Abhishek Kumat
@abhishekkumat
Lead backend engineer specializing in Ruby on Rails, APIs, and AWS.
What I'm looking for
I’m a Lead Software Engineer focused on backend systems, designing and delivering scalable, high-traffic applications primarily with Ruby on Rails. I bring 6.6 years of experience building production features and contributing full-stack work using React and Angular.
In my recent roles, I’ve led engineering delivery for customer experience platforms—covering membership, rewards, gifting, and discount validation. I architect and implement RESTful APIs and microservices-style systems with an emphasis on performance, reliability, and clean system design.
I’ve worked deeply with third-party integrations including Paytronix, Stripe, and Twilio, and I’m comfortable building secure payment and rewards workflows. On the delivery side, I follow CI/CD practices, deployment automation, and quality-focused development approaches (including TDD/BDD, code review, and Agile/Scrum).
What I value most is mentoring and driving projects from design through production. Across client and team environments, I’ve consistently improved operational efficiency, reduced manual effort, and helped teams raise standards for API reliability and front-end/backend collaboration.
