Built agentic workflow systems, product surfaces, and technical execution loops for Sail while coordinating across protocol, infrastructure, and strategy tracks shared across the team.

Building AI-native products, workflow systems, and infrastructure.
I work across product interfaces, backend services, databases, agent tooling, smart contracts, and startup execution. The through-line is turning ambiguous workflows into shipped systems that people can actually use.

Selected work
Roles, startups, and shipped systems.
Operating track record across product engineering, agent workflows, venture-backed software, civic infrastructure, hackathon systems, and identity research.
Built a Launchpad-backed civic governance platform with a bootstrapped team of three. Quae partnered with Stevens Student Government and expanded into Hoboken community work with local organizations and city relationships.
Co-founded a Web3 builder community and shipped ETHGlobal projects under the Cabal Labs umbrella, including Cabal Chat, ETHWaldo, and Tap Contacts, earning five project awards across Istanbul, Paris, and Bogota.
Built a decentralized identity and authorization prototype for application-level trust, access control, and portable user authority at Stevens Institute of Technology, presented as an Ansary finalist project.

Case study
Sail.money: agent workflows, beta traction, and managed-account execution.
One selected story from a broader product engineering track record. Role: co-founder and lead technical developer, with protocol, infrastructure, and strategy tracks shared across the team.
Safe or account holds assets and controls revocation.
Permission signer authorizes a live policy reference.
Route, calldata, value, workflow, return, gas, and fee checks.
Manager or agent acts without taking custody.
Sail Beta
As co-founder and lead technical developer, my Sail work centered on agentic workflow systems, product iteration, implementation coordination, and technical execution. The beta proved demand for self-custodial autonomous financial workflows across swaps, bridges, deposits, redeems, and yield allocation.
- $700M+ autonomous execution volume
- 161,776 on-chain transactions
- $600K+ assets under management
- Self-custodial accounts, session keys, stablecoin automation
New Sail Protocol
The team moved toward non-custodial managed-account infrastructure for DeFi: owners keep custody, managers or agents execute within approved mandates, and runtime checks reject out-of-policy actions before funds move. Protocol, infrastructure, and strategy tasks were shared and delegated across team members.
- Mandates enforced by code
- Owner custody separated from execution authority
- Scoped permissions, revocation, pausing, expiry, and replacement
- Workflow orchestration, SDK surfaces, and evidence reports
Company-level evidence for performance, risk controls, and allocation infrastructure.
