Thinking on AI systems, architecture, and the craft of building things that work.
AI Integration Services: What 'Bolt AI Onto Existing Systems' Actually Costs in 2026
Bolting AI onto an existing SaaS typically costs 5k–80k per feature — and the model API bill is rarely the expensive part. A phase-by-phase breakdown of what real AI integration services cost in 2026.
EngineeringHow to Make an App in 2026: The AI-Native Stack We Actually Ship With
The 2026 stack we ship every new POC and MVP on: edge functions, React Server Components, passkey auth, Claude MCP for AI features, and AI sub-agents for ops. Cuts MVP delivery time by 30-50%.
EngineeringWhy We Don't Use Vector Search for Our AI's Knowledge Base
For a curated KB under ~500 entries, a hand-written lean index outperforms RAG, embeddings, and re-ranking. The LLM is the retriever — and it reads English better than any embedding model reads vectors.
EngineeringLarge-Scale Web Scraping: How We Built an On-Demand Proxy Fleet to Collect 1.1M Records
When Akamai blocked our fixed proxy pool, we used the Linode API to spin up 37 disposable VMs as a fresh proxy fleet — and scraped 1.1 million records from a bot-protected government portal overnight.
EngineeringHow Negative Constraints Fixed Our Multi-Step LLM Video Pipeline
Sequential LLM calls converge on the same output. A global shot plan with prohibited state changes — telling each step what it cannot do — turned disconnected segments into coherent visual narratives.

EngineeringWhy We Generate Audio First in AI Video Pipelines (And Why You Should Too)
AI video models don't accept target durations. AI audio models don't either. But audio can be precisely measured after generation using word-level timestamps.
EngineeringWhy We Stopped Using Images to Generate AI Music Videos (And What We Use Instead)
We abandoned image-to-video pipelines for AI music video generation and switched to pure text-to-video with Seedance 2.0. Here is why forensic text prompting beats reference images for multi-clip coherence.
EngineeringWhy the AI Model You Pick Barely Matters (And What Actually Does)
Teams obsess over model benchmarks when the real leverage is in the engineering layer. Structured outputs, fallback chains, and model-agnostic architecture matter more than which LLM you pick.
