A collection of tools, guides, projects and writing I’ve created around digital business, marketing, technology, money and modern life.
Small tools, AI experiments, practical guides and side projects. Most of them began as a problem of my own.
LinkedIn, minus the noise.
A Chrome extension that filters your LinkedIn feed so you can focus on posts from people you actually know.
What it hides
It started in my own feed. Promoted posts, suggestions and viral posts from strangers kept pushing aside updates from colleagues and friends. Instead of scrolling past them every day, I built a filter. Everything runs in the browser: no data is collected or sent anywhere.
Small, working software. Each one started as something I needed myself.
A quieter LinkedIn feed.
Hides promoted posts, strangers and sidebar clutter, so only your first-degree network is left. Switch it off with one click.
Where I try new technology on real professional problems, and keep what turns out to be useful.
Ask marketing questions. Get practical answers.
An AI assistant designed to help marketers navigate advertising specifications, formats and platform requirements. It is trained on ad formats and keeps the general abilities of the OpenAI model underneath, so you can also ask for copy ideas or campaign structures.
AI applied to a real professional problem: the hour lost searching help pages for one image size.
What aspect ratio should a vertical video ad use?
9:16, usually 1080 × 1920 px. Keep text and logos away from the top and bottom edges, where the app’s interface sits. Check the platform’s current specs before you export.
And for a square feed placement?
The handbooks I wish I’d had: short, specific, made to be kept open next to the work.
Advertising specifications without the headache.
A practical reference designed to make advertising formats, specifications and recommendations easier to navigate. Specs change often, so it’s a starting point to check against each platform’s documentation.
Inside
Not everything here is about marketing. Curiosity doesn’t stay in one category.
Making personal finance easier to understand.
A project about personal finance, designed to make money, investing and financial decisions more accessible. No jargon, no gurus, and no promises of getting rich in three weeks.

I like making things that solve small problems.
Sometimes that means writing an article. Sometimes it means building a tool. Sometimes it means experimenting with AI. Sometimes it means creating a guide that I wish existed already.
The projects are different, but the motivation is usually the same: make something useful.
Curiosity turning into creation, in five steps that repeat.
Each tool above solves one specific problem. For example, OnlyFirst cleans up your LinkedIn feed, while the ads guide gathers specs in one place. Also, the chatbot answers quick questions about formats.
New marketing resources are added when a real need appears. For example, the Chrome extension started as a personal fix for a noisy feed.
In short, these marketing resources are designed to save time. Therefore, pick the one that fits your current task and come back for new additions.
