I conceptualized and Built Decatron Africa's first end-to-end real estate marketplace that aims to make real estate transactions as seamless as online shopping with features like 1. Automated rental agreement, with E signatures 2. Payment gateway implementation Paystack and Monnify 3. Property, agent and client location tracking with Google Maps and Google Routes API. and used websocket for real-time location update 4. Availability scheduling, and booking system Built an international trade Settlement system that was integrated with the Internet computer Blockchain with the following features 1. A cross-chain wallet, that supports tokens converting BTC, USDC, and ETH to its Internet Computer Protocol equivalent ckBTC, ckUSDC, and ckETH, which allows users to able to use any of these tokens in the ICP ecosystem. 2. On and Offramp capabilities, from crypto to Fiat and vice versa, to achieve this we integrated with payment Flutterwave 3. Automated Promissory note, and invoice generation. 4. Merchant checkout page integration via Iframe (this feature allowed for directly loading the merchant checkout page as an Iframe on how platform) Javascript postmessage API was used for this I am a natural leader. I currently building my startup, but since it's been difficult to raise funding I decided to get a Job for a couple of months, and if I like the job maybe a year to support myself, before going back to building my startup. I conduct user interviews a lot so I do know how to align products with user needs, as you can only really learn this by experience, I think this gives me an edge over the average Software engineer If you are looking for a freak to join your startup, someone who is obsessed with getting things done, who can learn and iterate quickly, who owns the project, who thinks and works like an entrepreneur. then I might be the guy you need.
