I'm a Lead Full-Stack Engineer at Cinnova with 7+ years shipping production systems — from high-traffic consumer platforms to IRS electronic filing infrastructure. I combine React/TypeScript and Python/Django depth with a specialty in secure Azure architecture, encrypted data exchange, and compliance-sensitive workloads (PII, HIPAA, tax filing).

Selected impact:

• Migrated 700M+ database rows with zero downtime at Insurify
• Shipped 250+ A/B test features contributing to up to ~10× business growth
• Improved session creation speed up to 40× via async pipeline redesign
• Built real-time chat and notifications using Server-Sent Events in Remix.js
• Co-founded Taskbarter, an open-source skill-sharing platform (20,000+ lines contributed)

• IRS A2A e-filing pipelines (1099, 5498, 1042) with Azure-native security controls
• Secure SFTP/PGP data exchange — RSA-4096 key management and GPG trust chains
• MCP-based AI tooling in DevSecOps workflows for AI-assisted security review
