Technical Insights & Architecture Papers
Deep-dives on high-throughput backend architecture, Python & Django performance, real-time Voice AI, and resilient database modeling.
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.
Server-Sent Events (SSE) vs. WebSockets for LLM Streaming & Real-Time Dashboards
Developers routinely spin up bidirectional WebSockets for AI chat interfaces and live feeds, incurring stateful proxy overhead when unidirectional Server-Sent Events are lighter, auto-reconnecting, and HTTP/2 multiplexed.
High-Performance Full-Text Search: PostgreSQL `tsvector` vs. Elasticsearch
Engineering teams often deploy and maintain complex, RAM-heavy Elasticsearch or Meilisearch clusters when native PostgreSQL already handles 95% of search use cases at a fraction of the cost. Here is how to configure tsvector, pg_trgm, and GIN indexing.
Telephony Bridge Architecture: Connecting Twilio SIP Trunks to LiveKit WebRTC
Bridging legacy telephone networks (PSTN via SIP) into ultra-low latency WebRTC voice pipelines often introduces audio transcoding delays and dropped frames. Discover how to architect a direct Twilio SIP to LiveKit SFU media bridge.
Achieving Perfect Core Web Vitals on a Custom VPS: Zero Edge CDN Bloat
You do not need expensive edge serverless platforms or heavy JavaScript frameworks to achieve 99+ Core Web Vitals scores. Here is how to configure Nginx, optimize assets, and eliminate layout shifts on a single VPS.
