Web, React and Next.js, AI and RAG, and mobile. Written from production work, not tutorials about tutorials.
An MVP RAG chatbot costs $4k-$12k to build in 2026, production builds run $15k-$40k+, and running costs land at $5-$30 per 1,000 queries. Full breakdown.
AI EngineeringFinal-answer assertions keep your CI green while your agent calls the wrong tool, loops extra steps, and quietly burns budget. Here is the trajectory-scoring eval harness I run: deterministic tool mocks, six scored dimensions, and an LLM judge kept on a rubric and audit.
AI EngineeringI ran the same support-bot workload through Mem0, Letta, Zep, and LangMem and measured latency, token cost, recall accuracy, and how hard each one was to bolt on. A memory layer, an agent runtime, and a temporal knowledge graph are three different products, and the right one depends on your workload.
AI EngineeringStrict structured outputs hold ~99.9% schema compliance while plain JSON mode fails 8-15% of the time. I compare OpenAI, Claude, and Gemini with one Zod schema.
AI EngineeringMost AI agents don't need a memory vendor. Unless you need consolidation, decay, or cross-agent state, Postgres with pgvector covers memory for $0 extra.
AI EngineeringThe final MCP spec ships July 28, 2026 and removes sessions from the protocol. I migrated my production Node server; here is the exact diff and checklist.
AI EngineeringYes, you can ship private RAG on one 24GB GPU in 2026. I ran a 50-question eval: Gemma 4 26B MoE wins English corpora, Qwen3.6 27B wins multilingual.
AI EngineeringI audited my production MCP stack against the NSA's May 2026 guidance and the OX Security RCE disclosure. Here is the 12-point hardening checklist I use.
AI EngineeringPricing converged at $20/$200 and SWE-bench scores sit within a point, so workflow decides. Real cost-per-feature numbers from paid client projects.
AI EngineeringNo. I rebuilt my production SaaS pipeline as agentic retrieval: cost per query down 36%, accuracy up from 68% to 89%. Only naive top-k RAG died in 2026.
AI EngineeringI cut my reputation SaaS's LLM bill 79%, from $41.60 to $8.90 per 1,000 AI replies, using routing, prompt caching, semantic caching, and batching.
AI EngineeringOTel GenAI spans went stable in early 2026. Here is how I instrument a TypeScript agent in Node.js, track cost per trace, and alert on silent failures.
AI EngineeringYou do not need a rewrite to add AI to a SaaS. Add one endpoint beside your existing API, wire it to one workflow, stream the output, and cap token spend.
I take on a few projects at a time: web apps, AI features, and mobile. Tell me what you are working on.
