I am a full-stack developer with a decade of experience. Among software domains, my focus has recently been in delivering full-stack web-based solutions on desktop and mobile, and API solutions. I have also developed mobile and desktop applications. Among programming languages, I am proficient in ReScript, ReasonML, TypeScript, and JavaScript.I am also very willing to work in Scala. Among technologies and frameworks, I am proficient in React.js for frontend development; Node.js and Fastify for API development; Jotai, RxJS for state and event management. I have also implemented and deployed applications based on the Elm Architecture. Among business domains, I have gained experience in IoT, travel and booking management, automation, weather index insurance, and quality-of-life improvement utilities. Among soft and social skills, I emphasise on my accountability, transparency, my ability to learn new stuff quickly, and my communication skills. Reviews from my clients below are testimonies to those aspects. Another important skill is to gain understanding of a project and gathering its requirements. I have been writing software since 2011. This experience has taught me that software development is about tailoring a solution to fit the problem at hand more than about a programming language or a framework. At the core of this process lies gathering requirements and use cases; followed by software design and architecture; aided by testing, concise documentation as well as clear communication.
