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 NextAuth 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 WebSockets 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 GraphQL — 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 (DynamoDB, EC2, CloudWatch, S3, Lambda, IAM, Amplify, CloudFormation) using Node.js, PostgreSQL, Redis, Docker, and GitHub Actions CI/CD — achieving 99.9% uptime and laying the foundation for horizontal scale.
