Kartikey Khanna
Software Engineer passionate about building resilient architectures, integrating AI/ML into real-world platforms, and simplifying complex workflows into impactful products.
Hi, I'm Kartikey Khanna, a software engineer passionate about building scalable systems, resilient architectures, and intelligent solutions that merge cloud, data, and AI.
My journey started with curiosity about how technology shapes the world, and it's led me to hands-on experience across backend, frontend, and AI/ML. At Bajaj Finserv, I've engineered microservices powering financial products, automated real-time data synchronization with Azure Cosmos DB, built intelligent query systems using large language models, and designed forecasting solutions to predict API traffic and failures. Alongside this, I've contributed to frontend and blockchain projects, proving that depth and breadth can coexist.
I refuse to fit the mold of a jack of all trades, I'm redefining it. Mastering backend, cloud, and AI, I thrive at the crossroads of disciplines, turning complexity into elegant, end-to-end solutions that push the boundaries of what's possible.
Beyond work, I've been recognized among the Top 10 Interns at Bajaj Finserv DevTalk 3.0, a Top 36 finalist at HackRx 4.0, and a Top 50 finalist in the Amazon ML Challenge. These milestones remind me that growth comes from pushing boundaries and embracing new challenges.
Let's collaborate to turn ambitious ideas into scalable realities.
