Software Engineer
Hi there, I'm Paul. I live in New Jersey. I’ve been a developer for 9 years now. I came to software development because I love to create things. I love it when people use those things, and I love it when those things help people. I come from a creative writing background which is very different from software development but there is a lot of similarities between a well crafted piece of writing and a well crafted bit of code. Since I began coding, I’ve built digital museums, multi-device shopping experiences, commuter facing kiosks, and mall directories. I want to keep on building really cool and useful things, share my knowledge with others. I'm well versed in Javascript, Typescript, React, Redux and associated Front End technologies. I can't wait to help you out.

Thrived in start-up environments and teams that do battle daily for product and customer success. I have successfully designed and built systems in various landscapes, industries, and infrastructures.
”Building a sustainable business process is not about products, services or viability alone, at core it is about what value you choose to give to your customers, value that is perceived by your customers not just a percept imagined by business owners.” An ICT professional with 1.5 decades of industry experience which includes about 7 years of lead/managerial roles and responsibilities. INTP by personality type that is reason why I love being drawn into problem solving activities, analytical related tasks and come up with efficient and feasible outcomes. Experienced in different industries (domains such as Telecom, E-commerce and finance).

Different roles like analyst, programmer, database developer, front end engineer, architect, project manger at various projects have helped me acquire omni directional experience. And I’d love to impart or contribute further and continue to gain forward. Beyond work sphere, I love to live the spirit of Indian classical music, but in general I adore all forms and genres of music and sound that can be brewed by humans, or any other species of this planet. I’ve been self teaching Indian bamboo flute. And love to try other instruments too like piano. If you find me worth connecting, sharing or collaborating, feel free to message me.
