I am a driven full-stack developer and genAI builder, combining technical skills with a user-centric approach.  I'm seeking opportunities in mission-driven companies for building innovative products. Let’s connect!

Here's my story :)
Walked through Carnegie Mellon's doors, ambition in my heart,
Majored in Statistics & Machine Learning, and Computer Science, a future to impart.
Learning data structures, algorithms, systems, UI/UX design,
On a full-stack path I embarked, where tech and user needs align.

In CMU's labs, human-robot interaction, a frontier to explore,
Building interactive systems, exploring social robots and human creativity to the fore.
At the Technology for Effective Learning lab, crafting Python course,
More effective, more efficient, for thousands of students to learn more.

In the sphere of Cassian Solutions, where healthcare meets tech's embrace,
From UI design to full-stack, proficient in Figma, React, and TypeScript.
Enhancing patient engagement, machine learning weaves its intricate lace,
Serving tens of thousands, delivering a user experience smooth and ace.

RealChar, my open-source venture in generative AI,
Users create, customize, audio-call AI companions, where tech and humanity intertwined.
Leveraging large language models, voice clone and synthesis, and audio streaming,
Guided the project to 5.4k stars, a victory at the AGI House Hackathon we bring.

Transitioning from startups to Amazon's expansive domain,
Scaling skills, deploying AWS infrastructure to automate large-scale data's chain.
Leading Science Paper Repository to make searching internal paper an easy game,
Collaborating with PMs, designers, engineers, aligning user needs with tech's seamless frame.

For a mission, a vision, in technology's vast sea,
Embracing challenges, where I'm meant to be.
Driven by passion, in the tech world's scheme,
I build, I create, chasing the big dream.
