Spec-Driven Development for AI Engineering Teams: Writing Specifications That AI Agents Can Execute
Vague prompts produce vague code. This guide covers how to structure specifications for AI coding agents: acceptance criteria, interface contracts, constraints, test cases, and a complete spec-to-code workflow with real TypeScript examples showing good vs bad specs and their actual output quality.
Automated Capacity Planning for Startups: Load Profiling, Bottleneck Detection, and Predictive Scaling
A practical guide to capacity planning for startup engineering teams without a dedicated platform team. Covers load profiling, bottleneck detection, automated right-sizing, predictive scaling, and lightweight dashboards using Prometheus, Grafana, Kubernetes HPA, and Cloudflare Workers analytics.
Database Performance Testing in CI/CD: Query Benchmarks, Migration Impact Analysis, and Regression Detection
How to catch database performance regressions before they reach production, covering query baselines, migration impact analysis, pgbench integration, performance gates, and connection pool stress testing in GitHub Actions.
Securing Your CI/CD Pipeline: OIDC Authentication, Artifact Signing, and Runtime Attestation for Production Deployments
Long-lived credentials in CI are an accident waiting to happen. This guide covers replacing static secrets with OIDC federation, signing build artifacts with Sigstore/cosign, generating SLSA provenance, and enforcing signed images at runtime with Kubernetes admission controllers.
Negotiating Technical Scope with Non-Technical Stakeholders: Trade-off Frameworks, Visual Communication, and Getting Buy-In for Engineering Investment
A practical guide for CTOs and tech leads on translating technical tradeoffs into business language, using visual frameworks for scope decisions, and running negotiations that protect engineering investment without losing stakeholder trust.
Running an Engineering Reorganization: Team Splits, Reporting Changes, and Maintaining Velocity Through Structural Transitions
Reorgs at the 15-50 engineer scale break more often than they help. Here is a practical framework for reading the right signals, designing team boundaries that last, executing the transition without losing momentum, and measuring whether the change actually worked.
When to Build vs Buy: A Decision Framework for Startup CTOs
A structured framework for startup CTOs navigating the build-vs-buy dilemma. Covers hidden costs on both sides, a weighted evaluation matrix, category-level defaults, real decision examples, and how AI coding tools are reshaping the calculus in 2026.
Designing a Distributed Cache: Eviction Policies, Cache Coherence, and Multi-Tier Caching at Scale
A system design deep dive on building a distributed caching layer. Covers LRU, LFU, and TTL eviction algorithms, cache coherence in multi-node setups, write-through vs write-behind patterns, multi-tier caching architectures, and production problems like thundering herd, cache stampede, and hot key mitigation with TypeScript and Redis examples.
Designing a DNS-Based Traffic Management System: Weighted Routing, Failover Policies, and Global Load Distribution
DNS is not just name resolution. At scale, it is the first layer of traffic management, handling weighted routing, latency-based decisions, geolocation policies, and health-driven failover before a single TCP connection is established. This guide covers how it works and how to build a routing decision engine in TypeScript.
Designing a Web Crawler: URL Frontier, Politeness Policies, and Distributed Scheduling at Scale
A deep dive into production web crawler architecture covering URL frontier management, politeness enforcement, content deduplication with SimHash, distributed worker coordination via consistent hashing, and DNS caching strategies.
Building a SaaS Admin Dashboard: Role-Based Views, Audit Trails, and Real-Time Updates in Next.js
A practical guide to the admin dashboard every SaaS product needs. Covers role-based access at the component level, audit log UIs, real-time updates with SSE and React Server Components, table pagination, and filter/search patterns in Next.js App Router with TypeScript.
Building a CLI Tool in TypeScript: Argument Parsing, Interactive Prompts, and Cross-Platform Distribution
A practical guide to building production-quality CLI tools with TypeScript. Covers project setup with tsup, argument parsing with Commander.js, interactive prompts with @clack/prompts, configuration management with cosmiconfig, output formatting, error handling, testing, and distribution via npm and Homebrew.
