Technical Insights & Architecture Papers
Deep-dives on high-throughput backend architecture, Python & Django performance, real-time Voice AI, and resilient database modeling.
PostgreSQL Point-in-Time Recovery (PITR) & Continuous WAL Archiving with pgBackRest and S3/MinIO: Zero-RPO Disaster Recovery Architecture
Eliminate database data loss windows with continuous Write-Ahead Log (WAL) streaming and deterministic Point-in-Time Recovery (PITR) using pgBackRest and S3-compatible object storage.
PostgreSQL Index-Only Scans & Covering Indexes: Eliminating Heap Fetches on High-Throughput Read APIs
Eliminate disk I/O bottlenecks in PostgreSQL read APIs by architecting Covering Indexes with the INCLUDE clause and tuning Visibility Maps to guarantee true Index-Only Scans.
Horizontal Database Sharding at Scale: Citus Distributed Tables, Distributed Transactions, and Partition-Wise Joins
When a single PostgreSQL primary reaches write saturation and storage limits, Citus transforms PostgreSQL into a distributed cluster. Master shard keys, 2PC distributed transactions, and co-located joins.
SQLite in High-Concurrency Server Production: WAL2 Mode, Memory-Mapped I/O (mmap), and 15,000+ Reads/Sec on the Edge
Dismissed as an embedded toy, modern SQLite can power blazing-fast edge backends and microservices. Discover WAL2 checkpoints, mmap_size, PRAGMA connection pooling, and multi-reader concurrency patterns.
PostgreSQL TOAST Internals & Large JSONB Bloat: Eliminating Compression Overhead and Out-of-Line Storage Traps
High-volume JSONB and text columns trigger PostgreSQL TOAST tables, silently degrading read throughput and inflating disk I/O. Master storage strategies, LZ4 vs pglz compression, and out-of-line detoasting tuning.
Redis Streams Consumer Group Reliability: Recovering Stalled Messages with Pending Entries Lists (PEL) and XAUTOCLAIM
When distributed workers crash mid-execution, messages remain trapped in Redis Streams Pending Entries Lists (PEL). Master consumer group recovery, poisoned message routing, and automated re-claiming with XAUTOCLAIM in Python.
