About Divyansh Kumar
I’m a Senior Full-Stack Engineer with 5+ years of experience building high-performance, user-centric web and mobile applications. My expertise lies in React.js, FastAPI, and data visualization, where I transform complex datasets into intuitive, scalable front-end experiences.At Needle Digital (Australia), I developed a React + Mapbox geospatial platform that handled billion-record datasets by implementing MBTiles and optimized API queries—reducing load times by 80% and eliminating memory overflows. I also architected Neo4j graph database solutions that cut query response times by 75%, enabling seamless real-time exploration of geological data.Previously, as CTO at WellM (post-acquisition of my startup), I scaled a mental wellness platform from a Flutter mobile app to a responsive React web platform. I drove a 250% increase in user retention by designing a data-driven engagement system, and successfully led product and technology integration across teams.My experience spans startups, enterprise consulting (Publicis Sapient), and global remote collaboration. With a strong foundation in React, Next.js, FastAPI, Neo4j, AWS, and Docker, I bring both hands-on engineering skills and a CTO-level product mindset to every project.I’m passionate about building scalable architectures, high-impact data visualization tools, and remote-first products that deliver measurable business value.Let’s connect if you are looking for someone who can help you trying to build a vision with technology. Would love to know more.
