Built and maintain DEXArea, a production Solana Web3 platform providing token, DeFi, and blockchain management tools. My work covers the full product lifecycle, including architecture, frontend and backend development, wallet and blockchain integrations, transaction workflows, APIs, deployment, monitoring, and production maintenance. The platform includes Solana token creation and management, SPL Token and Token-2022 workflows, mint/burn operations, metadata management, authority controls, multi-sender tools, liquidity and Raydium integrations, and other Web3 utilities. Tech: Solana, TypeScript, Node.js, NestJS, React/Next.js, RPC APIs, Raydium, SPL Token, Token-2022, IPFS, Linux and Nginx.

Built SPLKit as a production Web3 toolkit for Solana token and blockchain workflows. The project combines user-facing Web3 tools with blockchain transaction infrastructure and backend APIs. My work includes product architecture, frontend/backend development, wallet connectivity, Solana RPC integration, token operations, transaction construction, error handling, deployment, and production support. The project demonstrates my ability to build complete Solana applications rather than isolated scripts or smart contract integrations. Tech includes Solana, TypeScript, Node.js, Web3, SPL Token, RPC infrastructure, wallet integrations, REST APIs, Linux and production deployment.

Designed and built Pinr, a production-grade IPFS metadata and content infrastructure service for Web3 applications. The system includes API-based uploads, IPFS pinning, metadata delivery, content lifecycle management, backups, monitoring, quotas, authentication, cleanup workflows, and production hardening. I handled the architecture, backend implementation, IPFS/Kubo integration, API design, database layer, Linux deployment, Nginx, security hardening, monitoring, backup workflows, and production troubleshooting. Tech: Node.js, NestJS, IPFS/Kubo, SQLite, REST APIs, Linux, Nginx, systemd, Prometheus, Loki and production monitoring.

Built and maintain DXRA Core API, a production backend platform powering Solana Web3 applications and transaction workflows. The system provides APIs for building and managing Solana transactions, token operations, blockchain integrations, metadata workflows, RPC communication, transaction confirmation, and production error handling. My work includes backend architecture, TypeScript/Node.js/NestJS development, Solana transaction construction, SPL Token and Token-2022 workflows, external protocol integrations, secure API design, IPFS/Pinr integration, monitoring, debugging, and Linux production deployment. The project is designed for reliable production use with clear separation between transaction building, user signing, blockchain submission, metadata infrastructure, and backend services.
