I lead a team of eight building automation platforms, backends and LLM-assisted workflows — turning repetitive operations into systems that run themselves, at a cost that holds as they scale.

01 / ABOUT

Engineer.

I'm a Computer Systems Engineer from Torreón, Coahuila, working at the intersection of RPA, backend development and intelligent process automation. I started writing production code as a programming technician in high school, spent four years on a competitive robotics team, and turned both into a career building systems companies actually run on.

Today I'm Head of Engineering at Botbi, leading a team of eight RPA and web developers. I own the technical standards, the solution architecture and the documentation across several concurrent projects — Solution Design Documents going in, Technical Design Documents coming out — and I still build hands-on when a project needs it. I got there by shipping: junior developer to RPA developer to leading the practice in about a year.

I like problems with hard constraints: competitive programming taught me to reason about correctness and complexity before touching a keyboard — a habit that shows up in every system I design.

The track record.

Mar 2026 — Present

Head of Engineering

Botbi
  • Lead a team of 8 RPA and web developers, enforcing internal technical standards across every deliverable — and still building hands-on when a project needs it.
  • Plan and document the architecture of upcoming work through Solution Design Documents: current-state analysis, realistic automation scope, goals and traceability, phases, requirements and stack selection.
  • Review and validate the final Technical Design Documents so several concurrent projects ship to the same standard.
  • Partner with the Project Manager to keep Agile applied correctly across the engineering team.
  • Design and build prototype software for internal company use.

RPA Developer

Botbi
  • Built and maintained attended and unattended automations with Automation Anywhere A360 and Python across HR, Accounting, Inventory Management and Audit.
  • Shipped a multi-model LLM architecture (Qwen + OpenAI) for automated invoicing that routes low-complexity reasoning to a cheaper model to cut operating cost — with a sensitive-data masking layer that guarantees no private information ever reaches an external LLM.
  • Built an automated change-control collector across developments on the Automation Anywhere platform, guaranteeing correct versioning and cutting the Project Manager's turnaround time.
  • Designed internal automation services in Python (Flask, Selenium) to make ongoing development traceable.
  • Led and supported junior developers through functional testing and code review under Agile.

Junior Developer

Botbi
  • Built a Laravel platform for an industrial footwear company, wiring up workflows and several external logistics APIs for order-status visibility — order processing time down 50%.
  • Developed automations with Automation Anywhere and Python for the accounting area of a meat-processing group, eliminating manual error and accelerating the workflow.
  • Designed Qlik dashboards for the finance area of a hydrocarbon company, turning raw data into decisions.
  • Applied Selenium to automate functional testing of internal platforms.

Research Collaborator — Computer Vision

Behavioral Physiology Laboratory · UNAM
  • Built a video-based recognition and tracking system for laboratory rats in Python and OpenCV for the Department of Physiology, School of Medicine.
  • Automated the extraction and statistical analysis of behavioral-experiment data that had previously been scored by hand.

Programming Advisor & Mentor

Samurai Code · FRC Robotics
  • Volunteer programming mentor for high-school students in a competitive FIRST Robotics Competition team — my ongoing community work.
  • Programming advisor 2022–2025: computer vision with Python and OpenCV, and advanced robot control systems in Java and Python.
  • Plan the technical season: robot codebase architecture, code standards and hands-on training for new programmers.

03 / SELECTED WORK

What I've built.

Botbi · AI Engineering01

Multi-model LLM invoicing

An automated invoicing pipeline built on two models instead of one: low-complexity reasoning is routed to a cheap model (Qwen) and only the hard cases reach OpenAI, so the cost curve stays flat as volume grows. In front of both sits a sensitive-data masking layer — client information is stripped before anything leaves the building, so no private data ever reaches an external LLM.

Pynbot

Low-code automation platform built in Python and C#. I contributed to core development — the layer that lets non-technical users assemble their own workflows.

AI-assisted engineering

I use Claude as an actual agent in the delivery process, building and training custom skills that standardize how documentation gets written and speed up development — so the SDD/TDD standard I set as Head of Engineering scales without becoming paperwork.

Botbi · Platform04

Reusable automation core

Internal Python/Flask services that turned one-off bots into a shared platform, plus an automated change-control collector across every development on Automation Anywhere — correct versioning without anyone chasing it, and a much shorter turnaround for the Project Manager.

Logistics visibility platform

Laravel platform for an industrial footwear company, integrating several external carrier APIs so order status is visible in real time and accuracy is fixed at the source.

Rat tracking for neuroscience

A video-based recognition and tracking system in Python and OpenCV for the Behavioral Physiology Lab at UNAM's School of Medicine — replacing hand-scored behavioral experiments with automated data extraction and statistical analysis.

Invitta Studio

Web platform for designing and distributing digital event invitations, with RSVP and QR access — guest management becomes data instead of phone calls.

FRC vision & control

Computer vision in Python + OpenCV for target detection, and control systems in Java for a robot that has to work on the first try, in front of a crowd, with no rollback.

Mandelbrot shader

Fractals are a personal obsession of mine, so I made one the backdrop of this whole page rather than picking a stock gradient. It is a real-time Mandelbrot↔Julia field: a single full-screen quad, GLSL fragment shader, smooth iteration coloring, IQ cosine palette, distance-estimator neon edges, bloom and chromatic aberration — with an endless self-similar zoom loop and an adaptive iteration budget that holds 60 FPS.
