Introduced new features/improvements for both the www.5miles.com Webapp and its Progressive Web App (PWA) platforms built with Angular and Sails.js: listings, reviews + ratings, product categorization & tagging, search auto completion, and many more

Designed and created the CyberMiles Explorer Webapp with Vue & Vuex + Egg.js, fetched and dissected blocks & transactions from our Mainnet (www.cmttracking.io) & TestNet (testnet.cmttracking.io) through Web3-cmt.js, and displayed every aspect of our CyberMiles DPOS model to CMT stakeholders

Enforced SEO for www.cybermiles.io in September, resulting in reduction of site load speed by over 2 seconds, and increases in users (+67%), organic traffic (+94%), and click through rate (+20%) before the MainNet launched in October

Migrated cybermiles.io from WordPress to a JAMstack architecture with Gatsby.js (React + GraphQL), Contentful (Headless CMS) and Netlify (Host) to increase speed, security and scalability

Leveraged the speed and flexibility of Hugo to generate multiple fully customized websites (www.litylang.org & www.noomiwallet.com) for clients with tight deadlines
