Hey devs, After spending a lot of time writing TypeScript code (and sometimes feeling more confident than I probably should), I decided to create something to help myself and others properly measure their TypeScript knowledge. So I built TS Quiz — a free interactive quiz platform focused on modern TypeScript and React + TypeScript. 125 hand-crafted questions 5 difficulty levels (Basic → Advanced)
Building a Translation Pipeline for International Contract Bidding If your company bids on international contracts, you've probably dealt with the translation bottleneck. Technical proposals need precise translation, certified documents have strict formatting requirements, and procurement deadlines don't wait for anyone. After seeing how UK public procurement translation requirements can make or
Practical post for engineers who've hit the wall where an AI proof-of-concept works on clean data but can't connect to the legacy systems that hold actual production data. Disclosure: I work at Ailoitte, which builds AI integration layers connecting legacy infrastructure to production AI. Sharing what the engineering actually looks like. AI models expect structured, consistently formatted data. Le
Originally published on oseifert.ch TL;DR: Quizlet locked the learn mode and Knowt's import extension keeps missing cards. So i built quick-cards, a Chrome extension that grabs your Quizlet set and exports it to whatever you want (txt, csv, json, pdf, printable flashcards, Anki decks, or directly to Knowt). Chrome only for now, install instructions at quickcards.oseifert.ch/install. If you are a s
Why I'm building OneSlate Calendly is great if you're a freelancer with one calendar. It breaks if you're an executive with shared calendars from your The result: my Calendly booking page often shows zero available OneSlate solves this with a simple but specific filter: only calendar_kind is primary or owned count That single insight is the core differentiator. Everything else Solo founder,
You write a detailed design doc. You paste it into your AI assistant. You wait. The output compiles. Tests pass. And yet — it's not quite what you designed. The auth middleware is in the wrong layer. The error handling pattern differs from the rest of the codebase. The field names don't match the schema. You fix it. Next task, same thing. This happens constantly, and it's not a model capability pr
Go is a compiled language — the code is converted into machine‑readable form before execution. From a beginner’s perspective, this means Go catches many errors during compilation, giving you cleaner, faster, and more predictable performance at runtime. Go is widely used for: API development CLI tools Microservices architecture Backend server. DEVOPS activity So it fits perfectly with the kind of
If you've tried building an AI agent in the last six months, you've hit the same wall: there are half a dozen frameworks, each with a different philosophy, a different API surface, and a different definition of what an "agent" even is. I spent a weekend writing the same simple agent — "read a GitHub issue, classify it as bug/feature/question, and post a comment" — in six different frameworks. This
