Mid-Level .NET Software Engineer — APIs, Integrations & Greenfield Delivery

Building reliable .NET and Azure systems, secure integrations, and API governance layers.

I work across the technical lifecycle: from designing robust backends and API control layers (APIM) to shipping high-performance systems. I focus on reliability, zero-trust security, and measurable business impact.

About

Pedro Bertoluchi

Building secure .NET systems and enforcing robust API governance.

I'm Pedro, a software engineer with deep expertise in the .NET and Azure ecosystems. I specialize in designing distributed architectures, enforcing API governance (Azure API Management), and delivering secure full-stack platforms. My pragmatism drives my code: I prioritize observability, frictionless integrations, and building systems that remain resilient under heavy operational stress.

What I deliver

  • Strong technical execution for greenfield initiatives: from whiteboard architecture to production rollout.
  • Azure APIM Gateway implementation: enforcing centralized traffic control, abuse protection, and standardized telemetry.
  • Enterprise integration optimization: reducing architectural friction and boosting reliability via messaging and Redis.
  • AI/RAG automation flows that reduced operational document retrieval time and improved decision-making.
  • Engineering standardization through reusable API/SignalR templates, significantly accelerating the team's time-to-market.

Why Work With Me

What I bring to every project

End-to-End Execution

I contribute across the full technical lifecycle, from initial architecture discussions to deployment and production observability.

Security & Governance

I treat APIs as critical infrastructure, enforcing strict governance, zero-trust security, and rate limiting via Azure APIM.

Operational Efficiency

My main focus is reducing architectural friction and improving system reliability under heavy operational loads.

Engineering Standards

I prioritize measurable business value, standardizing codebases to accelerate the team's delivery cycles.

Business-First Focus

Systems built to solve real bottlenecks: operations, workflow automation, inventory tracking, and critical path performance.
