Diathermiki
Connecting the public face of an energy business with the people and systems behind it. A Lineweb collaboration that has evolved since 2019.
Selected work and products
I build across brands.
The responsibility stays personal.
My work ranges from client delivery to first-party products. Each name has a distinct role and a shared foundation: practical value, clear technology and continuity after launch.
A closer look
The story
behind the work.

Andrew's ability to quickly bring our ideas to life and his consistent support have been invaluable. He's fast, reliable, and always ready to help. Working with him has been a pleasure, and we highly recommend him for his professionalism and expertise.
We needed a mission-control center, not just a website. LineWeb engineered a digital nervous system that connects our entire fleet with a global network of brokers. From real-time partner syncs to automated financials, this platform is the engine of our growth.
I wanted something that truly reflected the standard of my practice — not a generic medical template. LineWeb understood immediately. The result is dark, premium, and exactly the tone I was after. Every detail — from the color palette to the page structure — mirrors the aesthetic and precision I demand in the clinic. Outstanding collaboration, outstanding result.
The new website is super clean and exactly what we needed. The dashboard makes managing reservations effortless, and our sales have noticeably increased. LineWeb perfectly captured our brand colors and delivered a premium experience.
Since 2016, Lineweb has been our digital partner. Thanks to their SEO strategy, we rank #1 for dance schools in Thessaloniki. Their social media marketing and graphics have completely transformed our brand image.
For over 3 years, LineWeb has handled our entire digital presence. From our beautiful website to our daily social media marketing, their consistency and creativity have been key to our restaurant's continued success.
Public work
Some of the work
stays open.
Most client systems remain private. When a tool can be useful beyond one project, I publish it, document it and contribute focused improvements back to the software everyone else depends on.
View @drewmt on GitHubLineWeb Social
A self-hosted foundation for modern communities and social products, built in public with privacy, moderation and product ownership in mind.
Restaurant Orders for WordPress
A self-hosted restaurant menu and ordering plugin with QR flows, Stripe support, no commissions and no paid feature gates.
Withdrawal for WooCommerce
A focused WooCommerce workflow for electronic contract-withdrawal statements and timestamped customer receipts.
Upstream contributions
I give back to the software
this work runs on.
Every project here runs something I depend on. When I hit a real bug or a missing piece while building for a client, I fix it upstream instead of patching around it locally, so the fix reaches everyone using it and not only me.
This is not a finished list. It grows whenever the work makes something worth fixing, and every item links to the merged pull request.

03 / WHAT STAYS CONSTANT
A product needs a reason to exist before it needs a roadmap.
I do not present prototypes as mature products, and I do not claim work I cannot support. The public profile should follow the real work, not invent it.
