Experienced Blockchain Developer and Backend Engineer with 6 years of hands-on experience across EVM, Solana, Tron, and Bitcoin ecosystems. I specialize in building secure, scalable decentralized applications and infrastructure — from smart contracts and cross-chain bridges to blockchain indexers and full-stack backend systems. My core strengths lie in Solidity, Rust, and Node.js, with deep expertise in designing backend APIs, managing cloud infrastructure (AWS), and architecting systems that handle high-volume transactions across networks like Ethereum, Binance Smart Chain, and Polygon. I’ve delivered DeFi platforms, crypto wallets, NFT systems, and blockchain data pipelines, while also mentoring developers and leading technical decisions as a tech lead. I enjoy solving complex problems and driving innovation in blockchain products from the ground up. I'm currently focused on roles involving blockchain development, backend engineering, and infrastructure — especially those that span multiple networks and require performance, security, and scale.

Experience
Blockchain Developer
Bee One Innovations 2023 - 2025
Designed, developed, and audited smart contracts for DeFi applications across Ethereum, Binance Smart Chain, Polygon, Tron, and Solana. Audited 25+ smart contracts using Slither, Mythril, and manual review — identifying and mitigating critical vulnerabilities before deployment. Built a secure and scalable cross-chain bridge (DBridge) that processed over 26,000 transactions, handling an average of 100 daily cross-chain token transfers. Architected and developed high-performance blockchain indexers for Bitcoin and Dogecoin, enabling wallet and transaction data retrieval. Optimized API performance to support 150+ concurrent users with multiple wallets, maintaining a response time under 3 seconds. Leveraged Rust and Solana's development toolchain to implement performance on-chain logic. Provided ongoing technical support and training to junior blockchain developers; improved team delivery velocity through better tooling and code standards. Created internal documentation and best practices to enhance team consistency and raise security awareness.
