About

Hi, I'm Werlesson

I turn business problems into software that ships and scales. I lead architecture decisions end to end — from Vue and Nuxt interfaces to Laravel APIs, data modeling and Docker-based deploys — and I optimize for outcomes, not output. I take SaaS products from first commit to production, owning quality, performance and delivery as one responsibility.

Where I focus

SaaS Development

Design and ship multi-tenant SaaS products, from billing and auth to scale.

Frontend Architecture

Structure Vue and Nuxt applications that stay fast and maintainable as they grow.

Laravel APIs

Build resilient, well-modeled backends with clear domain boundaries.

System Design

Model data, services and infrastructure for reliability and growth.

How I engineer

  • Architecture First Decisions are cheaper before the code exists.
  • Performance Matters Speed is a feature users feel on every page.
  • Developer Experience Good DX compounds into faster, safer delivery.
  • SEO by Default Discoverability is built in, not bolted on.
  • Scalable Systems Design for the load you'll have, not just the one you have.
  • Clean Code Readable code is the cheapest code to change.

Roles where I turned engineering into business impact.

Senior Software Engineer

Grupo DNR

May 2022 – Present

Responsibilities
  • Make architecture decisions and contribute to the technical evolution of B2B SaaS products and internal systems
  • Design and ship an offline-first mobile inspection app (React Native/Expo, SQLite) with its own design system — from first commit to production release
  • Build Vue interfaces, reusable components and REST API integration
  • Implement Laravel backend endpoints — auth, validation, access policies and API resources
  • Model and optimize MySQL queries over a large-scale data model; ship async workloads with Laravel Queue
  • Integrate external services — insurance carriers, enterprise ERP, enterprise SSO
Business impact

~4 years working across the group's automotive product ecosystem, on web and mobile products — front to back, with hundreds of deliveries over the period. Built the mobile inspection app from scratch: main author of the code and of every product and architecture decision, reusing the existing backend. That brought inspections — previously possible only on the web — to mobile, giving field inspectors more speed.
