About

As a passionate Full Stack Engineer with over two years of experience, I specialize in building robust and scalable web applications. Currently, I am a founding member of TalkingLands, an innovative prop-tech startup where I’ve played a pivotal role in scaling the product from 50 MAU to 2000 MAU and developing revenue models. My technical expertise spans both frontend and backend technologies, with proficiency in Vue.js, Nuxt.js, ReactJS, and backend services like AWS Lambda, GraphQL, and REST APIs. At TalkingLands, I have led significant projects, including revamping the platform with a new frontend stack, migrating map technologies, and implementing event-driven architectures. My hands-on experience with AWS services, such as AppSync, DynamoDB, EventBridge, and Cognito, has enabled me to develop efficient, serverless solutions tailored to our business needs. I’ve also contributed to the patent "System and Method for Providing Chromatic Lens Framework Based User Specific Geospatial Recommendation and Insights," reflecting my dedication to innovation. I thrive in dynamic environments, tackling challenging problems with creative solutions. Currently, I’m focused on building a SAAS product for TalkingLands, working with microservices using NestJS, MongoDB, and PostgreSQL. My enthusiasm for new technologies drives me to continuously learn and adapt, ensuring that I deliver top-notch solutions that bridge technology and business. I am always eager to connect with fellow tech enthusiasts, exchange ideas, and explore opportunities that push the boundaries of innovation. Let's connect and drive the future of technology together!
