What have I been up to?
Short version: I like building things that can prove what they claim — systems that ship with their metrics attached. Lately that means legal AI in production, machine learning on sound and images, and a steady pull back toward the physics I came from. Here's the path so far.
Founding Software Engineer · pin
Legal document intelligence in production (private demo, real users): every answer a lawyer gets is cited to the exact page of the case file. Built the engine and the full app end to end.

LATAM's leading healthtech (Dentalink · Medilink · Gerty): 8,000+ clinics, 60,000+ health professionals, 20+ countries, ~42M appointments a year, a 200+ person team. I shipped across the payments portal (backend + frontend), the online-booking app, billing and messaging APIs, new features and redesigns, plus refactors and maintenance of the core SaaS — working through code review across large teams. Stack: PHP (CodeIgniter), React, SQL.

IoT + AI systems for real-time detection of illegal logging — edge audio intelligence, cloud analytics, and instant alerts for forest rangers.
STEM Education Advisor · CNTV / Argumental Films
Sole scientific advisor for "¡Manos al experimento!" — a 13-episode children's science series filmed in seven days. Designed and validated every experiment for safety, rigor, and fun.

Engineer #2 at a B2B SaaS for environmental-law compliance (Ley REP, Chile). Helped scale from 4 to 20+ enterprise clients, improved core workflows 60%+, and took automated test coverage from 0% to 67%+.

Lawyers lose hours interrogating thousand-page scanned case files — and can't act on an answer they can't verify. pin reads the file and answers with a citation to the exact page, source image alongside.
Local-first by design: an OCR cascade feeds hybrid retrieval, nothing leaves the machine, and operating cost stays at $0. 30k+ pages ingested at ~10–100 pages/s, 98.5% recall@k50, ~2,000 automated tests.

→ let’s talk about this oneIllegal logging is heard before it's seen. talia puts solar-powered ears in the forest and turns a chainsaw into an alert a ranger receives within minutes, with audio evidence and GPS.
Edge-first: the PyTorch classifier runs on the sensor itself, LoRaWAN carries only events, and the backend triangulates the source. Every confirmed alert goes back into training.

A three-stage pipeline — faster-whisper transcription, structured Markdown, LaTeX — with every equation test-compiled before embedding, and scene detection to keep the frames worth keeping.

From raw highway footage to a mailed report: speed sentinel finds each vehicle, estimates its speed, and builds the evidence file for the violation.
YOLO/Detectron2 detection with per-vehicle tracking; speed comes from calibrated frame geometry; the output is a frame-accurate PDF report, delivered by email.

Models fine-tuned on car-POV Mapillary imagery score damage frame by frame; aggregation turns detections into an actionable list per street.

The thesis line, reopened as software: how do galaxies and planetary systems form? pleamar runs numerical experiments on gravitation — N bodies, time, patience.
Built on JAX for differentiable, GPU-ready N-body integration, equinox for structure, astropy for honest units. Made to be measured, visualized and questioned.

Autonomous coding agents hit forks a human should decide. queltehue is the sentinel that reaches you over the cheapest channel that works: a log line, a Telegram card, or a natural phone call answered hands-free.
FastAPI backend with SQLite state; channel escalation is configurable policy, not new code. Free and self-hosted by default.

→ let’s talk about this oneA damaged QR on a real ID card, brought back bit by bit. Data recovery that can prove itself.
Reed–Solomon error correction applied by hand, every recovered byte cross-verified against a second decode path — non-falsifiable by construction.
python · reed–solomon
→ let’s talk about this oneCode quality is usually argued with adjectives. concon argues with measurements: hundreds per run, against industry-standard metrics.
tree-sitter parsing across languages; complexity, coverage, duplication, hygiene, docs. Its one hard rule: a metric that cannot be computed honestly reports unknown — never a vibe.
python · tree-sitter · static analysis
→ let’s talk about this oneAn autonomous agent is only as good as the workspace it wakes up in. bootflower prepares that workspace — and proves it.
Environment, tooling and repo state laid down with byte-level verification of every artifact. It's the same system that keeps this very site's workflow in sync.

A meme with a build system: it screams "FAHH!" when a merge lands and cackles when a PR gets closed. Zero utility, maximum joy.
Git hooks wired to a soundboard; sounds and triggers configurable per repo event.

Git is the only state and GitHub Actions the only runtime — no database, no server. Delivery belongs to its sister, queltehue.

It weighs energy, mood, health and neglected areas; a deterministic engine decides and AI only narrates. Health before output — never streaks, shame or guilt.

Auth, synced video, messaging, feed, likes, profiles; the time gate smuggles in a math lesson about reading the clock — and a little Pavlov.

Three habits I can't switch off.
01Science
Astronomy taught me to distrust my own answers: measure first, quantify the uncertainty, let the data overrule me. It's why my systems ship with their metrics attached.
02Education
Teaching physics taught me that if I can't explain something simply, I don't understand it yet. That discipline carries into design docs, code review, and every conversation with a non-engineer.
03Engineering
Years across PHP, Python and TypeScript taught me that plain, well-tested code is what survives production. I write for the person who maintains it next — usually future me.
AFK
Family & friends first — happily engaged. Music, always. I make time for the outdoors; it keeps the heart happy and the head light. Also: plants, and eating well.
