About

Andrew Figueiredo

I came into software engineering through quality and automation, which gave me a complete reading of how a system is built, where it breaks and what it takes to keep it running in production.

Today I build web applications, integrate AI solutions and automate processes. These are three layers of the same work: building the system, embedding intelligence in it and automating the operation around it.

My background is in Computational Mathematics, with a degree in Data Science and a master’s in Information Technology researching AI applied to Software Engineering.

Services

Systems Development

  • Custom web applications (React / Next.js)
  • APIs and system integrations
  • Landing pages and professional websites

Projects

Fullstack2025

Technical tracking dashboard

Consolidates quality indicators previously scattered across spreadsheets into a single view for the team.

  • Next.js
  • TypeScript
  • PostgreSQL
Fullstack2024

Legacy system integration

Syncs records between two systems that could not talk to each other, ending daily manual re-entry.

  • Node.js
  • APIs REST
  • Docker
Fullstack2024

Service management application

Replaces spreadsheet control with a tracked flow with history and owners, making auditable what used to be lost.

  • React
  • Node.js
  • MongoDB
Fullstack2024

Data consolidation API

Exposes through a single contract data locked in three separate databases, simplifying downstream integrations.

  • Python
  • FastAPI
  • PostgreSQL
Landing Pages2026

Meu Cantinho Imóveis

Filterable property catalog with direct WhatsApp contact, so an independent agent without a digital presence stops losing leads to competitors.

  • Next.js
  • TypeScript
  • Tailwind CSS

Landing Pages2024

Campaign capture page

Concentrates campaign traffic into a single contact flow, making return on investment measurable.

  • Next.js
  • Tailwind CSS

How I work

  1. 01

    Requirements gathering and analysis

    Understanding the actual process before proposing a solution, including what exists and what cannot break.

  2. 02

    Architecture and modeling

    Defining boundaries, contracts between components and the data model before the first line of code.

  3. 03

    Development

    Incremental implementation, with verifiable deliveries instead of a single milestone at the end.

  4. 04

    Quality, automated testing and CI/CD

    Automated suites wired into the pipeline, static analysis and gates that keep regressions out of production.

  5. 05

    Deployment, monitoring and evolution

    Automated releases, tracking behaviour in production and continuous adjustment.
