Systems that
do real work.
I turn awkward data and repetitive business processes into small, dependable systems—automations, dashboards, data pipelines and AI-assisted tools.
Built by Laszlo Farkas. No agency theatre. No invented results.
Selected systems / 01—05
Proof, not promises.
Real builds presented honestly: what they solve, how they work, and what I learned when reality disagreed with the plan.
Lead intelligence · n8n · Supabase
The machine worked.
The business model didn't.
A candid teardown of Virevia's EV lead engine: a technically capable system, a commercially failed offer, and the lessons worth keeping.
Public data · Python · React
Contract intelligence pipeline
Monitors public opportunities, classifies compliance signals and turns raw notices into a usable review queue.
Agent workflow · Python · APIs
Autonomous content engine
A configurable nine-stage pipeline from idea to render, human approval, publishing and feedback.
FastAPI · Stripe · WhatsApp
Order-to-operations workflow
A deliberately small service stack: checkout, webhook, order creation and operational notifications.
React · TypeScript · interaction design
Trace: a visual browsing game
A playful demonstration of interface design, state management and product thinking.
Public utilities
Useful before hireable.
Small browser-based tools for cleaning data and estimating whether an automation is worth building. Free, private-by-design and no account required.
Working principle
“A polished demo is nice. A system that survives real inputs, awkward edge cases and human review is better.”
Virevia Lab documents both—the interface people see and the engineering decisions underneath it.
Have a messy process?
Show me the input.
I’ll show you the system.
