Monterrey, Mexico · Product engineer / app developer / founder

I build the whole thing.Then I obsess over the details.

I move between code, product, data and design because the best products do not experience those disciplines separately. I build the system, then refine the moments people actually feel.

Where the range becomes useful

Four doors.
One operating system.

I am not trying to look like four different candidates. The same work shows up from different angles depending on the team: ship the app, design the product, build the data layer, or connect all three.

The repo is part
of the interview.

These are not companies and I do not present them as startups. I built them in public so the architecture, trade-offs and technical depth are inspectable: realtime mobile systems, decision intelligence, distributed transfer, human-centered product design and cloud infrastructure.

03 / Point of view

Design is not a layer.
It is the system.

I work where engineering, product, design and data overlap. The goal is not to collect job titles. The goal is to make the product feel intentional all the way from the database policy to the first animation a user sees.

05 / Selected work

Products, not mockups.

The visual system changes, but the pattern stays the same: define the problem, design the experience, build the software, connect the data, test the edges and ship the story.

06 / Capability map

App developer.
Product thinker.
Data-aware builder.

My center is software and product engineering. The range is useful because production problems do not respect job-title boundaries: data affects UX, architecture shapes speed, security changes flows, and product decisions determine whether the system deserves to exist.

Engineering

Apps & systems

Production-minded mobile and web development with attention to architecture, resilience, security and the ugly edge cases behind polished UI.

  • Flutter / Dart
  • Swift / SwiftUI / UIKit / Combine
  • Vue.js / JavaScript / HTML / CSS
  • Docker / Bash / AWS
Design

UI / UX & product

Interface design as a behavior system: hierarchy, motion, accessibility, segmentation, feedback and user flows — not just pretty screens.

  • Design systems
  • Interaction & motion
  • Accessibility / sensory considerations
  • Benchmarking & product strategy
Data

SQL & analytics

Data work that lives inside products, from relational schemas and row-level security to exploratory analysis and predictive-model prototypes.

  • PostgreSQL / Supabase
  • SQL + RLS policies
  • Python
  • EDA / regression / hypothesis validation
Founder mode

2026 · First place

Accessible App & Tech Showcase.

Thinki received 1st place under external evaluation with recognition from Tecmilenio, Enactus and the Secretaría de Igualdad e Inclusión de Nuevo León. The work was validated in a real community setting rather than only as a classroom prototype.
