Designing an Agent Identity and Access System: Credential Scoping, Token Lifecycle, and Least-Privilege Enforcement for Production AI Agents
Per-agent scoped credentials, just-in-time token issuance, credential broker architecture, and OWASP Agentic Top 10 mitigations for production AI agent systems. With TypeScript implementations.
AI-Assisted Development Workflows in Production: Integrating Coding Agents, Automated Review, and Human Oversight Into Your SDLC
How engineering teams are restructuring their SDLC around AI coding agents: workflow patterns, CI/CD pipeline changes, effectiveness metrics, team structure shifts, and production guardrails that actually work.
Designing a Unique ID Generator: UUIDs, ULIDs, Snowflake IDs, and Database Sequences for Distributed Systems
A practical guide to the four main approaches for generating unique identifiers in distributed systems: auto-incrementing sequences, UUIDs (v4 and v7), ULIDs, and Snowflake-style IDs. Covers TypeScript implementations, sortability, collision probability, index fragmentation, clock skew, and migration strategies.
Designing APIs for AI Agent Consumption: Structured Actions, Self-Describing Responses, and Tool-Friendly Patterns in TypeScript
AI agents are now first-class API consumers. This guide covers the patterns that make APIs consumable by LLM-powered agents: structured action endpoints, self-describing responses, deterministic pagination, error messages that enable self-correction, and production considerations for rate limiting, auth, and observability when agents are your primary API consumer.
Database Concurrency Control in Practice: Isolation Levels, Locking Strategies, and MVCC for Production Systems
A practical guide to database concurrency control covering the four SQL isolation levels with real anomaly examples, how MVCC works in Postgres and MySQL, optimistic vs pessimistic locking patterns with TypeScript code, and concrete guidance for double-spending prevention, inventory reservation, and financial ledgers.
Designing a Code Execution Sandbox: Container Isolation, Resource Limits, and Secure Multi-Tenant Code Running at Scale
A system design deep dive into building a secure code execution sandbox for online judges, AI agent tool execution, and developer playgrounds. Covers container isolation levels, language-level sandboxing, resource limiting with cgroups, execution lifecycle, multi-tenant scheduling, and output streaming.
Designing a News Feed System: Fan-Out Strategies, Ranking Algorithms, and Real-Time Updates at Scale
A deep dive into news feed system design covering push vs pull fan-out models, hybrid celebrity handling, feed ranking, real-time delivery with SSE and WebSockets, Redis sorted set timelines, and cache invalidation patterns for materialized feeds.
LLM Cost Engineering in Production: Token Budgets, Model Routing, and Unit Economics for AI-Powered Applications
A production guide to LLM cost engineering covering token budget enforcement with per-request circuit breakers, intelligent model routing, semantic caching, agent loop containment, Cost per Successful Task as a unit economics KPI, and organizational governance for shadow AI spend.
Designing a Bidirectional Data Sync Engine: Conflict Resolution, Change Detection, and Multi-System Consistency at Scale
How to build the infrastructure that keeps data consistent across your application and multiple external systems. Covers change detection, conflict resolution with vector clocks, tombstone handling, idempotent sync operations, and error recovery in multi-system updates.
Reliability Engineering for Multi-Agent Pipelines: Compound Failure Math, Redundancy Patterns, and SLO Budgets at Scale
When 10 agents each run at 95% reliability, the pipeline delivers 60%. When each step in a 10-step task has 85% success, the pipeline succeeds 19.7% of the time. This article covers compound failure math, redundancy patterns, SLO budget allocation, and monitoring strategies for multi-agent systems in production.
Designing a Distributed Key-Value Store: Storage Engines, Replication, and Tunable Consistency
A ground-up walkthrough of distributed key-value store design: LSM trees vs B-trees, consistent hashing, Raft vs leaderless replication, quorum reads/writes, hinted handoff, anti-entropy, and hot key handling. Includes TypeScript abstractions and a consistency/availability/latency tradeoffs table.
Designing a Video Processing Pipeline: Upload, Transcoding, Adaptive Bitrate Streaming, and CDN Delivery at Scale
A deep dive into architecting a production video processing pipeline: resumable chunked uploads, transcoding job orchestration across quality presets, HLS and DASH segment generation, CDN cache warming, and the tradeoffs between latency-optimized and cost-optimized pipeline designs. Covers DRM, thumbnail generation, content fingerprinting, and multi-tenant isolation.
