currently building AI for sales at Salesbud

From problem to product in production.

I'm a full stack developer with a product mindset: database, API, automations and user experience, treated as one connected system. I use AI with intent at every step, from architecture to deploy, without outsourcing the technical judgment.

about me

More than code: product from start to finish.

I'm Anderson, a full stack developer based in Palhoça, Brazil, with a Computer Science background from Univali and 4+ years building product. I started out writing interfaces, and today I think about the whole product: database, API, automations, the app, and the experience that reaches the end user.

My edge isn't just knowing React, Next.js or React Native, it's being able to integrate systems, connect CRMs, automate manual processes, and turn a loose idea into something running in production. I gravitate toward projects that require understanding the business, not just implementing a screen.

I use AI as a real part of my engineering workflow, in research, architecture, code generation, refactoring, testing and documentation. That doesn't replace technical judgment: I break the problem down, define the solution, and review everything with the same rigor as always. These days that's also literally my job: at Salesbud, I build product for an AI platform applied to sales, and I use AI in the very process of building it. The responsibility for quality is still mine.

Away from the keyboard, I train almost every day. That's where I get the discipline I bring to work: consistency beats motivation. And every once in a while I trade the editor for an ESP32 on the bench, just to remember hardware is really just another kind of system to understand.

how i work

A stack built to ship the whole product.

Not a list of buzzwords, this is what I actually use to take a product from zero to production.

01

Frontend & Product

Fast, accessible interfaces with real attention to detail.

  • React
  • Next.js
  • Astro
  • TypeScript
  • Tailwind CSS
02

Backend & Data

APIs, databases and business logic that hold the product up.

  • Node.js
  • REST/GraphQL APIs
  • SQL
  • Supabase
  • PostgreSQL
03

Mobile

Shippable native apps, without reinventing the web layer.

  • React Native
  • Expo
04

Integrations & Automation

Connecting systems that don't talk to each other yet.

  • CRM integrations
  • Webhooks
  • Auth0
  • Process automation
05

AI-assisted Engineering

Copilots and agents as a real part of the flow, not a shortcut.

  • LLMs & copilots
  • Coding agents
  • Assisted refactors & tests
  • Human critical review
06

Hardware & IoT

When the product leaves the screen and becomes a device.

  • ESP32
  • Embedded prototyping
  • Sensors & physical automation
projects

Case studies, not just pretty screens.

Real projects, with a problem, a technical decision and an outcome. Even the simpler ones still say a lot about how I work.

Pague SafeCase study

Pague Safe

Landing page for a payment gateway

Problem: The client needed a sales page that conveyed immediate trust. For a financial product, any hesitation costs a conversion.

Solution: Built the landing page from scratch: visual hierarchy focused on conversion, tight copy, and performance tuned to load fast on any connection.

  • Next.js
  • Tailwind CSS
  • Vercel

Case study: original environment has no active hosting right now.

Automated Text ConverterLive

Automated Text Converter

Internal data-automation tool

Problem: A repetitive manual process: turning text from one file into another format based on a spreadsheet, operational work that shouldn't take up a person's time.

Solution: Built a web app that automates reading the spreadsheet and converting the content, removing the manual rework from the process.

  • React
  • Next.js
  • Automação de arquivos

In use: an active tool the client accesses to run the automation on demand.

Home Maintenance ServicesCase study

Home Maintenance Services

Institutional landing page for an independent contractor

Problem: A self-employed professional with no digital presence, losing referrals for lack of anywhere to send potential clients.

Solution: A lean institutional site: service overview, social proof, and a direct contact channel via phone and WhatsApp.

  • Next.js
  • Tailwind CSS

Case study: the original domain is currently offline.

Got a product to get off the ground?

If it involves integrating systems, automating something manual, or building a whole product (front, back and everything in between), I want to hear about it.
