Luiz Pansarini
Principal Software Engineer · Brazil
From IT helpdesk at Klabin to Principal Engineer in 14 years. I build the products I'd want to use — Next.js, React Native, and the messy backend that ties them together. Open to new opportunities.

About
Started in IT support at Klabin in 2012, pivoted into engineering at UAUBox in 2019. Went deep on e-commerce at scale through Corebiz/VTEX, React Native at Luizalabs (Magazine Luiza Superapp), and led the first US heavy-machinery e-commerce at Machinery Partner — from no-code to Next.js + headless CMS.
Web, mobile, and the backend that ties them together. TypeScript every day, WCAG 2.1 AA, and phones first — because that's where the people I'm building for actually open the link.
I update /now when something changes, and post on /blog when something is worth saying.

Career
Machinery Partner
Principal Software Engineer ·
- Leading the no-code → Next.js + headless CMS migration powering the first US heavy-machinery e-commerce.
- Owning the full stack: Next.js App Router on the web, React Native for the field-rep app, and the TypeScript backend that ties them together.
- Setting the engineering bar — code review, accessibility (WCAG 2.1 AA), performance budgets, and the hiring loop for new engineers.
Luizalabs (Magazine Luiza)
Senior Software Engineer ·
- Shipped React Native features inside the Magazine Luiza Superapp — one of Brazil's most-installed retail apps, serving tens of millions of monthly users.
- Worked on payment, checkout, and personalization surfaces; raised test coverage and shipped behind feature flags so launches were boring.
- Collaborated across iOS, Android, web, and native teams to keep parity across platforms at retail scale.
Corebiz (VTEX)
Software Engineer ·
- Delivered VTEX e-commerce storefronts and integrations for retail clients across Latin America.
- Built React + TypeScript surfaces backed by VTEX IO, focused on conversion-critical pages (PDP, checkout, cart).
- Bridged design hand-off, accessibility, and SEO requirements with the realities of an e-commerce platform on tight retail deadlines.
UAUBox
Full Stack Developer ·
- Pivoted from IT support into engineering — first paid role writing production code.
- Shipped customer-facing features across the React frontend and the Node.js backend of a subscription-box e-commerce.
- Learned the full software-delivery loop on the job: code review, deploy, on-call, customer feedback.
Klabin S/A
IT Support Analyst ·
- Seven years on the IT helpdesk for one of Brazil's largest pulp & paper manufacturers — production lines, factory floor, corporate users.
- Diagnosed everything from broken PLCs to ERP timeouts; learned how real businesses actually use software (and why they hate it).
- Started teaching myself JavaScript on nights and weekends; that habit is what made the UAUBox pivot in 2019 possible.

What I'm doing now
Wrapped up my time at Machinery Partner in April 2026 after leading the no-code → Next.js migration that became the first US heavy-machinery e-commerce. Currently open to work — looking for principal or senior full-stack roles in web, mobile, or product-focused teams. Writing the occasional engineering post on /blog in the meantime.
