Industrial Automation Engineer and Full Stack Developer from Bogotá, Colombia. For five years I've been building enterprise software: microservices, APIs and web applications designed to scale, stay available and be easy to maintain.
Outside of work, I build robots. Mobile platforms and robotic arms with ROS 2, taken from simulation to real hardware, plus a bit of electronics along the way.
What I work on
- Enterprise web applications and microservices, from architecture to deployment
- Autonomous robots with ROS 2: SLAM, navigation, kinematics and computer vision
- Digital chip design in Verilog, electronics and embedded systems
- Open source and educational technology with Semillero Robótica Utadeo
🔭 Currently: adding visual SLAM to Axioma with a ZED 2i and RTAB-Map
💬 Ask me about: ROS 2, SLAM, microservices, .NET, React

Autonomous mobile robot for industrial logistics 4WD skid-steer robot running SLAM Toolbox, AMCL and Nav2. Its SLAM map scores 99.8/100 against the real floor plan in Gazebo, and it is now getting RGB-D visual SLAM with a ZED 2i.
|
Camera-only perception on a Jetson Nano Visual SLAM with a single stereo camera: no wheel encoders, no LiDAR, no GNSS. On a 49 m loop, RTAB-Map's loop closure brought the drift down from 1.06 m to 6 mm.

|
Autonomous university logistics robot Omnidirectional electric robot for indoor logistics at Universidad Jorge Tadeo Lozano, with three steering modes (Ackermann, omnidirectional, crab), Nav2, real-time SLAM and LiDAR perception.
|
5-DOF desktop manipulator A small robotic arm built to hold a tattoo pen. It turns an image into a toolpath, solves the inverse kinematics and draws it in Gazebo, backed by a full kinematic and dynamic model.
|
|
Open-source 8-bit microcontroller in Verilog Binary-compatible with the ATmega328P and designed entirely with open-source tools. Every block is verified against independent oracles, and it synthesizes and meets timing on a Lattice ECP5 FPGA. Sky130 tape-out is on the roadmap.

National carbon capture and emissions map Interactive geospatial platform to map and analyze carbon balance across Colombia, with AI-assisted analysis. Built with Colectivo Hagamos.

Thanks for stopping by. Always happy to talk about software, robots or chips.
