Portrait of Santiago Molina

Experience

12+

Years shipping web and mobile products across full-stack, leadership, and automation roles.

Team led

14

Largest cross-functional team I have led across product, design, frontend, and backend.

Cycle Time

-75%

Reduced release lead times by optimizing CI/CD pipelines and automating quality gates.

Community

100+

Typical attendance for ReactJS Colombia meetups, workshops, and talks.

Stack

A full-stack toolkit built around automation and DX.

React and TypeScript sit at the center, but the work extends across the full stack: backend services, automation pipelines, testing infrastructure, and delivery tooling.

A curated snapshot of the stack, ordered from the tools that shape products most directly to the supporting systems around them.

Selected work

Work shaped by real teams, real constraints, and measurable outcomes.

From headless commerce and esports to real estate and open source, these projects show how I approach architecture, automation, and delivery under real constraints.

Approach

The work is technical, but the goal is always team clarity.

The throughline in my work is making engineering calmer: clearer priorities, fewer avoidable decisions under pressure, and better systems for the people shipping them.

What I do now

Engineering that ships and systems that last.

My work spans full-stack delivery, developer tooling, and automation: finding the slowest parts of a team's workflow and replacing them with repeatable systems that make shipping feel calmer and more predictable.

How I lead

I stay close to the code, set useful standards, and help teams make better technical decisions earlier.

Outside the sprint

I co-organize ReactJS Colombia, write about DX and workflows, and keep building while working remotely from Medellin.

Beyond delivery

Speaking, community work, and the setup behind the work.

Projects only show one part of the picture. The other part is how I share what I learn, contribute to engineering communities, and keep my own workflow sharp.

Speaking and community

Practical sessions for engineers, teams, and local communities.

I am most useful in rooms where the goal is practical clarity: developer experience, technical leadership, architecture, testing, automation, and the delivery systems that make teams feel more confident.

Uses and workflow

A practical setup built around clarity and fast feedback.

The exact tools shift over time, but the priorities stay the same: boring reliability, fewer context switches, and a workflow that supports both deep implementation work and hands-on leadership.

Bias

Boring reliability over shiny setup churn

Default stack

TypeScript, React, Astro, Node.js, Tailwind, Vitest, Playwright

What I optimize for

Fast feedback loops, clear standards, and fewer context switches

Writing

Practical writing for engineers who build and lead.

I write about software architecture, full-stack systems, automation, and the engineering decisions that help teams ship with confidence. Published in Towards Dev and on Medium.
