- Designing and architecting end-to-end solutions for complex systems, ensuring alignment with business goals and technical requirements.- Transforming, improving and optimizing current systems such as interservice communication through message brokers.- Spearheaded the implementation of an internal analytical system that orchestrates various ETL (Extract, Transform, Load) jobs to gather and consolidate system data such as orders, merchants, payments, and configurations for analytics purposes. Leveraging Metabase, this system provides comprehensive insights to stakeholders, enabling data-driven decision-making and business optimization.- Overseeing the implementation and deployment of the system, working closely with different teams to ensure successful delivery.- Regularly review solution architectures to identify areas for improvement and address any issues or challenges. Currently, I'm conducting performance reviews of our systems to optimize resource usage and improve overall efficiency.- Implemented a local Kubernetes cluster for rapid development, ensuring developers have a fast and efficient environment to build and test microservices-based applications. This initiative significantly reduced development time and improved overall productivity within the team.

- Design and develop Event Driven Architecture(EDA) with Microservices and Apache Kafka.- Wrote Analytics SDK Producer a real-time data ingestion pipeline using Apache Kafka that scales to 1,000,000s of messages per second.- Builds RESTful and GraphQL APIs on a NodeJS to be used by a React-based front end application.- Build JSON DSL for audience filters.- Impelemented Push Notification service with backoff strategy.- Implemented RabbitMQ for distributed tasks and IPC between services.- Implement schema migrations for multiple clients for SaSS based enterprise application.- Initiate and Implement application CI/CD through Travis CI and Github.- Conversion of legacy ES5 codebase to ES8.- Participate in peer-reviews of solution designs and related code

- Designed and implemented NodeJS APIs, micro services, caching layers, and monitoring.- Manage environments with Digital Ocean and expand with horizontal scaling.- Designed horizontal scaled architecture for NodeJS applications.- Implemented Docker for backend infrastructure.- Developed backend HTTP RESTful Web API with NodeJS, MySQL and MongoDB.- Implemented Elasticsearch Stack (ELK) for application logs and error logging.- Implemented RabbitMQ for distributed tasks and IPC between services.- Single Page App (SPA) front-end programming Angular and Material Design.- Implemented Test framework MochaJS for NodeJS Applications.- Integrated NewRelic in backend application for performance and monitoring.- Manage code reviews for optimizations.- Implemented front-end instrumentation with Google Analytics.- Develop and direct software system testing and validation procedures, programming, and documentation.

- Migrated to NodeJS architecture from PHP.- Design, Develop and Publish iOS and Android App using Ionic Framework.- Integration of frontend framework Angular and Ionic with backend NodeJS API's.- Develop features across multiple subsystems within our applications, including collaboration in requirements definition, prototyping, design, coding, testing and deployment- Provide engineering support when building, deploying, configuring and supporting systems for Linkagoal members.- Maintain hosting services.
