We are now running demos and tests with a small group of invited teams.https://amfelt.com/blog/why-we-are-building-amfelt/Sun, 01 Nov 2026 00:11:00 +0000https://amfelt.com/blog/why-we-are-building-amfelt/A CFO asks the whole company to build with AI, while a modest pilot to collect raw vessel data sits blocked. Why we're building Amfelt for the gap in between.https://amfelt.com/blog/coordinating-parallel-agents/Sun, 01 Nov 2026 00:10:00 +0000https://amfelt.com/blog/coordinating-parallel-agents/A commit in August staged one agent session's uncommitted work into another session's change. How we responded with Git worktrees, a guard hook, shared planning documents, a GitHub issue tree, and handovers between sessions.https://amfelt.com/blog/type-casting-is-a-pipeline-step/Sun, 01 Nov 2026 00:09:00 +0000https://amfelt.com/blog/type-casting-is-a-pipeline-step/At a wholesaler moving toward dbt, I found typed source columns arriving as strings in Snowflake. The migration showed how much transformation code depended on those conversions.https://amfelt.com/blog/htmx-instead-of-react/Sun, 01 Nov 2026 00:08:00 +0000https://amfelt.com/blog/htmx-instead-of-react/Why a team with Go and Hugo experience built a CRUD-shaped control plane from server-rendered HTML fragments instead of React, what that costs us, and the kind of app where we would choose differently.https://amfelt.com/blog/why-our-platform-is-a-modular-monolith/Sun, 01 Nov 2026 00:07:00 +0000https://amfelt.com/blog/why-our-platform-is-a-modular-monolith/Why a small team with a fixed stack chose one Go binary per app on one Postgres instead of microservices, what that costs, and the triggers that would make us split.https://amfelt.com/blog/gating-a-static-site-with-go/Sun, 01 Nov 2026 00:06:00 +0000https://amfelt.com/blog/gating-a-static-site-with-go/How we gave a Hugo site per-user access control without giving up static output: a small Gin server, Hanko for sign-in, and the whole site embedded in the binary.https://amfelt.com/blog/markdown-knowledge-base-for-ai-development/Sun, 01 Nov 2026 00:05:00 +0000https://amfelt.com/blog/markdown-knowledge-base-for-ai-development/AI-assisted development produces documentation faster than anyone can file it. Plain Markdown in the repository, rendered by a static site generator, turns that pile into a knowledge base for both people and agents.https://amfelt.com/blog/perfect-sql-wrong-answer/Sun, 01 Nov 2026 00:04:00 +0000https://amfelt.com/blog/perfect-sql-wrong-answer/Three teams at a national telco counted connections three different ways. That experience, and MotherDuck's data-preparation benchmark, made me question what an agent needs beyond valid SQL.https://amfelt.com/blog/make-your-pipelines-deterministic/Sun, 01 Nov 2026 00:03:00 +0000https://amfelt.com/blog/make-your-pipelines-deterministic/An LLM changed my build check until a failing Hugo build looked successful. That experience shaped how I think about AI-generated pipeline code and the checks it must pass.https://amfelt.com/blog/every-warehouse-needs-history/Sun, 01 Nov 2026 00:02:00 +0000https://amfelt.com/blog/every-warehouse-needs-history/My first engagement as an independent consultant started with a week of manually recovering failed warehouse loads, and a CFO whose numbers moved between Monday and Thursday. The root cause was a warehouse with no history, which is far more common than it should be.https://amfelt.com/blog/understanding-your-data-platform/Sun, 01 Nov 2026 00:01:00 +0000https://amfelt.com/blog/understanding-your-data-platform/An incomplete source inventory sent me into years of integration code before I could plan a global warehouse. What that work taught me about documenting a data platform.https://amfelt.com/blog/data-tools-solving-wrong-problems/Sun, 01 Nov 2026 00:00:00 +0000https://amfelt.com/blog/data-tools-solving-wrong-problems/Four colleagues praised our demo. The fifth reviewer, a system integrator we barely knew, questioned the complexity and the problems we had chosen to solve. We had to reconsider what would make the platform useful to a data team.
