A builder and systems engineer working across blockchain, automation, privacy, and real-time applications. I build everything from protocol infrastructure and autonomous agents to full-stack products and developer tools — with an emphasis on clean architecture, verifiable systems, and solving problems from first principles.
Selected Work
Stellalpha
Solana Intent & gRPC Execution Layer
Non-custodial copy execution on Solana that follows trader intent rather than blindly replaying transactions. It combines real-time wallet ingestion, custom Rust parsing, and scoped Anchor vault execution.
Vayyl
Stellar Soroban ZK Confidential Settlement
A confidential settlement layer on Stellar that lets users move value without exposing the underlying transaction history. Built with Groth16 proofs, Poseidon commitments, and Soroban smart contracts on Stellar.

smart-mailto
Zero-Backend Smart Email Dispatcher
A zero-dependency, zero-backend smart email dispatcher for modern web apps. Intelligently routes desktop clicks to Gmail, Outlook, Proton, and Yahoo compose tabs while falling back to native mobile mail sheets and automated clipboard recovery.
TaskMarket402
Autonomous WorkGraph & x402 Payments
An autonomous agent workgraph where specialist agents operate under delegated budgets and pay through x402 micropayments. Built with scoped MetaMask smart-account permissions on Base.
WattWave
IoT Energy Monitoring & Control
A full-stack energy monitoring system combining ESP32 firmware, True RMS measurement, MQTT telemetry and a real-time control dashboard.
ProofDrop
Private Eligibility & Anti-Duplicate Claims
A Stellar Soroban protocol that proves eligibility with zero knowledge while preventing duplicate claims through Poseidon Merkle proofs and on-chain nullifiers.
Additional Tooling & Systems Builds
Automated options trading execution engine with nearest-expiry selection, automated support/resistance triggers, and PostgreSQL logging
Open-source GUI debugger for developers to test 0xGasless smart accounts directly on Avalanche
Automated CLI tool to convert dust to SOL via Jupiter, burn spam tokens, and close empty ATAs to reclaim rent SOL
Browser-based binary utility stripping 131,584-byte bootloader headers from OEM firmware for OpenWRT recovery
Capabilities
Systems & Backend Engineering
Designing stateful services, low-latency pipelines, event-driven systems, and reliable execution infrastructure.
Blockchain & Protocol Engineering
Building smart contracts, execution flows, wallets, and protocol infrastructure across multiple blockchain environments.
Privacy & Security Engineering
Designing systems around cryptographic verification, constrained permissions, trust minimization, and privacy-preserving computation.
Automation & Agent Systems
Building autonomous workflows, delegated execution, agent coordination, and machine-to-machine payment systems.
Full-Stack Product Engineering
Turning complex backend systems into usable products, dashboards, visual tools, and data-heavy interfaces.
Real-Time, IoT & Low-Level Tooling
Working closer to devices and data streams: telemetry, embedded firmware, binary processing, and developer utilities.
Builder Journey
Major build arcs — several projects were developed in parallel.
- TaskMarket402 (May 26 – Jun 8): Engineered autonomous agent workflows integrating machine-to-machine x402 HTTP micropayments with MetaMask ERC-7715/7710 smart account delegation on Base Sepolia.
- ProofDrop (Jun 18 – Jun 25): Built anti-duplicate grant eligibility verification on Stellar Soroban using Poseidon Merkle membership proofs and on-chain nullifiers, deployed to Stellar Testnet.
- Vayyl (Jun 29 – Jul 12): Designed and deployed confidential settlement protocol with 9 Soroban smart contracts, Groth16 zk-SNARK verification over the BN254 curve, and Poseidon2 note hashing to Stellar Testnet.
- Deployed Soroban contracts with verified claim flows on Stellar Testnet, and functional x402 payment verification on Base Sepolia.
