Technical Insights & Architecture Papers
Deep-dives on high-throughput backend architecture, Python & Django performance, real-time Voice AI, and resilient database modeling.
Redis Memory Fragmentation & jemalloc Tuning: Diagnosing OOM Kills and Calibrating Active Defragmentation in Production
Redis nodes frequently get killed by the Linux OOM-killer even when used_memory is well below host limits. Learn how to diagnose jemalloc allocator fragmentation and configure active defragmentation safely.
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.
KV Cache Eviction & Prompt Prefix Caching in vLLM: Reducing TTFT by 80% Across Multi-Turn Voice AI Dialogues
Multi-turn telephony voice agents suffer massive TTFT latency stalls as context grows. Learn how to configure RadixAttention and prefix caching in vLLM to achieve sub-100ms first-token generation in production.
Deterministic Structured Outputs from LLMs: Enforcing Pydantic Schemas via Grammar-Constrained Decoding & Outlines
Prompting LLMs to respond in valid JSON inevitably fails under edge cases, triggering expensive retry loops. Learn how grammar-constrained decoding masks invalid token logits at the sampling level to guarantee 100% deterministic Pydantic schema compliance.
WebRTC Selective Forwarding Unit (SFU) Architecture: Packet Loss Concealment, Jitter Buffers, and Simulcast in Voice AI
Lossy mobile networks, bursty UDP drops, and jitter destroy real-time voice AI conversations. Explore how Selective Forwarding Units (SFUs) leverage Opus in-band forward error correction and adaptive jitter buffers to maintain sub-150ms audio streams.
Defending Against N+1 Queries in GraphQL & REST: Implementing the DataLoader Pattern and Batch Querying in Django
Nested REST serializers and GraphQL resolvers frequently trigger cascading N+1 query storms that collapse database performance under concurrency. Implement the asynchronous DataLoader pattern in Django to batch and coalesce foreign key lookups.
