Void
Technical leadership across esports web, mobile, backend, and real-time delivery at Void.
About
I lead engineering teams, architect resilient systems, and build tools that empower developers.
I'm Santiago Molina, a full-stack engineer and tech lead based in Medellín, Colombia. Over the last 12+ years I've shipped products across commerce, SaaS, gaming, and real estate — working across the entire stack from architecture and backend services to CI/CD pipelines and developer tooling.
Right now my focus is on teams and systems: how to structure engineering organizations so they stay fast to ship, easy to maintain, and hard to break. I care deeply about developer experience — not as a buzzword, but as the measurable gap between a team that ships with confidence and one that ships with anxiety. Automation is usually how you close that gap.
I've led cross-functional teams of up to 14 people spanning product, design, frontend, and backend. I believe the most valuable thing a tech lead does is reduce the number of decisions engineers have to make under pressure — through clear standards, good tooling, and systems that fail loudly instead of silently.
Outside work I co-organize ReactJS Colombia, write about engineering workflows and DX, and find the intersection between good software and good products. When I'm not at a keyboard I'm probably reading, hiking, or watching something with a good score on Letterboxd.

Principles
What I believe about engineering.
A few things that shape how I work, how I lead, and what I focus on.
01
Automate the friction, not the thinking
The best automation removes toil — repetitive, low-judgment work that slows teams down. It should never replace the thinking that makes products worth building.
02
DX is UX for your team
The developer experience of a codebase shapes how fast and confidently the team can move. Bad DX compounds. Good DX compounds too — invest early and measure it.
03
Leadership means fewer decisions under pressure
A good tech lead reduces ambiguity before it becomes risk. Clear standards, good tooling, and systems that fail loudly are how you protect a team's velocity at scale.
04
Performance is a product decision
Speed isn't a tech concern, it's a user concern. Every kilobyte and every render-blocking resource is a choice that affects real people on real connections.
05
Boring tech is often the right call
The goal is to solve the problem, not to use the newest tool. Stable, well-understood solutions let the team focus on the actual product.
06
Consistency beats perfection
A consistent codebase with some imperfections beats an inconsistent one with pockets of brilliance. Conventions compound. Exceptions cost.
