With a background in Electrical and Electronics engineering, I have worked in fast paced startups over the last 6 years to build and scale applications that are not only purposeful and maintainable but also evolve to leverage new tech and trends. Recently, I worked to architect and implement two mobile app applications and web apps all powered with Rails and integrating AI in search, recommendation and extraction areas. This has helped them get to a level of personalization that beats competitors and increased our retention rates by over 30%. Whether you are seeking a team lead, CTO, or a driven and adaptable backend or frontend engineer to join your team, I am a highly capable and experienced professional ready to make a lasting impact.

Having worked with various platforms including AWS, GCP, HuggingFace and more, I am always willing to learn and keep chipping at hard problems and leveraging what exists to build solve business and engineering problems. I look forward to chatting about your busines and how my skills and expertise can be of value to your team, clients and business objectives.
