I build systemsin production.

Explicit boundaries, data that does not lie, and systems you can explain.

Field notes from the build.

Notes on AI engineering, data pipelines, platform tooling, software architecture, and SEO/AEO — practical deep-dives from production applications.

When context starts working against you

An hour of Grill.me on a permissions system. I let the agent work and came back to a half-finished implementation: the context of that conversation had swollen and the original plan no longer fit. I dropped it into a file by phases, one new conversation per phase, and that is when it closed. ---

Anti-Cliché: I used to spend more time fixing than writing

I have used Cursor for a couple of years. I started on Tab. When I moved to agents, a chunk of my time went to reviewing and fixing what they generated. I built Anti-Cliché.

Knip: dead code when AI agents write faster

AI agents speed up how much code we generate. Knip helps find files, exports, and dependencies nobody uses anymore — and turn that hygiene into an automatic project rule.

Microsoft Clarity

Free session recordings and heatmaps. Clicks, scroll, rage clicks, insights. Watch the session without instrumenting events. One script. Not product analytics.

Sentry

Error tracking, performance, and tracing. Stack traces, breadcrumbs, replay. The crash report from the deploy, not the funnel. Cloud or self-host. Source getsentry/sentry.

SiteAnalyticsahrefs.com

Ahrefs

SEO crawl and index — backlinks, keywords, site audit, rank tracker, content explorer. Competitive research against a web-scale index, not your own analytics.

SiteAnalyticsPostHog/posthog

PostHog

Open-source product analytics, replay, flags, experiments, and error tracking in one stack. Cloud or self-host. Events, persons, HogQL. MIT + ee.

What I've worked with.

Not just today's stack — tools and patterns from years of projects and notes. Not a logo wall: a map of what I've used, still use, and would reach for again. Hover any entry to see the pattern behind it.

System Architecture

DDD, event-driven, legacy refactors, patterns that scale.

  • Domain-Driven Design

    Code organized by feature & domain.

  workflows/
  notifications/

  • Event-Driven

    DB triggers, queues, real-time processing.

    loc: 02.03sec: AR2
    emit('job.completed', { id, result });

  • Result / Either

    Explicit error types, no silent throws.

    loc: 03.03sec: AR3
    type Result<T> =
  | { ok: true; value: T }
  | { ok: false; error: E };

  • Microservices

    lio-api-serv-* decomposition — bridge, mailings, envíos, notifications.

    loc: 04.03sec: AR4
    // lio-api-serv-bridge
// lio-api-serv-mailings
// lio-api-serv-notifications

  • RPC-Only · Multi-Tenant

    All DB access through Postgres functions with tenant isolation.

    loc: 05.03sec: AR5
    create function get_jobs(p_org uuid)
  returns setof jobs
  language sql security definer;

  • Legacy Refactoring

    Recovering complex codebases, monolith decomposition.

    loc: 06.03sec: AR6
    // before: 1 deploy · 1 DB
// after:  api | worker | bridge

context first · rules in the repo · human review

I don't delegate thinking — I delegate implementation

I don't chase better prompts — I chase better context. The agent writes; I lock product, constraints, and patterns before a single line ships.

2016 — 2017

CoffeeCode

Co-founder & Frontend Developer

Co-founded a small studio delivering responsive websites and email-marketing campaigns compatible with major email clients — my first step from freelance frontend work into building products end to end.

First end-to-end product ownership

2017 — 2019

Synapsis CI

Frontend → Full Stack Developer

Evolved from responsive frontend sites to full-stack ownership: maintained a custom CodeIgniter CMS, shipped a multi-domain page builder with centralized visual config and cross-domain content replication, and ran GSuite plus hosting-provider services.

Libre Opción

Software Developer

Nearly three years on a single e-commerce marketplace product: migrated a performance-struggling monolith into microservices (central API, import server, task runner, payment/shipping/notification bridges), rebuilt UI/UX from scratch, and scaled from ~50 to ~1,000 concurrent users across infrastructure I built from zero.

~20× concurrent user growth

Aerolab

Software Developer

Worked with multidisciplinary teams on developing and integrating multiple products: enterprise Salesforce platform, D3.js newspaper-style chart MVP from a complex legacy refactor, i18n university CMS on Strapi, and mutual-fund calculator with GitHub Actions cron feeds and Sanity persistence. Led select builds with internal and external teams, plus formal CI/CD with ephemeral per-branch environments and contribution workflows.

Flywheel Studio

Backend Developer / Platform Engineer

I lead a workflow orchestration and notifications product while growing into team leadership: built push/email automation almost solo over ~11 months (Next.js 16 RSC, Supabase RPC-only backend, modular async engine), shipped NPM SDKs and a Firebase→relational correction — and today I mentor developers, define code starters, establish engineering standards, and run retros for the broader dev team.

About

On the work, and how I build it

Over a decade shipping products in production: from frontend to platform, Aerolab to Flywheel. Focused on product and architecture. Completing a Systems Engineering degree; production work did not wait for the diploma.

My approach: think about the product first, then choose architecture that fits. Maintainable, performant, honest code — no over-engineering, no abstractions for their own sake — just systems that solve real problems.

  • Product and architecture
