Remote | Jan 2026 – Present

• Built high-throughput backend services in Go for ingestion, batching, compression, and durable storage of large-scale event/log data
• Architected a hybrid on-chain/off-chain architecture storing verifiable references on blockchain while persisting bulk data in decentralized object storage to reduce costs and improve scalability.
• Implemented peer-to-peer networking features including NAT traversal and direct node-to-node communication without centralized servers using libp2p
• Developed indexed query engine with selective retrieval and progressive streaming, enabling efficient search across large immutable datasets
• Technologies: Go, Python, Solidity, PostgreSQL, libp2p, Foundry, Decentralized Storage
• PR1, PR2

Remote | Sept 2025 – Present

• Built a quantum-resistant identity system using ML-DSA (CRYSTALS-Dilithium) with a Rust–Node.js hybrid backend cryptographic core, enabling sub-50ms deterministic W3ID generation.
• Designed a bias-free 12-digit ID derivation pipeline using SHAKE256 entropy, keyed BLAKE3 hashing, and 48-bit rejection sampling, ensuring uniform distribution and zero collisions at scale.
• Implemented a 2-of-3 MPC non-custodial smart wallet infrastructure via Openfort SDK with encrypted recovery sessions and no single point of failure.
• Built a multi-tenant developer SDK platform with OAuth-style auth, AES-256-GCM encrypted API keys, secure webhooks, and hardened rate-limited REST APIs.
• Technologies: NodeJs, Typescript, Rust, PostgreSQL, Cryptography

• Technologies: Solidity, Foundry, ERC-8004, EVM

• Building production grade and scalable backend infrastructure in Go, NodeJs+Ts
• Studying and Contributing some of DeFi protocols

Before starting the walkthrough, here is a quick summary of what this prototype demonstrates.

This prototype implements a simple end-to-end consent workflow to validate the core idea behind the project: secure, user-controlled data access in IoT care systems. In this setup, a caregiver can request access to a patient’s data, the patient can either approve or deny that request, and any participant can later verify the final access status.

Each step updates the system state and is recorded so that the decision process remains transparent and traceable. This mirrors the governance and audit trail that the full project aims to provide.

The goal of this prototype is to prove that the basic workflow works reliably, forming the foundation for extending the system later with more advanced governance rules, compliance checks, and multi-party oversight.
