About
A pragmatic engineer, obsessed with craft.
I bridge product, systems, and security. From TypeScript microservices to hardened Linux edges, I build things that stay up, ship fast, and don't leak.
Product-minded
Every line of code serves a user outcome. Ship value early, iterate ruthlessly.
Systems thinker
Distributed backends, event-driven pipelines, observability by default.
Security-first
Zero-trust networks, hardened Linux, encrypted everything. Threat model first.
Selected work
Products built for scale.
A curated selection of enterprise systems, security infrastructure, and developer platforms shipped over the last several years.

Network security
Ship fast. Sleep safe.
A dedicated practice built on top of full-stack fluency. Every service I ship is threat-modeled, monitored, and hardened by default.
Zero-Trust Networks
mTLS, SPIFFE identity, per-request authorization at the edge.
Hardened Linux
SELinux, seccomp, kernel-level auditing on every host.
Cloud Security
Least-privilege IAM, encryption at rest, immutable audit trails.
Edge & CDN
WAF, bot mitigation, geo-fencing, and DDoS-resilient origins.
Infrastructure
Terraform, GitOps, blue/green, canary releases with automatic rollback.
Data Protection
Envelope encryption, tokenization, and privacy-by-design pipelines.

From front-end to full-stack.
