What a spec should contain, where it lives, and when vibe coding is still the right call. mihajlop98@gmail.com (Mihajlo Petrovic) Engineering AI Sun, 30 Aug 2026 10:00:00 GMT https://mihajlopetrovic.me/blog/ai-agents-in-practice-bmad-mcp-sourcekit https://mihajlopetrovic.me/blog/ai-agents-in-practice-bmad-mcp-sourcekit A practical look at the plumbing around AI coding agents: the BMAD method for planning, MCP for tooling, and SourceKit-LSP for real Swift code intelligence - what each one does, how to set it up, and where it actually pays off. mihajlop98@gmail.com (Mihajlo Petrovic) Engineering AI Fri, 28 Aug 2026 10:00:00 GMT https://mihajlopetrovic.me/blog/local-llms-apple-silicon https://mihajlopetrovic.me/blog/local-llms-apple-silicon How much RAM you actually need, what quantisation costs you, which tools are worth installing - and a clear answer on where a laptop model beats an API and where it is not remotely close. mihajlop98@gmail.com (Mihajlo Petrovic) Engineering AI Fri, 14 Aug 2026 10:00:00 GMT https://mihajlopetrovic.me/blog/ai-in-regulated-fintech https://mihajlopetrovic.me/blog/ai-in-regulated-fintech What changes when the software is a bank's: data classification and residency, audit trails, the hard line between drafting and deciding, model upgrades as change management - and why internal developer tooling is where to start. mihajlop98@gmail.com (Mihajlo Petrovic) Engineering FinTech AI Tue, 04 Aug 2026 10:00:00 GMT https://mihajlopetrovic.me/blog/ai-code-review-in-practice https://mihajlopetrovic.me/blog/ai-code-review-in-practice An honest breakdown of where an AI reviewer genuinely outperforms a tired human, where it is blind by construction, and the three configuration mistakes that make a team mute the bot in week two. mihajlop98@gmail.com (Mihajlo Petrovic) Engineering AI Tue, 21 Jul 2026 10:00:00 GMT https://mihajlopetrovic.me/blog/evals-testing-llm-features https://mihajlopetrovic.me/blog/evals-testing-llm-features You cannot unit-test an LLM feature, so most teams ship prompt changes on vibes and break things silently. How to build a golden set, assert cheaply before reaching for a judge model, and wire it all into CI. mihajlop98@gmail.com (Mihajlo Petrovic) Engineering AI Fri, 10 Jul 2026 10:00:00 GMT https://mihajlopetrovic.me/blog/llm-feature-angular-app https://mihajlopetrovic.me/blog/llm-feature-angular-app Prototyping an AI feature takes an afternoon; shipping one takes longer, and almost none of the extra time is prompting. Streaming with SSE, cancellation, rate limits, caching and cost control - with the Angular and Node code. mihajlop98@gmail.com (Mihajlo Petrovic) Engineering AI Frontend Tue, 30 Jun 2026 10:00:00 GMT https://mihajlopetrovic.me/blog/swiftui-for-angular-developers https://mihajlopetrovic.me/blog/swiftui-for-angular-developers Coming to SwiftUI from Angular, the concepts map more cleanly than you expect - and the places they do not map are exactly where you lose a week. Here is what transfers, what traps you, and how to pick the right state wrapper the first time. mihajlop98@gmail.com (Mihajlo Petrovic) Engineering iOS Fri, 12 Jun 2026 10:00:00 GMT https://mihajlopetrovic.me/blog/rag-vs-long-context https://mihajlopetrovic.me/blog/rag-vs-long-context Million-token context windows and prompt caching changed the maths. How to tell whether your corpus needs a real retrieval pipeline or just needs to be pasted into the prompt - and how to build retrieval properly if it does. mihajlop98@gmail.com (Mihajlo Petrovic) Engineering AI Fri, 22 May 2026 10:00:00 GMT https://mihajlopetrovic.me/blog/daily-ai-workflow-terminal https://mihajlopetrovic.me/blog/daily-ai-workflow-terminal No chat window, no magic - a concrete account of how I actually use coding agents day to day: instructions files, plan-first prompting, sub-agents, hooks, worktrees, and the things I deliberately never delegate. mihajlop98@gmail.com (Mihajlo Petrovic) Engineering AI Sat, 09 May 2026 10:00:00 GMT https://mihajlopetrovic.me/blog/building-your-first-mcp-server https://mihajlopetrovic.me/blog/building-your-first-mcp-server MCP lets you write one integration that any AI client can use.
