Hello, I'm
Harsh Maheshwari
Software Engineer & Researcher
Computer Science & Computational Mathematics student at Penn State. Building intelligent systems and pushing the boundaries of AI.
About Me
I'm a Computer Science and Computational Mathematics student at Pennsylvania State University with a passion for software engineering, machine learning, and research. Currently maintaining a 3.8/4.0 GPA.
My experience spans from developing AI-driven platforms to conducting research on bias in large language models. I've worked with diverse technologies including React Native, AWS, Flask, and various machine learning frameworks.
As a former CTO at Marble, I led development teams using Agile methodologies and shipped products that make a positive impact. Currently, I'm working on frontier AI safety at Scale AI and building healthcare solutions at SIGNUM.
Experience
My professional journey across AI, software engineering, and research.
GenAI Technical Advisor Intern
Scale AI
San Francisco, CA
- • Prompt-engineered frontier LLMs; wrote 150+ tests (reasoning, tool-use, safety, retrieval); fixes cut jailbreaks/hallucinations by 20–30%.
- • Systematically tested LLM tool-calling strategies; rewrote instructions and examples, improving model's adherence to complex instructions by 12% and decreasing tool errors by 10%.
Software Engineer
SIGNUM
State College, PA
- • Designed and developed a React Native app; Migrated backend services on AWS increasing the security and efficiency by 20%.
- • Engineered and launched geofencing and wearable event processing features, increasing caregiver response time to critical events by 25% and contributing to enhanced patient safety and well-being.
Research Intern
College of Information Science and Technology
State College, PA
- • Publishing a research paper as the lead author on the bias by LLM's on 20+ stereotypical subjects by Llama 2 7B using graphs.
- • Developed Python scripts and Jupyter notebooks to automate data collection, leveraging Flask API to retrieve model responses from various LLM models on Hugging face
Chief Technical Officer
Marble
State College, PA
- • Launched an AI-driven mental-health platform; led a Next.js/React/TypeScript web MVP with Node.js APIs and Flask microservices integrating AWS, Firebase, OpenAI, and ElevenLabs.
- • Shipped MVP in under 4 weeks (team of 4), achieved 50+ downloads in week 1, incorporated feedback from 300+ user interviews, and secured $7.5K in awards.
Software Engineering Intern
Penn State College of Medicine
State College, PA
- • Developed a cross-platform React Native clinical-support app with Firebase synchronization and role-based access; coordinated 20+ beta tests and shipped on time.
- • Collaborated in an agile team of 5; delivered reusable UI components and analytics aligned with clinician workflows.
Software Engineering Intern
World Hope
State College, PA
- • Architected a Python RAG backend with MongoDB enabling fast retrieval and AI Q&A for caseworkers; designed for 1,000+ field users serving 100,000+ beneficiaries.

Projects
A selection of projects I've built, from AI-powered tools to award-winning hackathon submissions.
Predictive execution co-pilot for Slack/Teams that connects to Jira, Slack, OKR platforms, and wikis to detect misalignment and risks early. Created a working MVP within 1 month. Impact: earlier blocker detection; managers save approximately 4 hours/week on status updates.
Built tumor and Alzheimer's classifiers on 300+ DICOM CTs with 3D visualization via VTK; achieved accuracies up to 94% and 80%. Won 1st place in Generative AI category at HackPSU.
Collaborated with a team of five to design and create a real-time ASL Translator app with an accuracy of 87%, delivering third-place success in a competitive Hack PSU event.
