Vibefilter: a reviews table filtered by the statement “The customer is angry.”

Applied AI · Open-Source Filament Plugin

Vibefilter, Filtering Beyond SQL

Problem

SQL finds words, not meaning. “The customer is angry” or “the ticket is about billing” can't be written as a WHERE clause.

What I built

A Filament table filter that takes a plain-English statement and gives every row a calibrated probability, using TypeSafe's Jev model.

Result

1,000 rows scored in about a second, for a fraction of a cent. Listed in the official Filament plugin directory.

The plugin has a cost guard, live progress, a cache by content and retries for bad API days. Its public demo runs on a daily budget, with per-visitor limits and bot protection.

VoxRelay: a dictated sentence in an email, and a voice command waiting for confirmation

Applied AI · Local AI · Open-Source Linux App

VoxRelay, Offline Voice Typing for Linux

Mind your language. Or don't: it censors you anyway.

Problem

Most voice typing tools send your audio to a server. For notes, code and client work, that's a privacy problem.

What I built

Push-to-talk dictation on faster-whisper that types into any window, and voice commands that run only after you confirm them.

Result

Speaking is about three times faster than typing, and it all stays on your machine.

100% offline, on CPU or GPU, with no network calls and no telemetry.

I use it every day.

It's multilingual: dictate in English, Hungarian or dozens of other languages, even mixing them in one sentence. A custom dictionary steers it toward names and jargon, a blocklist drops hallucinated sentences, and an unknown phrase can be taught a new command on the spot. Approved commands run in one reusable terminal, with live output and a log.

NordWoodArt e-commerce platform

E-Commerce Platform

NordWoodArt, Artisan Wooden Wall Art

Problem

Showing hundreds of product variants and color combinations was slow, expensive, and hard to manage manually.

What I built

A Laravel + Filament back office and an automated rendering pipeline that generates product visuals and manages variants.

Result

New variants can be prepared in hours instead of days, reducing costs and enabling fast decisions before producing anything.

The pipeline renders each product in Blender, then converts, compresses and resizes the images for fast pages and good SEO.

  • Catalog with size and color variants and per-variant pricing
  • Orders from checkout to delivery: Stripe, Foxpost, GLS and MPL, with emails at each step
  • Coupons with date windows, usage caps and product or category scope
  • Visitor and search analytics without third-party tools

Public Sector Information System

Government Funding Platform

Context

One of the most critical national public administration platforms, processing government funding programs for 100,000+ users.

My role

Senior Software Developer, developing and testing a large-scale government information system since 2017.

Scale

100,000+ users across the platform. Load and performance testing with Apache JMeter.

Built and tested enterprise applications for a system that has to run reliably for years.

IoT & Hardware

Retail Loyalty Terminal System

Problem

A retail chain needed a loyalty and rewards system across 24 locations with no off-the-shelf solution fitting their requirements.

What I built

Raspberry Pi–based terminals with custom 3D-printed housings, dual displays, barcode and RFID card readers, and remote deployment.

Result

24 locations nationwide with personalized promotions, store-specific rewards, and anonymous card distribution on first use.

Full hardware and software development from prototype to production. Custom 3D-printed terminal housing, dual display setup (customer screen + merchant screen), point collection and redemption with store-specific and customer-specific rewards. Built with Python, immutable OS (SquashFS root, tmpfs overlay), and remote application deployment.

How a project runs

How I Work

Most projects go through the same five steps.

  1. 01

    Understand the goal

    I find out what the system has to do, who will use it and where the risks are. Scope is agreed before any code is written.

    You: Bring input from the people who will use it daily.

  2. 02

    Design the structure

    I map how data moves through the system: structures, user roles, validation. Changes are cheap at this stage.

    You: Check the structure against how your business really works.

  3. 03

    Build in short rounds

    I deliver working features in short rounds, with tests running on every change. You test each round against your real workflow.

    You: Test each round and tell me what feels off.

  4. 04

    Test before launch

    Before launch I run end-to-end browser tests on the full workflow, including roles, edge cases and data consistency.

    You: Let your team run their real tasks on it.

  5. 05

    Hand over cleanly

    Clean code, clear structure and documentation where it matters, so another developer can pick it up later.

    You: Name someone who owns the system after handoff.

Who I am

About

Andras Horvath

I've worked in IT for over 25 years. I started in system administration, running the Hungarian IT infrastructure of a multinational company: a headquarters and four branch offices, with Windows servers, Active Directory and the network.

Then I moved to software. I developed many online shops, back-office systems and service apps. I also worked on CRM platforms and industrial safety software, and built a loyalty terminal system that ran in 24 shops. Since 2017 I've been a senior developer on a government funding platform with 100,000+ users.

I publish open-source work too: Vibefilter, a Filament plugin listed in the official directory, and VoxRelay, an offline app that types what I dictate and asks for confirmation before it runs a spoken command. I use it every day.
