Software built end to end,
with AI that does real work.

Senior Full Stack Engineer · Tech Lead · Applied AI

I'm Giovanny González. For 13 years I've built complete products: the interface, the services, the database and the infrastructure they run on. I help you launch, clean up or scale your software, and connect your systems to AI assistants. Based in Colombia, with full overlap with US business hours.

Services

Six concrete ways I can help your company or product. Pick one or combine them.

01

Applied AI for your business

I connect your systems to AI assistants so your team can query and operate them in plain language. MCP servers, tool-using agents and search over your documents (RAG), with cost and latency under control.

  • MCP
  • Agents
  • LLM APIs
  • RAG
  • pgvector
  • Evals
02

SaaS and custom web products

From MVP to a platform in production: API, web app or PWA, database and admin panel. Architecture designed to grow without a rewrite.

  • React
  • Next.js
  • Vue 3
  • Node.js
  • Go
  • PostgreSQL
03

DevOps and deployment

Containers, CI/CD, servers and cloud. I leave your system deploying itself, with TLS, retries, backups and monitoring.

  • Docker
  • Kubernetes
  • GitHub Actions
  • Terraform
  • AWS
  • Azure
04

Technical leadership

A tech lead for your team: I set the architecture, review the code, define standards and plan the work. Ideal when you have developers but lack technical direction.

  • Architecture
  • Code review
  • Clean Architecture
  • SCRUM
05

Internal tools and automation

Management apps that replace spreadsheets and manual processes: reports, approval flows, integrations between systems. For companies and public agencies.

  • Laravel
  • C# / .NET
  • Integrations
  • Reporting
06

Team training

Hands-on workshops for your team on applied AI, Docker and containers, virtualization and modern web development. 4+ years teaching at SENA and university level.

  • AI
  • Docker
  • Virtualization
  • Web development

Work

Real work, running in production.

An internal API you can query in plain language

At one of the largest accounting and business software platforms in Latin America, I built an MCP server in C# that exposes an internal API as tools for AI assistants. What used to be reachable only through code is now queried in plain language.

  • Azure

A complete SaaS platform, designed and led from scratch

I designed the whole platform and lead its team technically: AdonisJS API with PostgreSQL and Redis, Vue 3 PWA, all containerized with Docker and shipped through GitHub Actions against a private image registry, with reverse proxy and automatic TLS.

Academic scheduling without spreadsheets

I built and maintain the training center's academic scheduling system, in production since 2024. It generates the per-instructor hour and competency reports that used to be assembled by hand, alongside an enrollment capture and consolidation tool.

How I work

  1. 01

    Discovery

    A call to understand the problem, the business and what already exists.

  2. 02

    Proposal

    Scope, architecture, timeline and price in writing. You know what you get before we start.

  3. 03

    Build

    Short iterations and frequent demos. You see real progress every week, not just at the end.

  4. 04

    Production

    Deployment, documentation and support. I deliver working software, not just code.

Personal assistant

I run a private productivity tool for strictly personal use. It is not a product, it is not open to the public and it does not process third-party data. The terms under which it operates are published in the Privacy Policy and the Terms of Service (in Spanish).
