• Domain owner of KOHO's subscription plans. Worked with a cross-functional team in transitioning KOHO's subscription model from a freemium structure to a more sophisticated tier-based system. Developed a new Tiers domain service to handle subscriptions, billing, and downstream benefits. This intricately designed system operates as the central hub for all KOHO products delivered through the tiered approach, boasting a robust, event-driven architecture.
• Collaborated with a cross-functional team in creating a vendor-agnostic KYC challenge model that allowed the decoupling of the user onboarding flow and the user KYC flow, hence allowing users to sign-up in lesser steps. Creating this model required migrating the legacy KYC system as an independent domain service, offering a RESTful API and eventing system leveraging AmazonMQ.
• Authored and implemented an RFC that outlined the optionality of ordering a physical credit card during sign-up. This project was instrumental in changing the legacy user onboarding and account creation flows, where a physical card was offered by default, resulting in reducing CAC and user drop-off rates while providing more flexibility and choice to users, and while eliminating tech debt in the legacy system.
• Typical day-to-day included; system-architecture, development, testing, maintenance, and monitoring of GoLang repositories, processes, and deployment infrastructure while working closely with the product and data teams. I also perform PR and RFC reviews, bug-fixing and reconciliation, on-call rotation, and support team members on technical challenges.

• Led an effort to migrate Playo’s legacy monolithic backend to create 7 RESTful CRUD microservices written in Node.js and Python/Django stacks with MySQL and MongoDB as the data stores. These services were, deployed on GCP Infrastructure via bitbucket pipelines.
• Mentored a team of 2 junior devs in developing and maintaining a B2B SaaS application as a website dashboard and PWA written in React.js/Redux, supported by a RESTful microservice backend. This application is used by over 3000 sports venues across India, UAE, Qatar, and Australia.
• Implemented a PWA version of the Playo App's booking flow using React.js/Redux and service workers to facilitate integration on digital storefronts like - Google Pay Spot, PhonePe Switch, and Paytm Mini Apps.

• Received training in building RESTful API systems in Node.js and Python/Django and frontend systems in React.js/Redux leveraging agile methodologies and version control.
• Secured deployment at Playo as a Full-Stack Engineer, on contract.
