System Design & Architecture Portfolio
Selected architecture, system design, and engineering leadership work spanning enterprise integration, payments, distributed systems, blockchain infrastructure, DeFi protocols, and trading systems.
Salus / Solver: Execution Infrastructure Evolution
Salus is the current system, but the story scans best as Solver -> Salus.

Solver established the original arbitrage and route-execution foundation.
- Tycho-driven route universe, graph updates, simulation, profitability gates.
- Queue-separated hot path and execution queue.
- Low-latency execution infrastructure signal.

Salus evolves the Solver architecture into clearer trading/execution infrastructure.

- Postgres read models, replay validation, route-profit gates.
- Strategy and execution staging separation.
- Migration/refactor maturity signal.
Seamless Protocol



Leverage-token architecture and CoW intent rebalancing contribution track.
- Leverage-token mint/redeem and collateral-ratio controls.
- Rebalance automation, keeper order creation, WIP solver execution.
- Strong DeFi protocol and intent/rebalancing signal.
Eave DeFi Protocol


WIP intent-oriented DeFi protocol architecture.
- Arbiter, Allocator, Solver, hook, flash-router, ERC-7683 roles.
- Hook-triggered execution and solver payload risk.
- Intent execution architecture signal.
Eco


Eco Routes proving architecture contribution track.
- Settlement state, destination world state, and fulfilled-intent proof ladder.
- Solver/filler lifecycle and reward release.
- Cross-chain proving and settlement signal.
EAVE

Substrate/FRAME and parachain architecture track.
- Runtime, node service, pallets, collator lifecycle, relay-chain boundary.
- Project-owned versus upstream framework evidence.
- Blockchain infrastructure breadth signal.
Emasset Prototyping

Payments/API prototype-to-production readiness analysis.
- OpenAPI, protobuf, gRPC, grpc-gateway, generated artifact governance.
- Payments, KYC, fiat rails, ledger, custody, settlement readiness gaps.
- Fintech platform architecture signal.
