Built a real-time arbitrage searcher that detects and executes 2-leg and triangular arbitrage cycles across 7 Solana DEXes (Raydium, Orca Whirlpool, Meteora DLMM, Pump.fun) using a unified trait-based abstraction layer. Designed low-latency streaming architecture using Yellowstone Geyser gRPC for real-time pool state updates, replacing traditional RPC polling to minimize detection-to-execution time. Integrated Jito block engine for MEV-protected transaction bundling with dynamic tip calculation based on profit margins and landing probability percentiles. Developed graph-based cycle detection using sparse adjacency matrices to efficiently enumerate profitable trading paths across fragmented liquidity pools. Built companion Rust smart contract (Anchor) for atomic multi-DEX swap execution with account lookup table optimization to reduce transaction size.

Telegram bot that scans Solana token contracts to detect developer dumping behavior and expose red flags (dev supply concentration, sell activity, LP status, market cap, liquidity) for meme coin traders, using TypeScript, Solana Web3/RPC APIs, DexScreener integration, and the Telegram Bot API. Designed and implemented a bubblemaps-style analytics layer using D3.js to visualize wallet connections and token distribution, helping users quickly identify clustered or suspicious ownership patterns on Solana. Developed a Next.js frontend and a NestJS backend API powered by Postgres, Drizzle ORM, and Redis caching to ingest on-chain data, build wallet-relationship graphs, and serve interactive bubble maps alongside bot’s risk metrics for each token.

Worked on the development of the GoWish API using NestJS, GraphQL Federation, and Neo4j, enabling robust data interaction and manipulation. Developed a comprehensive Next.js based Admin Panel, providing super control to administrators for efficient management. Implemented an Advertiser Panel serving as a SaaS solution for collaborating advertisers, fostering business partnerships and revenue growth. Constructed a Statistics API with NestJS and SingleStore, facilitating efficient storage and retrieval of all statistics for analytical purposes. Contributed to the creation of our proprietary OAuth 2.0 service, enhancing security and streamlining authentication across our platforms.
