    I have worked as both a Software Engineer and Business Analyst (requirements elicitation and documentation), on various projects, for over 9 years. Most of my work have been within the financial services domain. I have worked on web payment gateway integrations, business automation solutions, banking applications and more. I love to take on challenging projects. Good software, to me, can only be built by working from a user's perspective and maintaining strict compliance to software development best practices. Today, i mostly design and develop Web applications and business automation platforms (including backend services and APIs) using Microsoft .NET frameworks (like MVC, ASP.NET, Entity Framework etc) and Node.js; "Permissioned" blockchain networks/applications on Hyperledger Fabric, using Node.js and Golang; As well as Sentiment analysis, prediction and image classification solutions using Keras on Tensorflow.
