Web Developer (Fe Heavy)

I'm a senior full-stack developer (since 2016), blending frontend firepower with Web3 precision. My core stack is React, Next.js, TypeScript, Node.js, and Solana integrations. I’ve built everything from crypto trading tools and financial dashboards to PWAs, mobile hybrid apps, and custom CMS systems.

I’m currently deep in Web3—building decentralized tools, crypto-native interfaces, and integrating protocols like Jupiter (Solana), AT Protocol (Bluesky), and Capacitor-powered mobile setups. I move fast and ship clean—no fluff, just battle-tested code and real UX.

💡 Past work highlights:
• Built a custom Bluesky client for the crypto community—live swap, token lookup, and DEX integrations
• Integrated React Query, caching, and custom backends for real-time data
• Migrated and optimized legacy apps into high-performance PWAs and cross-platform mobile apps
• Developed a high-efficiency multiparty upload widget that handles large files in parallel chunks with retry logic
• Delivered apps used by NBA teams and museums across the USA, merging solid engineering with high-end design and stability

🛠️ I'm not just about code—I think in product. I bring startup speed, technical depth, and a real obsession with building tools that people actually use. Whether it’s automating crypto workflows, building dashboards, or crafting MVPs that actually ship, I’m in.

Looking for teams building real things in Web3—DEXs, tooling, DePIN, NFT infra, AI + on-chain, or anything bold and technical. I’m open to freelance, full-time, or high-impact collaborations.
