About Me

Cloud and Network Engineer with 10+ years of experience in cloud engineering, networking, Python development, and AI technologies.

I bring expertise across Azure, AWS, GCP, Kubernetes, Docker, Terraform, and enterprise networking protocols including BGP, OSPF, and SD-WAN. Currently at Microsoft as an Azure Tech Support Engineer SE, I specialize in complex hybrid cloud networking solutions for Fortune 500 clients.

My career has taken me from Cisco TAC to global-scale network engineering at Schlumberger, nationwide infrastructure projects at Telefonica, and now cutting-edge cloud + AI work at Microsoft. I'm a 3x Microsoft Global Hackathon participant and passionate about leveraging AI to transform operations.

Why Work With Me

What I bring to your team from day one

01

Battle-Tested at Scale

I've designed networks spanning 300+ sites across continents, managed $200M+ infrastructure projects, and supported Fortune 500 clients in banking and healthcare. I don't just know the theory - I've done it at enterprise scale.

02

I Build What Doesn't Exist

When case resolution was too slow, I built a custom AI agent with MCP servers that cut response time by 200%. When 300+ sites needed connectivity, I designed a BGP architecture that saved $1M+/year. I find problems and engineer solutions.

03

Cloud + Network = Rare Combo

Most engineers know cloud or networking. I bring deep expertise in both - from BGP/OSPF routing policies to Kubernetes clusters to AI automation. This dual fluency is what makes me effective in hybrid environments.

04

Proven Innovation Track Record

3× Microsoft Global Hackathon participant. I'm not just maintaining systems - I'm actively pushing boundaries with AI, automation, and new tools. I bring that innovation mindset to every team I join.

Let's Talk

Whether it's a cloud architecture challenge, a networking puzzle, or an AI opportunity - I'd love to hear about it.

I'm currently open to Senior Cloud Engineer, Network Architect, and Platform Engineer roles - remote or hybrid in Seattle, WA.
