Designing a Data Retention and Archival System: TTL Policies, Cold Storage Tiers, and Compliance-Driven Data Lifecycle Management
Every production database grows until compliance or cost forces a rethink. This guide covers TTL policies, hot/warm/cold storage tiers with transparent query routing, GDPR/HIPAA/SOC2 retention rules, archival pipelines, and deletion that actually works.
Designing a Stock Exchange: Order Matching Engines, Order Books, and Low-Latency Trade Execution at Scale
A deep dive into stock exchange system design covering order book data structures, price-time and pro-rata matching algorithms, kernel bypass for sub-microsecond latency, multicast market data distribution, and the production challenges of deterministic replay, fault tolerance, and regulatory audit trails.
Designing a Webhook Ingestion Pipeline: Signature Verification, Idempotent Processing, and Event Routing for Multi-Provider SaaS
A practical guide to building a production webhook ingestion pipeline that handles signature verification across providers, deduplicates events, routes to internal consumers, and surfaces observability signals when a provider goes silent.
Contract-First API Development with OpenAPI: Schema-Driven Validation, Type Generation, and Client SDK Automation in TypeScript
Contract-first API development means writing the OpenAPI spec before writing a single route handler. This guide covers the full workflow: type generation with openapi-typescript, request/response validation in Hono and Next.js, mock servers for frontend teams, client SDK generation, contract testing in CI, and strategies for evolving contracts without breaking consumers.
Designing a Rate Limiter: Token Buckets, Sliding Windows, and Distributed Rate Limiting at Scale
A deep dive into rate limiting algorithms, distributed coordination with Redis, per-user and per-API-key enforcement, and the production problems most implementations ignore: race conditions, clock drift, graceful degradation, and placement in the request path.
Building Resilient API Clients in TypeScript: Rate Limit Handling, Adaptive Throttling, and Retry Coordination for Third-Party Integrations
Every SaaS app integrates with third-party APIs that enforce rate limits differently. This guide covers token buckets, adaptive throttling, Redis-coordinated distributed limits, circuit breaking, and monitoring — with a reusable TypeScript HTTP client wrapper.
Designing API Authentication for B2B SaaS: API Keys, OAuth Client Credentials, and Scoped Access Tokens
A production guide to B2B API authentication covering API key generation and hashing, OAuth 2.0 client credentials flow, scoped access tokens, rate limiting per key, audit logging, webhook signature verification, key rotation, and key compromise response in TypeScript.
Building AI Features on a Startup Budget: Model Selection, Managed vs Self-Hosted, and Production AI Without a Dedicated ML Team
Most seed-stage startups cannot afford a $240K AI engineer. This guide covers how to choose between managed APIs, open-source models, and fine-tuned alternatives, with real cost breakdowns, provider-portable codebase patterns, and when to bring in fractional AI expertise instead of hiring full-time.
Multi-Provider LLM Reliability: Failover Strategies, Provider Abstraction, and Inference SLAs for Production AI
Single-provider LLM setups are fragile by design. This article covers building a provider abstraction layer with circuit breakers, latency-based routing, cost-aware model selection, token budget enforcement, and inference SLA monitoring across OpenAI, Anthropic, and open-source models.
Nix for Development Environments: Flakes, Dev Shells, and Reproducible Builds That Eliminate Configuration Drift
Docker dev containers and asdf get you close to reproducibility, but not all the way. Nix flakes close the remaining gap: exact package versions, hermetic builds, and per-project toolchains that activate automatically. This guide covers flake.nix structure, devShells, direnv integration, CI parity, overlays, and the real downsides before you commit.
Traffic Shaping in Production: Rate Limiting, Request Hedging, and Adaptive Concurrency for Resilient Services
A production guide to traffic shaping techniques: token bucket and sliding window rate limiting with TypeScript implementations, request hedging to cut tail latency, adaptive concurrency limits that self-tune under load, priority traffic classes, and load shedding at the ingress layer.
Running Hackathons That Ship: Planning Innovation Weeks, Evaluating Projects, and Turning Prototypes into Product Features
A practical guide to structuring engineering hackathons that produce shippable outcomes: theme selection, team formation, production-readiness judging, post-event integration pipelines, and measuring ROI over time.
