Multi-chain e-sports platform — casual and competitive gaming across EVM and Solana.

• Inherited a fragmented 5-engineer team with no shared coding standards and an unstable wallet layer across three chains. Defined coding standards, redesigned the multi-chain wallet architecture, and introduced a staged rollout process — cutting bug rates by 22% and pushing feature delivery up 28%.
• With connection failure rates hurting user retention across EVM and Solana, architected a unified multi-chain wallet infrastructure using Wagmi, Viem, Sequence, and Dynamic — reducing connection failures by 35% and meaningfully improving session completion.
• Onboarding drop-off was high due to a slow, multi-step wallet deployment flow. Streamlined the CI/CD wallet deployment pipeline, increasing new-user onboarding speed by 20%.
• Authentication errors were causing a measurable dip in user retention. Integrated SIWE with Next Auth to deliver seamless wallet-based login — cutting auth time by 350ms, improving retention by 15%, and nearly eliminating login errors platform-wide.
• A 40k+ LOC React codebase with no clear ownership was shipping slow and breaking in production. Led a full modernization initiative — reducing page load times by 25%, cutting production errors by 40%, and enabling faster, safer feature experimentation.
• To support duels and tournaments, the platform needed on-chain settlement without a centralized custody risk. Integrated an Anchor-based Solana program handling account validation, PDA derivation, and CPI calls to the SPL token program — enabling fully trustless tournament payouts.

Web3 consultancy delivering decentralized applications and blockchain solutions for external clients.

• Led a distributed team of 8 across multiple client dApps with no consistent integration patterns, each project reinventing the wheel. Set the technical roadmap and standardized cross-chain integration patterns reused across 4 client client dApps, and chose IPFS over centralized storage to eliminate single-point-of-failure risk for NFT metadata at scale.
• Tasked with launching an NFT marketplace on Canto — a chain with under 50k active wallets and no existing marketplace ecosystem. Architected the platform from a cold-start MVP, reaching $10k+ in NFT volume within 6 weeks of launch despite the constrained addressable market.
• NFT metadata latency was degrading listing UX at scale. Architected the data layer on IPFS/Pinata, enabling 1k+ live listings and reducing metadata load times by 13%.
• Clients needed real-time trading visibility to compete with centralized platforms. Delivered real-time trading and analytics dashboards using Web Sockets and The Graph — supporting 10k+ trades/day with sub-second data freshness.

AI-powered platform transforming user images into creative digital artworks.

• With the platform scaling rapidly toward 100k MAU, the existing REST data layer was bottlenecking API performance and causing session drop-off. Rebuilt the data layer with Apollo Graph QL — cutting API response times by 40% and lifting session depth by 20%, supporting continued growth without infrastructure scaling costs.

Early-stage Web3 analytics startup — real-time on-chain dashboards for DeFi traders.

• The startup's analytics dashboards were polling-based, producing stale data and losing DeFi users who needed sub-second trade visibility. Designed and built a low-latency event-driven data infrastructure — cutting update lag by 50% and enabling real-time on-chain signal delivery to dashboards.
• With 2k+ active users and no reliability guarantees, the monolithic deployment was a single point of failure. Architected and deployed containerized microservices on AWS (Dynamo DB, EC2, Cloud Watch, S3, Lambda, IAM, Amplify, Cloud Formation) using Node. js, Postgre SQL, Redis, Docker, and Git Hub Actions CI/CD — achieving 99.9% uptime and laying the foundation for horizontal scale.
