Black Assassins E-Sport
Founder & Sysadmin Side Project
Mar 2014 — Jun 2020 Started because local servers kept dying to DDoS attacks, figured I could do better with a $5/month DigitalOcean box Grew into top 10 ranked server worldwide, 85,000+ players over 6 years Built Django tool to auto-provision servers (was basically an RCE waiting to happen, but I didn't know better) Found SQL injection in B3 server tool, got paid in Riot Points because I didn't have a bank account Learned DDoS mitigation the hard way - Cloudflare, fail2ban, and a lot of reading sketchy forum posts Dug into IW engine code to make servers run smoother than the competition This is where I got hooked on infrastructure, Linux, and keeping things running when people try to break them Ran it for 6 years while going through school and university → view project Linux Networking Server Administration Django DDoS Mitigation

RAG architectures, vector databases, and GPU orchestration. Created Tera, a local-first AI
assistant built with Rust. Passionate about privacy-preserving AI that runs on-device.
Technical Range
Work spans: AI Infrastructure (local LLMs, ML pipelines, RAG, PyTorch), Platform Engineering
(Kubernetes, observability, service mesh, GPU orchestration), and Systems (eBPF, Rust, Go,
Linux internals).
Founder Mindset
Founded and ran a gaming community for 6 years, building infrastructure that served
thousands of users. Built observability tools now used by developers daily. Approaches
problems end-to-end, from design to production to on-call. Prefers building solutions over
talking about them.
Current Work
Senior Software Engineer at WSO2, building Choreo developer platform. Architected
eBPF-powered observability processing 500GB/day. Led Cilium CNI migration on 10,000+ pod
cluster. Speaker at Conf42, KCD, and cloud-native events.
