About Me
👋 Hey, I'm Vishnu!
Data Engineer @ Dataparts.ai | Building data foundations for LLM and AI applications
I’ve worked across data engineering, analytics, and applied AI, from building AI-powered assistants to setting up reporting systems and automating workflows. I enjoy working close to both the data and the code, and I’m comfortable moving between business requirements and technical implementation.
I care a lot about building things that last. That means prioritizing reliability, clear data models, and simple designs over over-engineering. My goal is always to make data easier to trust, easier to use, and genuinely helpful for decision-making.
âš¡ My Superpower?
Merging deep technical expertise with a product-driven mindset. I focus on building AI systems that work—systems that align with business goals, user needs, and operational realities.
âš½ Off the Clock:
You'll still find me on the soccer field or backing Manchester United (through thick and thin). Data, football, and a bit of code—that's my game plan.
🚀 Let's Connect!
Whether you're building with AI, solving complex business challenges, or just want to talk models and matches, I'm all ears. Let's create AI that actually delivers.
