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.
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.
PostgreSQL Query Planner Internals: Calibrating Cost Factors, Work Memory, and SSD Random Page Penalties
Default PostgreSQL configuration parameters were calibrated decades ago for spinning magnetic hard disks. Learn how the cost-based optimizer calculates query plans and how to tune random_page_cost and work_mem for modern NVMe SSD storage.
PostgreSQL Declarative Partitioning at 50M Rows/Day: Automating Partition Pruning, Maintenance & Retention with pg_partman
Monolithic tables ingest millions of daily records until index bloat and autovacuum lockups cripple query performance. Master PostgreSQL native range partitioning and automated lifecycle maintenance with pg_partman.
