About
Professional Summary
I lead Level-3 technical support for enterprise cloud and AI platforms, where the hardest escalations land. My background spans Google Cloud architecture, high-stakes financial services environments at Barclays Capital, and the operations behind modern AI services like Gemini, ChatGPT, and Claude.
I'm the person teams call when an incident is ambiguous, time-sensitive, and visible to stakeholders. I pair deep GCP and identity/security expertise with calm, precise communication — turning chaotic outages into clear root-cause stories and lasting fixes.

Personal Projects
Things I build for fun
Self-hosted, from-scratch engineering — security tooling, platform internals, and full-stack products.
Sova — Live Emotional-Support Video Chat
sovatalk.comA production platform for anonymous, on-demand live video chat and private 1-on-1 sessions with empathetic listeners, with cryptocurrency (Bitcoin / Lightning) payments. Beyond the product, it is a complete cloud-native DevOps implementation — full CI/CD · GitOps · DevOps across multi-node Dev / UAT / Production environments. A Dockerised Next.js application plus background workers run on Kubernetes (k3s) across three separate environments; Argo CD continuously reconciles each from Git (app-of-apps, Sealed Secrets, CloudNativePG); GitHub Actions drives automated SemVer releases, container image builds to GHCR, vulnerability scanning, automatic UAT deployment, and gated promotion to Production; Terraform and Ansible provision and configure the infrastructure. Real-time media runs on LiveKit (WebRTC) behind host nginx + Let's Encrypt, with BTCPay Server for payments. Full-stack observability closes the loop — a self-hosted Sentry instance captures real-time error and performance monitoring across every environment.
SAML + OIDC SSO Identity Provider
sso.fsmaster.comA complete SAML 2.0 + OpenID Connect Identity Provider written in pure Python — with no SAML/OIDC libraries. Hand-rolled XML signing, assertions, and token flows to drive single sign-on for Google Workspace.
track — URL & Screenshot IP Logger
scerenshot.appGrabify-style short links that capture each visitor's IP, geolocation (country / region / city on a live map), and device details. Supports URL redirects and image serving, with a built-in analytics dashboard.
neonmail — Free, Privacy-First Email
neonmail.ioA free, privacy-first webmail service — fast, clean, and self-hosted, with no ads and no tracking. Built on Next.js with a lightweight SQLite backend and shipped through a GitHub Actions CI/CD pipeline behind nginx + Let's Encrypt.
HAR Fixer — Repair HARs for Google HAR Analyzer
harfixer.com
A support-engineering tool that fixes the customer HAR files Google HAR Analyzer rejects:
sanitized bodies still flagged as base64, malformed JSON, truncated exports and missing fields. Built by
reverse-engineering the analyzer's loader, which the tool replays to show which request crashes it and why.
Runs 100% client-side (CSP connect-src 'none'), with an optional redaction pass and a zero-dependency CLI.
LeakCheck — What Your Browser Tells Every Website
fsmaster.com/leakcheckA browser-fingerprint and leak inspector that shows ~200 signals anti-fraud tools like SEON, Castle and FingerprintJS use to recognize a device: IP and WebRTC leaks, TLS cipher list, Client Hints, unmasked GPU, canvas and audio hashes, fonts, time zone and more. It flags the inconsistencies risk engines score, and compares two browsers to show whether they can be linked. No storage, no cookies; the server only echoes the request back.
