Portfolio

Farm-to-Us

● Developed a quote-matching system using Node.js, PostgreSQL, and Django, Golang event and security listeners meant to triple contract closure rates across the platform. ● Architected NFT-backed lending engine with Chainlink and React, that enables risk-adjusted credit access with zero defaults. ● Built DAO and escrow smart contracts using Solana and Rust to govern agri-economic decisions, reducing disputes by over 80%. ● Integrated LLaMA-2-based AI agents using LangChain and Supabase to reduce support workload by 70% and boost user engagement. ● Architected multi-token smart contracts in Solana and Rust to deliver a 2x yield improvement on tokenized farming assets.

Jamii’s Giving

● Developed a decentralized donation platform using Solidity and IPFS, reducing fund-matching delays by 10x. ● Built milestone-based smart contracts with Web3.js for automated fund releases, increasing donor retention by 30%. ● Designed real-time donor dashboards using React and Supabase to enhance transparency and impact visibility. ● Automated deployments with Docker and GitHub Actions to reduce time-to-launch and eliminate manual setup errors. ● Implemented i18n in Next.js to support multiple languages and expand accessibility to users in 4+ regions.

ApexNest Holdings

● Developed machine learning credit risk models using Python, Flask, and Node.js, increasing default prediction accuracy by 25% across multi-asset portfolios. ● Built performance dashboards for investment teams using React, Next.js, and AWS, reducing reporting cycles by 40% and improving decision-making. ● Designed and deployed pricing models for fixed-income assets using QuantLib and NumPy, enabling consistent and transparent valuations. ● Implemented trading strategy pipelines powered by WebSocket APIs and Solana, optimizing execution in response to live market data. ● Led collaborative projects across 3-tier architecture systems, integrating frontend dashboards, backend APIs, and Ethereum smart contract logic to drive a 29.5% improvement in investment ROI.
