Senior Backend Developer and Software Architect

I design backend systems built for scale, resilience, and critical operations.

I am Danilo Pinotti, a Senior Backend Developer and Software Architect with more than 10 years of experience building web applications, distributed systems, and critical software for finance, retail, education, and IoT.

My work is centered on backend engineering, architecture evolution, automated testing, observability, payment integrations, and long-term maintainability. I have spent most of my career modernizing production systems, improving reliability, and helping teams ship with more confidence.

What I focus on

Architecture and modernization

I work on evolving existing systems without losing control of production risk, especially in legacy or high-impact environments.

Critical backend systems

I design and implement services for high transaction volume, secure integrations, idempotent operations, and operational resilience.

Quality and reliability

Automated tests, observability, and production feedback loops are central to how I improve confidence and maintainability.

Technical leadership

I have led teams, supported junior developers, defined standards, and helped connect engineering decisions to business constraints.
