Technical Insights & Architecture Papers
Deep-dives on high-throughput backend architecture, Python & Django performance, real-time Voice AI, and resilient database modeling.
Enterprise OAuth2 & OIDC PKCE Authentication: Stateless JWTs vs. Revocable Redis Session Stores
Storing JWTs in localStorage opens critical XSS vulnerabilities, while traditional database sessions fail under horizontal API scaling. Master the hybrid architecture: short-lived access tokens, HttpOnly rotating refresh tokens, and instant Redis blocklists.
Hardening Web Security: Dynamic CSP Nonces, Subresource Integrity & Trusted Types in Django
Most websites neutralize their Content Security Policy (CSP) with 'unsafe-inline' to accommodate analytics and widgets. Master how to inject cryptographically secure per-request CSP nonces, enforce Subresource Integrity (SRI), and implement Trusted Types without breaking third-party scripts.
Zero-Public SSH: Hardening Cloud VPS Access with WireGuard Mesh Networks & UFW
Exposing SSH port 22 invites thousands of automated brute-force attacks daily. Discover how to bind sshd exclusively to an internal WireGuard mesh network and lock down public firewall rules with UFW.
Multi-Tenant SaaS Architecture: Row-Level Security (RLS) vs. Separate Schemas
Choosing between shared-database row filtering and schema-per-tenant has massive consequences for database connection pooling, migrations, and operational maintenance. Here is an architectural deep-dive into PostgreSQL RLS.
High-Throughput Financial Statement OCR & Tabular Data Extraction
Parsing scanned multi-page bank statements and financial PDFs with irregular grid layouts, merged cells, and varied DPI breaks standard OCR models. Discover how to build a resilient, memory-bounded financial extraction pipeline.
Implementing Passkeys & WebAuthn in Modern Web Applications
Passkeys replace phishing-prone passwords with cryptographic public-key pairs bound to biometric hardware. Here is a practical engineering guide to implementing WebAuthn registration and authentication in web applications.
