Leading the development of backend systems for RPG studio games at Joyride that leverage the dynamic Play-to-Earn model. Currently, I’m at the helm of the development of ”Tennis Champs,” an innovative game interwoven with the Flow blockchain ecosystem. I’ve driven the architectural design for features such as the marketplace, champ gears, recruit passes, and seasonal shop. Strategically enhanced development lifecycle processes to consistently deliver high-quality features seamlessly and on schedule. The game features seamlessly tradable NFTs on the Opensea marketplace.

Spearheaded the development of ”Vormir,” an internal service designed to manage the lifecycle of cohorts (creation, access, deletion) and to serve cohorts to other nferX services or apps on demand. The application was written in Golang and involved close collaboration with clients and other stakeholders. We implemented a finite state machine (FSM) to manage multiple states within the application. Effectively addressed connection losses with Kafka broker using Goroutine channels, ensuring uninterrupted data flow. The tech stack included Python for scripting, MongoDB as the backend storage, Redis for caching, and RabbitMQ and Kafka for message queues for inter-service communication. In addition, Google Cloud Bucket and MinIO were used as disaster-proof persistence storage. Contributed to ”Clinical Trials, Rapid2x” by designing and developing several APIs in Golang. Additionally, I played a significant role in the ”Sleepyhead” project, contributing to high-level and low-level designs for some of its features.

Steered the migration of the ”Cell Lines Explorer” application from Python to Golang, implementing extensive optimizations that yielded a remarkable 10x boost in the performance of critical APIs. This application empowers users to discern the enriched features within test group cell lines when compared to a control group. Designed and developed the ”Disease Prevalence” application from scratch, processing publicly available structured/unstructured data and creating ranking algorithms to fetch the most relevant documents and extract relevant sentences. The tech stack included Golang and MongoDB.

Built the backend system for the online mobile game ”MGoT” using Golang, PostgreSQL, and Redis. Leveraged AWS cloud EC2 and RDS for server hosting. Developed a common microservice for in-app purchase/subscription verifications at App/Play Stores for mobile games using Golang. Leveraged AWS Lambda for hosting the corresponding APIs. Created a routing service for collecting, modifying, and sending event data from games to a third-party analytics service provider called Amplitude using JavaScript on Node.js. Developed a Facebook messaging service that sends specific messages to targeted players based on a retention algorithm. Also leveraged Embed.js framework for creating web hooks to receive Facebook events. Merged player profiles playing on different realms into a single player for the game ”TGF” using a Ruby script. The game was developed in Rails, RSpec, MySQL and Redis. Migrated players for ”TGF” from the Wonderhill platform to Facebook using a Ruby script. Built various features into ”TGF,” including the Token Store and Limited Time Missions. Helped contain a product design issue related to nested chest box opening in the game ”DoA” by converting the corresponding synchronous API to an async model. Served as the single point of contact for engineering requirements of Business Intelligence and Xpromo for Kiwi games post-acquisition by RockYou. Integrated RockYou Analytics into the Kiwi Games during the migration. Technologies include Java, Ruby, PHP, and Scribe.
