Joaquín Minatel — Backend Developer

About me

The short version

Backend developer from Buenos Aires, 21. I specialize in designing and building REST APIs, microservices, and data pipelines. I work with Go and Python as my main tools, and I'm comfortable with the whole surrounding ecosystem: databases, containers, CI/CD, observability.

How it all started

I started at 14 with HTML, CSS, and JS. Classic. But I quickly realized that logic was my thing, not pixels. I moved to Python and never looked back.

Since then I've been self-taught: videos, official docs, courses, X (twitter), Hack The Box for cybersecurity. Always learning out of curiosity, not obligation.

Professional journey

My first job was at Dentsu as a Service Operations Analyst (2023, age 18). I started with technical support: hardware, servers, databases, Azure, tickets.

A year in, my role evolved. I started building full-stack solutions for different teams. A centralized ad management app reduced a team of 30's workload by 90%.

In parallel, I've been working independently since 2021, building software and consulting for companies that need to optimize processes.

Beyond the code

I'm quite into Bitcoin and blockchain. I'm interested in finance, the stock market, and have been following BTC for years. I'm also a big F1 fan.

I'm studying a software programming degree at UTN (2024-2027). Before that I spent a year at UP studying AI Engineering, where I took math and statistics courses.

Experience

Where I've been and what I did

Full-stack application development for internal teams: advertising, finance, operations.

Centralized ad management app with ~30 active users. Reduced the team's hourly workload by 90%.

Finance to ERP: pipeline that processes PDFs with OCR + LLMs (OpenAI/Gemini) to structure data and upload it to the ERP automatically.

Stack: Go, Python, NextJS, PostgreSQL, Redis, RabbitMQ, Docker, K8s, GitHub Actions, Azure.

General technical support: hardware, users, inventories, servers, Azure AD.

Queries and updates on production databases.

Report automation with Excel/scripts for different teams.

Ticket management, SLAs, and coordination with teams across different regions.

API and microservice development for various clients.

Technical consulting: architecture, stack selection, best practices.

Varied projects: integrations, automations, dashboards with data from external APIs (Spotify, YouTube).
