Service Level Objectives in Practice: Defining SLOs, Burn-Rate Alerting, and Error Budget Policies for Production Systems
How to define SLIs and SLOs that reflect real user pain, calculate error budgets, implement multi-window burn-rate alerting with Prometheus, and enforce error budget policies that connect reliability to engineering priorities.
Building Your Startup's AI Strategy: Identifying High-Impact Use Cases, Build vs Integrate Decisions, and Managing Investor Expectations
A practical framework for startup CTOs to evaluate AI use cases by ROI and complexity, decide when to use APIs vs fine-tune vs train, audit AI readiness, budget realistically, and communicate with investors without overpromising.
Engineering Estimation That Actually Works: Probabilistic Forecasting, Confidence Intervals, and Communicating Uncertainty
A practical guide for engineering leaders on moving beyond story points and gut-feel estimates to probabilistic forecasting using Monte Carlo simulation, reference class forecasting, and confidence intervals.
Technical Debt Assessment for Non-Technical Founders: What to Ask, What to Measure, and When to Worry
A guide for non-technical startup founders to evaluate codebase health without reading code. Covers proxy metrics like deployment frequency and bug rates, the right questions to ask your CTO, red flags that signal dangerous debt levels, and when to invest in a professional technical audit.
Designing a Digital Wallet System: Double-Entry Ledgers, Transaction Atomicity, and Balance Consistency at Scale
How to architect a digital wallet from first principles: double-entry ledger schema, ACID atomicity for transfers, concurrent balance consistency, idempotency, reconciliation, and multi-currency support with TypeScript examples and honest tradeoffs.
Designing a Real-Time Event Processing System: Complex Event Processing, Windowed Aggregations, and Pattern Detection at Scale
A practical guide to building real-time event processing systems: CEP engines, tumbling and sliding window aggregations, event pattern matching, and honest tradeoffs between Kafka Streams, Apache Flink, and lighter-weight alternatives.
Designing a Status Page System: Health Aggregation, Incident Communication, and Subscriber Notifications at Scale
A deep dive into the architecture of a production status page system: health check aggregation, incident state machines, subscriber notification fan-out, and the operational challenge of keeping your status page up when everything else is down.
Building a Form Engine in TypeScript: JSON Schema-Driven Rendering, Conditional Logic, and Multi-Step Validation
How to build a dynamic form engine that renders from JSON schema definitions, handles conditional field visibility, manages multi-step wizard state, and integrates Zod validation with resume-later persistence.
Building a Notification Center in React: Real-Time Updates, Read State, and Preference Management in Next.js

A practical guide to implementing Stripe billing in a Next.js SaaS application. Covers subscription lifecycle management, usage-based metering, webhook verification, idempotent event handling, customer portal integration, and edge cases like failed payments and mid-cycle plan changes.
Building an LLM Evaluation Harness: Automated Scoring, Human-in-the-Loop Review, and Regression Testing for Prompt Changes
Most LLM evaluation advice stops at "use LLM-as-judge." This article goes further, covering how to engineer a full evaluation harness in TypeScript with golden datasets, multi-method scoring, human review queues, and CI regression gates that block prompt regressions before they ship.
Multimodal RAG in Production: Retrieving and Reasoning Over Images, Tables, and Code Alongside Text
How to build a production multimodal RAG pipeline that handles images, tables, code, and PDFs in a unified retrieval architecture alongside text, including embedding models, chunking strategies, cross-modal retrieval, and evaluation.
