## Professional experience

### Kambria — KAT Tokenomics

Backend Developer, System Prototyping DAO. May 2026–Present. Remote.

Backend engineering for the Credit → Karma → KAT tokenomics pipeline on a multi-tenant DAO platform. Work includes an immutable Credit ledger with period-cap enforcement, a three-tier KAT settlement cap cascade, and an OpenAI GPT-4o-mini-backed weekly reporting pipeline.

Technologies: NestJS, Node.js, MySQL, JWT/bcrypt role-based access control, OpenAI GPT-4o-mini, DAO tokenomics.

### Digital South Trust

Software Engineer Intern — Emerging Technologies. March–July 2026. Remote.

Architected a multi-tenant Certificate SaaS and a Polygon certificate issuance pipeline. Certificate hashes are anchored on-chain through a Solidity smart contract on the Amoy testnet, with idempotent retry and public on-chain verification.

Technologies: Next.js, MongoDB Atlas, Stripe, Razorpay, Polygon Amoy, ethers.js, Solidity.

### Lokachakra

Software Engineer Intern — Backend & Cryptography, Lokachakra, a UK-based startup. June–August 2025. Remote.

Built a Rust backend for zero-knowledge identity and KYC using Circom and Groth16. The portfolio reports support for 10K+ users and an 85% reduction in verification time. Engineered a cryptographically secure wallet system with reported throughput of 5,000+ TPS at sub-15ms latency.

Technologies: Rust, Circom, Groth16, zero-knowledge proofs, KYC, high-throughput wallet systems.

## Research

### Post-Quantum Cryptography Research Initiative

Software Engineer Intern — Cryptography Research. January–May 2025. Remote.

Benchmarked four NIST post-quantum cryptography finalist schemes against RSA/ECC. Proposed hybrid migration strategies with a reported 35% lower overhead for transitioning production cryptographic systems.

Topics: post-quantum cryptography, NIST PQC finalists, ML-KEM, RSA/ECC, hybrid migration.

## Selected projects

### Decomm — Quantum-Resistant P2P Infrastructure

AlterBlock project. 2025–2026. Open source.

A sovereign P2P node using a two-phase ML-KEM-1024 post-quantum key encapsulation handshake to establish per-session AES-256-GCM channels. RISC Zero zkVM proves ZK Merkle membership against a Solana-anchored root. The portfolio reports that a security audit surfaced and patched two critical verifier-bypass vulnerabilities.

Technologies: Rust, libp2p Gossipsub, ML-KEM-1024, RISC Zero zkVM, AES-256-GCM, Solana.

### TRIAD — AI Market Microstructure Engine

Independent project. 2025–2026.

An event-driven system ingesting live Binance L2 order-book depth and computing VPIN, spoofing, and order-imbalance signals with a SHA-256 commitment hash chain. ONNX inference combines with per-regime HNSW episodic k-NN memory for reported sub-10ms decisions.

Technologies: Rust, Python, NATS JetStream, ONNX Runtime, PostgreSQL, pgvector, HNSW.

### ZK Proof-of-Reserves Vault — ERC-4626 Yield

Open-source project. 2024–2025. Sepolia testnet.

A full-stack ZK-verifiable ERC-4626 yield vault with an off-chain Groth16 Proof-of-Reserves pipeline and an auto-generated Solidity verifier. Five contracts are reported as deployed and Etherscan-verified on Sepolia. These are testnet deployments.

Technologies: Solidity, Foundry, Circom, Groth16, Aave V3, Next.js, Sepolia.

## Education, publication, and honors
