Heavy equipment / marketplace / B2B
Requests & offers matching platform (heavy-equipment marketplace)
A B2B "requests exchange": a core that automatically matches demand and supply with proactive notifications (email and PWA push). I built the product and its core from scratch; the architecture survived a market pivot without a rewrite.

Before a fragmented rental market and slow manual search — you had to monitor listings constantly
After automatic matching of requests and offers with proactive alerts — ~1,000 organizations and ~3,000 users on the platform

Key outcome
The platform replaced manual search with automatic matching and survived a change of market without a rewrite.
Context
The rental market was fragmented: demand and supply lived separately, and matches had to be found by hand, constantly monitoring listings. The project started in property rental, then the owner pivoted it to heavy equipment and transport.
The key challenge
It needed a core that finds matches on its own and notifies about them, and an architecture able to survive a change of market. The cost of getting it wrong was high: the wrong foundation would mean rewriting the whole platform when the business pivoted.
My role
Lead developer and architect from the project’s founding. I designed the matching core from scratch and led a cross-functional team (engineering, analytics, design), carrying the product through a change of vertical while keeping its core intact.
The solution
Instead of monitoring listings by hand, the platform automatically matches demand with supply and notifies both sides by email and mobile push. Around this core: posting requests and offers, search, a map and communication between parties; rental and sale in one ecosystem, with integrations into ERP, telephony, payments and SMS.
Results
The platform has run since 2022 and keeps evolving, with around 1,000 organizations and some 3,000 users. The value is direct: equipment or a renter is found faster, and automatic notifications replace manual monitoring. The architecture survived the change of market without a rewrite.
Why this matters for my clients
This experience shows that I design systems that survive a strategic pivot of the business rather than falling apart at the first change of course.
