SOFTWARE ENGINEER · BRAZIL / REMOTE

Lucas
Gonçalves.

I build software that
makes it to production.

From full-stack products and backend systems to AI agents. I work across the stack, close to the product and the people using it.Explore my work ↓

01 / SELECTED EXPERIENCE

Real products.
Real constraints.

Selected work from teams I've been part of, from early product discovery to systems at scale.

01

KINTER.AI
Oct 2025 — Present

APPLIED AI / 0 → 1

AI agents for
accounting teams.

I own the pipeline from LLM-based document extraction to deduplication and worker orchestration. Working directly with design partners, I helped turn early feedback into product iterations and contributed to landing the first paying customer.

  • AgentCore
  • LLM orchestration

From the initial idea
to early customers.

LA MODA
Oct 2024 — Oct 2025

COMMERCE / DELIVERY

A B2B launch.
A faster path to ship.

I led delivery of a B2B commerce solution under a one-month deadline, built its CI/CD pipeline, and led the move to a TypeScript-based React codebase. I also improved caching and hardened application security.

  • React
  • TypeScript
  • VTEX
  • CI/CD
~70%

Reduction in
deployment time.

ZAK
Apr 2022 — Dec 2023

FULL STACK / CLOUD

Software behind
400+ restaurants.

I developed and maintained restaurant management tools and dashboards, contributed to the Zak Pay credit product, and optimized infrastructure for cost efficiency and scalability.

  • React
  • Node.js
  • AWS
  • Kubernetes
  • Kafka
33.5%

Reduction in
AWS costs.

RW3 TECNOLOGIA
Apr 2021 — Mar 2022

MOBILE / PUBLIC SERVICES

Public services.
In people's hands.

I built and maintained three iOS and Android apps for digital-government services in Mato Grosso, delivering mobile and backend features with React Native, Node.js and REST APIs.

  • React Native
  • Node.js
  • REST APIs
500K+

Combined downloads
across three apps.

02 / HOW I WORK

Across the stack.
Close to the problem.

I'm a software engineer based in Brazil with 5+ years of experience building production systems. My work spans web and mobile applications, backend services, cloud infrastructure and, most recently, AI agents.

I enjoy taking a product from an early idea to something people can use: understanding the problem, making technical decisions, shipping, and improving it with feedback.

I'm interested in software engineering opportunities where I can own meaningful work, collaborate with the team, and stay close to the product.
