About me

I’m a Senior Full-Stack Software Engineer with 13+ years of experience building and modernizing SaaS and business-critical systems. I enjoy solving complex problems and combine backend architecture depth with hands-on React, Node.js, and Laravel/PHP expertise to deliver reliable software end-to-end.

Senior Full-Stack Software Engineer with 13+ years of experience building, modernizing, and scaling business-critical web applications and SaaS platforms.

I specialize in full-stack product development, backend engineering, SaaS architecture, APIs, legacy modernization, and cloud-based systems, with strong hands-on experience across React, Next.js, Node.js, Laravel/PHP, PostgreSQL, MySQL, Redis, AWS, and GCP.

Throughout my career, I have worked on multi-tenant SaaS platforms, real-time collaboration systems, workflow automation, data-intensive applications, payment integrations, and business-critical legacy systems.
I am particularly effective on projects where a client needs more than implementation capacity, someone who can understand an existing system or business process, make technical decisions, improve reliability and performance, and take ownership from architecture and development through testing, deployment, and production.

Selected results include:
• Built and scaled features for a SaaS workforce analytics platform used by leading organizations and government agencies in Australia.
• Delivered an AWS pricing comparison MVP from scratch in approximately 72 hours, integrating AWS APIs, Lambda, and DynamoDB.
• Automated extraction and consolidation of data from 1,000–3,000 government PDF files, reducing processing time from weeks to hours.
• Built real-time applications using WebSockets and production-ready backend architectures.
• Modernized legacy PHP applications, optimized databases and queries, introduced Docker-based development environments, and implemented CI/CD pipelines.
I have 4+ years of remote experience working across Brazil and Australia, collaborating with distributed engineering, product, design, and business teams.
Core expertise
Frontend: React, Next.js, JavaScript, TypeScript
Backend: Node.js, Laravel, PHP, REST APIs, GraphQL
Data: PostgreSQL, MySQL, MongoDB, DynamoDB, Redis
Cloud & DevOps: AWS, GCP, Docker, Jenkins, CI/CD, Serverless

I am available for remote contract and project-based opportunities, particularly where strong engineering ownership, technical problem-solving, and long-term maintainability are important.
