Contributed to the design and development of decentralized AI infrastructure at an a16z/Coinbase-backed startup ($8.5M seed). Led engineering efforts across TEE-based compute (AWS Nitro Enclaves), verifiable inference systems, and LLM deployment pipelines. Delivered three core platform products from design to production. Key products delivered: • MemSync — private LLM-powered memory extraction and digital twin platform • BitQuant — Bittensor subnet validator/miner with dynamic question generation and anti-gaming security Tech stack: Go · Python · Cosmos SDK · LLM/RAG · TEE (AWS Nitro Enclaves) · RBAC . Datadog, Kubernetes, Docker

Providing blockchain architecture design and implementation guidance for clients on the Hedera platform. Worked closely with clients to design, validate, and implement blockchain solutions using the Hedera Hashgraph system. Assisted in the architecture design and ensured that all technical solutions adhered to best practices for scalability and security.

Contributed to the design and development of the Qredo Protocol — a decentralized MPC custody and settlement platform (Cosmos SDK / Tendermint) that reached billions in AUM (per company communications), with $97M raised at a $460M valuation. Led a team of 5 engineers. Key contributions included multi-chain integrations (Cardano, Sui, Arbitrum), validator reward mechanism design, L1 node deployment, and transition to microservices architecture. Tech: Go · Cosmos SDK · Tendermint · Solidity · Grafana · Prometheus · GitHub Actions Kubernetes, Docker

As a Blockchain architect at SystemX, I played a role in designing and implementing innovative MVP for integrating blockchain into client solutions. This hands-on experience deepened my understanding of blockchain technology, its challenges, and limitations. Moreover, it afforded me the opportunity to delve into various blockchain technologies, including Hyperledger Fabric, Indy, Ethereum, and more.
