0→1 consumer platform: realtime multiplayer + marketplace throughput, leading a team of four.

Lead Full-Stack Engineer (Co-Founder); end-to-end product, frontend, backend, infra.

## Situation We needed a production consumer platform that could grow daily usage while keeping multiplayer sessions responsive and a high-volume marketplace reliable. ## Constraints Small founding engineering team, continuous shipping pressure, and mixed realtime plus transactional workloads on one product surface. ## Decisions Chose to own the full stack end to end rather than splitting product into disconnected services early. Invested in a realtime networking redesign when latency and concurrency became the bottleneck. Kept wallet/chain integrations only where they unlocked product value; they were never the primary systems story. ## Outcomes Reached 5,000+ DAU and 20,000+ WAU through iterative product and infrastructure work. Marketplace processed over one million transactions in its first year. Realtime path supported 100+ concurrent players per game with meaningfully lower latency after the redesign. Led a team of four full-stack engineers with direct CEO collaboration on technical strategy. ## Lessons Staff-level leverage came from owning the bottleneck (realtime + throughput) and the team, not from spotlighting niche domain labels. What I would do differently: introduce clearer service boundaries earlier once marketplace and realtime traffic patterns diverged.

Best for roles like: Staff roles owning realtime systems, marketplace scale, and small-team technical leadership.
