Architected and built a production-grade custodial blockchain wallet infrastructure, scaling from 9,000 to 2+ million unique wallets on AssetHub while maintaining enterprise-level security and cost efficiency.
Key Achievements: • Reduced infrastructure costs by 99.97% ($600/month vs $2M/month) with custom secret storage vs HSM-based solutions, saving $24M annually • Onboarded 2+ million wallets on Polkadot's AssetHub (from 9k to 2M+ unique wallets) • Built 7 production/staging APIs across GCP and AWS (Terraform, APIs, databases, DevOps)
High-Performance Cryptography: • Engineered Rust/Rayon data-parallel pipeline achieving 10,000+ wallets/minute with CPU-intensive XSalsa20Poly1305 encryption • Optimized parallel batch processing and memory management for massive concurrent workloads
Security Architecture: • Shamir's Secret Sharing (5 parts, threshold 3) - secrets never stored in single location, distributed across multi-region isolated services • Multi-layer encryption (XSalsa20Poly1305, KMS keys, database encryption, VPC isolation) with double encryption at custodian level • Distributed secret reconstruction API for on-demand transaction signing
Fault Tolerance: • Multi-region, multi-cloud (GCP + AWS) - operational even if 2 of 5 custodians fail • VPC-protected services, JWT auth, IP whitelisting, WAF, zero-downtime deployments
Tech Stack: Rust (Rayon, XSalsa20Poly1305), NodeJS, TypeScript, Terraform, PostgreSQL, Docker, Cloud Run, ECS, Polkadot/Substrate, sr25519

MODA is a platform for minting, collecting, socializing, and earning rewards in the Web3 electronic music space.
Led a team to develop and deploy smart contracts, including tokens, NFTs, staking platforms, and abstract accounts (ERC-4337) in Solidity.
Built full-stack systems with React and TypeScript, Node APIs, and digital fingerprint collectibles for renowned artists such as deadmau5, Kaskade, Nero, and Noizu.
Successfully launched a staking contract in 2023 and released numerous NFTs.
ink! is the smart contract programming language for Polkadot.
Joined a fully remote team to build and maintain the ink! programming language in Rust.
Contributed to developer tutorials and documentation, enhancing the overall developer experience.
Created a low-level JavaScript client library, useink, which featured a simple API (similar to Wagmi and Viem) to streamline frontend development for ink! contracts and Polkadot blockchains.
Developed features including browser wallet connection management, error handling, JS-to-bytes data type mapping, data parity between new block changes on the blockchain, and contract on-chain deployment from the browser.
Implemented a light client feature using smoldot, enabling trustless browser connections to other nodes without relying on centralized third-party blockchain gateways.
Built numerous full-stack dApps using Rust and useink.

Solvana is an innovative all-digital platform revolutionizing the solar purchasing experience by eliminating salespeople. It offers comprehensive tools for solar experts to design and propose options, and allows customers to customize their systems with real-time incentive calculations and financing options.
Led a small team in building a robust tech stack with an event-driven architecture, guided by Domain-Driven Design (DDD) principles, derived from intensive planning sessions (Event Storming) with stakeholders.
Developed and deployed NodeJS APIs, React front-ends, micro lambdas for asynchronous features, and used Terraform to manage Dockerized containers in AWS Fargate.
Collaborated closely with stakeholders throughout the product development lifecycle.
Achieved $1 million in gross revenue within the first year of launch.
The Paraverse
PIPS is an innovative on-chain generative NFT project that has produced over 250,000 unique playing cards across thousands of multi-asset-owned NFTs (playing card decks). Each deck's DNA was fairly generated on-chain and rendered off-chain using a custom engine that compiles hand-drawn elements into a single image, resulting in NFTs with over 600 rarity traits per deck.
Solved the challenge of on-chain randomization without relying on oracles, avoiding the complexity and dependency on secondary tokens like Chainlink's LINK. This solution was very difficult to be gamed. The solution involved a delayed reveal mechanism.
Developed a sophisticated on-chain and off-chain integration to ensure seamless DNA generation and rendering.
