I’m a Senior Software Engineer with Staff-level scope, focused on backend systems, cloud infrastructure, and production reliability on AWS.

I design distributed systems, define infrastructure and deployment patterns, and stay deeply hands-on building backend services using Python (FastAPI) and Node.js. My work spans architecture decisions, infrastructure as code with Terraform, CI/CD automation, and operating systems in production.

I care about how systems behave after they ship. Reliability, observability, security, and cost efficiency are first-class concerns in everything I build.

Currently focused on backend, cloud, and platform-oriented roles.

• Design backend and service architectures for scalable systems
• Build and operate cloud infrastructure on AWS using Terraform
• Develop backend services and APIs in Python (FastAPI) and Node.js
• Design event-driven and serverless systems (SQS, SNS, Lambda)
• Own CI/CD pipelines, deployment safety, and environment isolation
• Improve production reliability through observability and automation
• Mentor engineers and review designs to keep systems coherent

Front-end work (React) is something I step into when needed, but backend, cloud, and infrastructure are my primary focus areas.

• Design for failure and recovery, not the happy path
• Treat infrastructure and deployments as first-class code
• Make system behaviour observable before optimizing it
• Prefer simple, explicit architectures over clever abstractions
• Optimize for long-term ownership, not short-term delivery
