Senior Full-Stack
Software Engineer.
I'm André Ferreira — a senior full-stack engineer with 10 years helping startups and larger teams ship products that scale. I favor clear service boundaries, honest trade-offs, and systems that stay legible as they grow.
Most of my work spans distributed systems, software architecture, and blockchain: AWS and serverless, data-heavy paths, and smart-contract integration where it belongs in the product.
