Tiago Fernandes

I'm a Senior Product Engineer at Enginy, in Barcelona. Over 13+ years — including 4 as a Tech Lead — I've built product-focused web platforms across B2B SaaS, fintech, online healthcare, e-commerce and gaming.

I'm a generalist engineer with a product focus: I invest in practices, methodologies and design patterns over the specifics of any one language. The right tool for the job depends more on what an organisation needs and already knows than on what's newest or fastest.

I've been working on cross-functional teams (PO, Designers, Engineers, QA, Data, Marketing, Legal) where I help design technical solutions that help us reach our goals as a company.

I've been on call since 2018, from first responder to owning the fix, and I hold delivered code to the standard that it shouldn't wake anyone up at night. I hold strong technical opinions and drop them readily when the scale or the problem turns out to be different — in disagreement I'd rather stay transparent than become a blocker.

I've worked with a myriad of methodologies, architectures, and technologies. Such as:

• kanban
• lean
• scrum
• bdd

• microservices
• serverless
• event sourcing
• cqrs
• domain driven design
• hexagonal architecture

• nodejs / javascript / typescript
• serverless
• reactjs
• vuejs
• nextjs
• nuxtjs
• nestjs
• temporal.io
• playwright
• php
• mysql
• postgresql
• mongodb
• kafka
• graphql

• jenkins / groovy
• circleci
• docker
• kubernetes
• aws services
• google compute engine services

A European citizen born in Portugal. Currently living in Barcelona.

I have a BSc and an MSc in Computer Science from Minho University (Portugal). My MSc's specialisations were Artificial Intelligence and Cryptography. My dissertation's subject was weak secret key-agreement protocols.

I volunteer at Babel Punto de Encuentro as developer, a small but energetic Barcelona based NGO. They run a school in Senegal's capital Dakar, and do some great community work in Barcelona as well, providing counselling and psychological help to people who are in a vulnerable situation.
