About Me

With over 5 years of experience in backend development and infrastructure engineering, I specialize in building robust systems that can scale in response to evolving customer needs. I have experience working in high velocity teams across a variety of tech stacks.

System Architecture

Designed and implemented scalable services and distributed systems

Cloud Infrastructure

Integrated with cloud providers like AWS with a focus on automation and reliability

Data Engineering

Optimized database performance and built robust data pipelines

Security & DevOps

Implemented security best practices and CI/CD automation

My Philosophy

I believe that great design becomes second nature to users and that great systems evolve well to changing technologies and customer needs. My approach combines technical excellence with pragmatic decision-making, always balancing long-term change with short-term business needs. My two guiding principles are excellence and service: excellence in my work and in my results, and being of service to my coworkers and customers. I am also a strong proponent of growth mindset.
