Top 5 Desktop App Frameworks for JavaScript Developers

If you’re a JavaScript developer thinking about building a desktop app (maybe even a cross-platform one), your first instinct might be to pick Electron. But it’s no longer the only option. There are now several solid frameworks, each with different trade-offs in performance, bundle size, native integration, and overall developer experience. I wrote a quick breakdown of 5 modern desktop app framewo...

I Built an Open-Source Platform Foundation for Accounting-Centric Business Apps

The problem I kept running into Every serious line-of-business project I worked on eventually forced me to solve the same hard problems from scratch. Not the fun architectural problems. The tedious, load-bearing ones that every business system needs but most general-purpose frameworks deliberately do not provide: A document model with lifecycle, posting, and reversal An accounting e...

The payments inversion — building a Lightning revenue-share loop where the app pays the user

In the last post I argued that Stripe — and the card network underneath it — can’t serve certain payment shapes, no matter how good the developer experience around it gets. Sub-dollar payments don’t work. Agent-to-agent payments don’t work. Today’s post is about a third shape that breaks on the same rails, and the most interesting one to me, because it’s an inversion of how almost every app on the...

How to Build an AI Agent for Market Research with a Real Browser

Most AI market research starts too late. A founder, marketer, or product manager opens a blank chat box and asks: Analyze this market. Tell me the customer pain points. Find competitors. Suggest positioning. The model can produce a polished answer. But if the agent has not read the market first, the answer is usually built on stale knowledge, generic assumptions, and whatever the prompt happe...

VOMPECCC from Scratch: Picking Fruits and Veggies with ICR

"This is the fourth post in a series on Emacs completion. The first argued that Incremental Completing Read (ICR) is a structural property of an interface rather than a convenience feature. The second broke the Emacs substrate into eight packages (collectively VOMPECCC) each solving one of the six orthogonal concerns of a complete completion system. The third walked through spot, a ~1,100-lin...

Structured-Prompt-Driven Development (SPDD)

LLM programming assistants have demonstrated considerable value, but mostly with individual developers. The internal IT organization in Thoughtworks has been using them for their teams and have developed a method and workflow called Structured Prompt-Driven Development (SPDD).

Stop bundling SheetJS for simple Excel exports: a 5 KB alternative

TL;DR I open-sourced mini-xlsx, a one-function, zero-dependency XLSX builder for the browser. Around 5 KB minified. No SheetJS, no ExcelJS, no JSZip. It writes real .xlsx files that open cleanly in Excel, LibreOffice Calc, Google Sheets and Apple Numbers. If your only requirement is to output Excel files (no reading, no formulas, no charts), you almost certainly do not need a 600 KB li...

Preparing for data engineering interviews can feel overwhelming, especially when you’re trying to figure out the best way to approach data engineering interview prep… It’s not just SQL or Python; it’s data modeling, pipelines, system design, and the ability to explain your thinking clearly under pressure. Most people don’t fail because they didn’t study enough; they fail because they approached...

Is Building in Public Overrated? Ask Me Again in a Year.

The promise I started writing about my SaaS launch before I launched it. Day counters. Screenshots. “I’m shipping X today.” The indie hacker playbook, pretty much verbatim. The promise behind building in public is simple: you share the process, people get invested, and by launch day you have an audience rooting for you. A waitlist that converts. A community that shares your links. That was the...

Built a CV builder specifically for developers in 3 weeks — would love feedback

Most CV builders treat GitHub as an afterthought. readme.cv pulls your repos automatically, gives you templates that don't get destroyed by ATS parsers, and has an AI coach that reads a job posting and tells you what to change. Stack if you're curious: Next.js 16, Supabase, Stripe, React PDF, Claude Haiku. It's free to build your CV, €5/month to download. Still rough around the edges but functio...

How I used Gemini CLI to orchestrate a complex RAG migration

Building a complex, multi-phase cloud project like a RAG migration is as much about orchestration as it is about code. You have to manage infrastructure (Terraform), backend services (Python), frontend UI (Next.js), data pipelines (BigQuery/AlloyDB), and documentation - all while maintaining a consistent technical strategy. Standard IDE completions are great for snippets, but they lack the system...
