Gabriel Sassaki

Hi! I'm Gabriel. I’m a full-stack developer who believes that great software is built on two things: clean, maintainable code and crystal-clear communication. I don’t just "write code" — I help businesses and entrepreneurs turn their ideas into functional, fast, and reliable digital products.

Whether you're looking to launch a fast-loading landing page or need a medium-sized custom system to manage your data, I treat every project with the same level of technical rigor and attention to detail.

What I Can Build for You:

Performance-First Websites: High-converting landing pages and business sites built with Next.js and Tailwind CSS.

Custom Web Applications: Robust back-ends using Node.js (NestJS) and PostgreSQL to handle your business logic and data securely.

Real-time Features: Integration of WebSockets for live updates, chat systems, or interactive dashboards.

Smart Automations: Need to connect different APIs or automate a manual task? I specialize in creating tools that save you time.

Modernizing Legacy Code: Helping you transition from older setups to modern, scalable TypeScript architectures.

Why Work With Me?

Fluent English & US Time-Zone Friendly: I’m based in Brazil (UTC-3), which allows for great overlap with North American and European business hours.

Clean Architecture: I’m currently pursuing JSE and OpenJS certifications, which means I follow industry-standard best practices. No "spaghetti code" here.

Ownership: I don’t just deliver and disappear. I provide documentation and support to ensure you actually know how to use and scale what we’ve built together.

Tech Stack:

Frontend: React, Next.js, Tailwind CSS, TypeScript.

Backend: Node.js, NestJS, Express.

Database: PostgreSQL, MongoDB, Prisma/TypeORM.

Extras: WebSockets, REST APIs, Git, Docker.
