Arman Mamyan

I work with fintech teams building wallets, payment rails, stablecoin infrastructure, cards, identity and digital-asset products — from architecture and provider decisions through implementation and launch.

  Jan 2026 — Present

  Developer relations, solutions engineering and integration delivery for Moca Network's AIR Kit — the identity, fintech and loyalty SDK for platforms.

  • Solutions engineering — partner with business development through the deal cycle: technical discovery, feasibility assessment, architecture proposals, live demos and proof-of-concept builds that turn partner requirements into concrete integration designs.
  • Integration engineering — work directly with partner engineering teams from kickoff through launch: scoping the right path (account-only, credential-only or full-stack), reviewing implementations, debugging against the SDK and unblocking production releases.
  • Introduce AI-based initiatives to improve developer experience and enterprise workflows.
  • Partner with engineering teams to refine SDK design, user journeys and product mental models.

Presale dashboard in Next.js with Wagmi/Viem and SIWE.
  • Implemented the concierge request lifecycle across mobile, API and three admin interfaces: dynamic form builders, status workflows, agent assignment, invoicing, broadcasts, invitation codes and RBAC.
