Projects

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.

I run this business myself, so the platform is built around real operations: catalog management, inventory, orders, analytics, and fulfillment. The automated pipeline generates Blender renders, then handles conversion (WebP/JPEG), compression, responsive sizing, and metadata, tuned for Core Web Vitals and SEO.

E-Commerce Core

Product catalog with attribute-based variant system (size × color combinations), dynamic pricing (base + variant addon), and responsive image galleries with 18 conversions per upload.

Order Management

Full order lifecycle (received → approved → shipped → delivered), Stripe Checkout integration with HUF currency, Foxpost/GLS/MPL shipping options, and automatic email notifications at every stage.

Coupon Engine

Fixed and percentage discounts with date-based activation windows, per-customer usage caps, first-order restrictions, and product/category scoping.

Guest Analytics

Session-based visitor tracking, landing page analysis, referrer source detection, search query monitoring, and no-result gap identification, all without third-party analytics.

Bilingual Support

Full Hungarian + English content (data model, UI, routing). Domain-based locale switching with user preference override.

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 I deliver results

How I Work

I approach every project as a system. Most projects move through the same five phases.

Technology is a tool. Structure is the foundation.

Strategic Understanding

Clarify the objective.

I start by understanding what the system actually needs to do. Scope, priorities, and potential risks get defined before any code is written.

What business outcome is expected? Who interacts with the system, and under what constraints? Where can complexity appear later? These are the questions that shape everything that follows.

Well-defined boundaries early prevent architectural debt.

Your role: Gather input from the people who will use the system daily. The more real-world context you bring to the table, the fewer surprises we'll face later.

System Architecture

Design the core.

Before writing any code, I map out how data flows through the system. Every structural decision made here saves hours of rework later.

Data structures, domain boundaries, user roles, validation logic, scalability. All defined upfront so the architecture holds up as the project grows.

A clear architecture makes development predictable and maintainable.

Your role: Review the proposed structure and challenge anything that doesn't match your reality. Adjustments here are fast, simple, and part of the process.

Controlled Execution

Development follows structure.

I deliver in focused iterations. Each round produces working functionality you can test against your actual workflow. Validation rules, authorization policies, and data integrity constraints are built in from the start. Automated feature tests run with every change.

Early feedback keeps the cost of change low. That's the entire point of iterative delivery.

Your role: Test each delivery. Try to break it. If something feels off, say so. Changes are still possible, but they may carry scope and timeline implications.

Quality Assurance & Hardening

A system that works is not the same as a system you can rely on.

Before anything goes live, I run end-to-end browser tests against the full workflow. Boundary conditions, role-based access, data consistency, and the edge cases that real users always find.

Production issues are expensive. Testing is not.

Your role: Let your team run through their actual tasks. The most valuable feedback comes from real usage.

Sustainable Delivery

Built to remain understandable months or years later.

Clean, maintainable code. Logical structure that speaks for itself. Documentation where it matters. A foundation that allows growth without rewrite.

I build systems meant to last.

Your role: Designate someone who owns the system after handoff. I'll make sure they understand the architecture and key decisions. A well-built system still needs someone who cares about it.

Online cash register reseller platform

“Andras built us a backend system that lets me see any analytics about our customers within a minute. Since then, I can focus on strategic management tasks, because the website works 24 hours a day, on its own, producing new customers. We became the leading cash register reseller in Hungary with an automated platform handling communication, scheduling, and regulatory compliance, exceeding even our own goal of doubling the customer base.”

“If I could have one wish for my business, it would be to always have professionals like Andras around — that's the key to our success.”

Loyalty & coupon terminal system

“The software Andras developed handles a high volume of customers and transactions reliably and transparently. He always focused on making the system as easy to use as possible, training new users was effortless.”

Hazardous area compliance software

“I would recommend Andras anytime as a backend developer. His job was penetration testing and developing new functions for our industrial safety compliance system.”

Who I am

About

I’ve been working in IT for over 25 years, progressing from system administration to full-stack development. Early in my career I managed the Hungarian IT infrastructure of a multinational company: a headquarters and 4 branch offices, covering Windows servers, Active Directory, networking, and operations, where stability, documentation, and discipline were essential.

That background still shapes how I build software today. I focus on systems that remain maintainable under pressure and understandable months or years later.

Over the years I’ve worked on CRM platforms, industrial safety software, IoT hardware integrations, and public-sector systems handling large-scale operational workflows. These environments required precision, auditability, and long-term reliability.

Running my own e-commerce business adds another layer: I build and operate the same kind of systems I deliver to clients. Every automation, pipeline, and dashboard I create is grounded in real business constraints: time, cost, and repeatability.
