Background
Chief Technology Officer at OVAAL. Architecting the production ERC-4337 SDK, compliance execution path, and multi-rail orchestration that lets licensed EU and MENA fintechs ship crypto features in 4 to 8 weeks. Background spans backend systems engineering, Web3 protocol work, and fintech compliance integration.
What the CTO writes about
- Architecture decisions. Non-custodial-by-default, one SDK surface, versioning as contract, compliance inline in the execution path. Why these choices make the integration timeline real.
- ERC-4337 in production. Passkey onboarding, session-key scoping, paymaster policy, recovery flows that actually work for compliance review.
- Trade-offs. What the architecture gives up. When partners should pick a specialist instead.
