Delivering OpenH2H from requirements to production
I coordinated delivery of a B2B digital-product marketplace for a client without an internal engineering team. Clear scope and versioned requirements kept a 6-person delivery team aligned through an approximately 2.5-month production launch.

Context
The client needed an accelerated launch but could not provide an engineering counterpart. Business requirements had to become specifications the delivery team could implement and decisions the client could approve.
My role and the team
I owned scope, planning, timeline, requirements and team and vendor coordination, including UAT coordination and release approval. The delivery team executed coding, testing and deployment. I was not responsible for sales or customer acquisition.
Decisions and trade-offs
Versioned requirements as the shared source of truth
Requirements and changes were confirmed before implementation, then progress was communicated in plain language the client could review. That closed the gap between business decisions and engineering work without asking the client to read code or technical specifications.
Outcomes
Initial production launch in approximately 2.5 months, with 10+ external integrations including SNAP Banking. The platform now carries 400K+ real production transactions per day: about 60% migrated from established H2H connections and about 40% brought by the sellers and buyers who joined. That is platform context, not a sales or load-test claim.
