Cloud Infrastructure & Full-Stack Engineer | San Francisco

About Me

Hello! I am an independent software engineer based in Silicon Valley (Santa Clara, CA). I specialize in cloud-native architecture, distributed systems, and scalable web applications. Working primarily with early-stage startups in the Bay Area, I help turn complex product requirements into fast, reliable, and secure digital infrastructure.

I manage my own hardware and staging environments to ensure total control over performance and data security for my clients.

Current Focus Areas

Cloud Infrastructure

Designing highly available server architectures on AWS and GCP, focusing on low-latency delivery, zero-downtime deployments, and container orchestration.

Edge Computing

Leveraging distributed networks to push application logic closer to the user, improving global response times for data-intensive SaaS products.

API Development

Building and maintaining secure REST and GraphQL APIs that serve mobile and web clients, handling thousands of concurrent requests smoothly.

Serverless Computing

Architecting event-driven, serverless applications using AWS Lambda and Google Cloud Functions to reduce operational overhead and scale automatically.

Get In Touch

I am currently taking on new contract roles for Q2 and Q3 of 2026. If you have an infrastructure or full-stack project you'd like to discuss, please drop me a line.
