developed new functionality and unit tests, including keeping system status in sync with the data-queue handshake.
• – Designed and implemented DevOps infrastructure to support a new licensing model, enabling migration to a modern tech stack.
• – Built from scratch a Python 3 proof-of-concept API wrapper over crypto.com to simplify requests from higher abstraction layers — the bid was accepted.
• – Leveled up in Go, Python, API design, and systems design through company training.

• – Led the Mexico team as tech lead and developer, fixing bugs in C++ engine-testing applications.
• – Supervised 10+ engineers across 5 clients, guiding their professional and personal career paths.
• – Interviewed candidates and designed team processes to onboard new engineers during headcount growth.

Project: Antártico — order management for cold-storage spaces

• – Designed and built a web app to manage orders for cold-storage spaces, from the data model to deployment.
• – Built it on Laravel and SQL behind a login, and deployed and ran it on a DigitalOcean server.

• – Scrum Master and developer for embedded applications on 16-bit microcontrollers (C) and their GUIs (Qt C++).
• – Led the Mexico Qt C++ team troubleshooting the tractor UI — from microcontroller buffer logic to data interpretation and on-screen visualization.
• – Stood up and led a new team building simulators for the 16-bit microcontroller, the CAN bus, and virtual product interactions in C and C#.
• – Led design and implementation of a virtual Ethernet simulation supporting Ethernet on 32-bit FreeRTOS microcontrollers.
• – Reported to users and stakeholders every 2-week sprint and presented the plan for each upcoming PSI.

• – Developed Qt UI applications, frontend and backend, in C++.
• – Designed features to process data from a 16-bit microcontroller over CAN (J1939).
• – Improved code quality by fixing inconsistencies and writing unit tests with Google Test.

• – Designed and built from scratch a static code analyzer with a GUI that highlights bad coding practices, using Flex and Bison.
• – Built electronic test boxes that emulate signals and communication protocols for device testing.

• – Wrote the base code for Kinect applications to improve the classroom experience through technology.
• – Built Kinect interactions with hardware interfaces and controlled XAML apps through natural body movement in C#.
