Notes on what I build: frontend, fullstack, AI and Linux.https://portfolio.rossmel.com/en-ushttps://portfolio.rossmel.com/en/blog/manga-13-gb-to-2-7-gb/https://portfolio.rossmel.com/en/blog/manga-13-gb-to-2-7-gb/A series of scanned manga weighed 800 MB per volume. I compared JPEG, WebP and AVIF on real pages, found the point where the screentone breaks down and brought it to a fifth of the size.Sat, 10 Oct 2026 00:00:00 GMThomelabpythonperformancehttps://portfolio.rossmel.com/en/blog/transcribe-local-transcription-in-the-terminal/https://portfolio.rossmel.com/en/blog/transcribe-local-transcription-in-the-terminal/I needed to turn a voice note into text without uploading it anywhere. That same night the ten-line script became an interactive CLI with subtitles, tests and an MIT license.Sat, 10 Oct 2026 00:00:00 GMTpythonaiopen-sourceclihttps://portfolio.rossmel.com/en/blog/notebook-notes-with-memory/https://portfolio.rossmel.com/en/blog/notebook-notes-with-memory/It started as a two-day experiment so I would stop losing my university notes. Two months later I rebuilt it measuring everything, kept it running for free and released the code under the MIT license.Wed, 07 Oct 2026 00:00:00 GMTairagopen-sourcenodehttps://portfolio.rossmel.com/en/blog/home-media-center-with-jellyfin/https://portfolio.rossmel.com/en/blog/home-media-center-with-jellyfin/How I built Selflix, my Jellyfin media center on a modest home server: Docker, the folder structure Jellyfin expects, access from outside without opening ports, per-person accounts and the pitfalls that cost me hours.Sat, 26 Sep 2026 00:00:00 GMThomelablinuxdockerhttps://portfolio.rossmel.com/en/blog/long-running-llm-jobs/https://portfolio.rossmel.com/en/blog/long-running-llm-jobs/Analyzing a contract clause by clause can take minutes. In AdvAI I solved it with a model pool that respects each provider's limits, a worker that survives restarts and Server-Sent Events to show progress.Thu, 24 Sep 2026 00:00:00 GMTaillmpythonbackendhttps://portfolio.rossmel.com/en/blog/an-ai-agent-that-runs-my-server/https://portfolio.rossmel.com/en/blog/an-ai-agent-that-runs-my-server/My homelab is maintained by an agent (OpenClaw) running 24/7. What makes it reliable isn't the model: it's memory written in Markdown, explicit red lines and procedures with success criteria. Here's how I organized it.Wed, 23 Sep 2026 00:00:00 GMTailinuxhttps://portfolio.rossmel.com/en/blog/anonymizing-contracts-before-calling-an-llm/https://portfolio.rossmel.com/en/blog/anonymizing-contracts-before-calling-an-llm/In AdvAI no name, ID number or tax ID leaves the machine: a rule-based anonymizer swaps them for stable placeholders and the system restores them in the answer. How it works and why I didn't use AI for it.Tue, 22 Sep 2026 00:00:00 GMTaillmprivacypythonhttps://portfolio.rossmel.com/en/blog/thesis-pdfs-ai-extraction-and-memory/https://portfolio.rossmel.com/en/blog/thesis-pdfs-ai-extraction-and-memory/In SGPG, my university's thesis management system, every PDF is processed in the browser: deterministic rules where possible, an LLM where it pays off and heuristic fallbacks. Plus a viewer that only draws the visible pages.Mon, 21 Sep 2026 00:00:00 GMTaillmnextjsperformancehttps://portfolio.rossmel.com/en/blog/switching-bootloaders-without-fear/https://portfolio.rossmel.com/en/blog/switching-bootloaders-without-fear/For rOS, my flavor of Arch, I replaced GRUB with Limine without risking the boot: install it side by side, test it on a single reboot and promote it only if it works. Idempotent scripts, pacman hooks and atomic copies to the ESP.Sat, 19 Sep 2026 00:00:00 GMTlinuxhttps://portfolio.rossmel.com/en/blog/offline-first-electron-sqlite/https://portfolio.rossmel.com/en/blog/offline-first-electron-sqlite/Link'u records meter readings and issues bills for a rural community where the internet isn't guaranteed. SQLite as the source of truth, all logic in the main process, rates frozen on every bill and AES-256-GCM encrypted backups.Fri, 18 Sep 2026 00:00:00 GMTelectronreactsecurityhttps://portfolio.rossmel.com/en/blog/citizen-report-map-with-react-leaflet/https://portfolio.rossmel.com/en/blog/citizen-report-map-with-react-leaflet/At the Hackacom 2023 hackathon we built Canasta: a map where neighbors report problems in the city and others join in to fix them. I go over the real code, the classic Leaflet icon bug and what I'd change three years later.Thu, 17 Sep 2026 00:00:00 GMTreactfrontendhttps://portfolio.rossmel.com/en/blog/coding-before-and-after-ai/https://portfolio.rossmel.com/en/blog/coding-before-and-after-ai/I learned the old-school way, and we only brought AI into our work during my last year at WANT. What changed, what didn't, and how I decide when to let AI move fast and when to review with a magnifying glass.Wed, 16 Sep 2026 00:00:00 GMTaicareerhttps://portfolio.rossmel.com/en/blog/stopping-an-llm-from-inventing-legal-citations/https://portfolio.rossmel.com/en/blog/stopping-an-llm-from-inventing-legal-citations/In AdvAI, my capstone project, the model doesn't write legal citations: it only picks from real sources and the system inserts the verbatim text. That's how I went from "sounds right" to verifiable citations.Tue, 15 Sep 2026 00:00:00 GMTaillmragpythonhttps://portfolio.rossmel.com/en/blog/portfolio-and-resume-from-one-file/https://portfolio.rossmel.com/en/blog/portfolio-and-resume-from-one-file/This site and my PDF resume come from the same data file. Astro, GSAP animations driven by attributes, a WebGL shader with a CSS plan B, a resume that passes ATS filters and a subdomain solved with 10 lines at the edge.Sun, 13 Sep 2026 00:00:00 GMTfrontendperformance
