SANTIAGO GÓMEZ ACERO / FULL-STACK DEVELOPER
I design and build AI products, mobile apps and software that works even offline.
01 /
AI products, offline software and complete systems: context, architecture and technical decisions.
01 — 2026
From PDF to personal reading: reconstructed text, OCR and speech, completely offline.
02 — 2025 — 2026
A platform that launches digital ad campaigns on Tonic, Meta and TikTok with AI-generated content — from hours to minutes.
🔒 Client project · private repo

Sites, tools and experiments that also tell the story.
Habits and mood in native apps. Local writes, outbox synchronization and compatibility tests between iOS and Android. In development.
PDF and EPUB with Kotlin and Jetpack Compose, local speech, backups and atomic persistence. Independent product in development; not yet on Google Play.
Academic logistics MVP: Flutter app, OR-Tools optimization and incident-driven rerouting with local fallback. Evaluation across 30 simulated scenarios.
Personal finance PWA with accounts, transactions, reports and JSON backups. Local IndexedDB data, with no backend or sign-in.
Football career simulator with a deterministic engine, versioned saves, minigames and code-generated pixel art. Personal project.
Work management with Kanban, sprints, integrated Daily and Team Health modules, analytics and gamification.
Multi-tournament platform with invitation-based private leagues, predictions locked at kickoff and idempotent SQL scoring.
Commercial lead-capture site that contributed to selling 4 of 16 lots in a country-side residential project.
Institutional site with its own design system and a narrative landing where hand-drawn illustrations morph into real photography (GSAP).
Institutional site for a rural association in Colombia: 400+ active users in the first months.

The stacks I work with every day.
Award-winning public speaker (ULIBRO 2019) and recognized developer at IngenioTIC 2022. I lead projects end to end: gathering requirements with non-technical stakeholders, communicating decisions clearly and delivering under pressure. English B2.2 — comfortable in international teams.
04 /
I don't just build AI products — I build with AI. Coding agents, a multi-model ecosystem and open-source models are part of my everyday toolbox.
Claude Code and Codex as pair programmers: I direct agents that write, test and refactor under my judgement. They multiply delivery speed without sacrificing quality — every line goes through my review.

Claude, GPT, Gemini: every task has its ideal model depending on reasoning, multimodality, context window and cost. Knowing how to choose is part of the craft.
claude · gpt · gemini
Llama, Whisper and local models via Ollama when the case demands data sovereignty or zero cost per token. AI does not always live behind a paid API.

What I learn using these tools becomes features: generation pipelines, agents, RAG and automations that already live in the projects above.

Client platforms: ad campaigns generated with multimodal AI and an English coach with real-time voice conversation.
2026
Offline reading with local processing, atomic persistence and integration tests. Public Windows preview; Kotlin/Compose Android version in development.

Santiago Gómez Acero · Bucaramanga, CO
I'm Santiago, a full-stack developer from Bucaramanga, Colombia. I build AI platforms for clients and independent products such as Lector. My work spans web, desktop and Android: real-time voice conversations, local document processing and systems that preserve user data even offline.
I finish my Systems Engineering degree at UNAB in 2027 while building for real clients. I'm not satisfied with something merely working: I'm obsessed with it delivering results — real users, metrics and measurable quality. If you have an idea you want to turn into reality, let's talk.
