Featured Projects

Retinal Disease Classifier — FLAIR vision-language model for diabetic retinopathy and glaucoma detection
01
PyTorch FLAIR Computer Vision

Retinal Disease Classifier

Designed zero-shot and linear-probe experiments with the FLAIR vision-language model for diabetic retinopathy and glaucoma detection, achieving 0.92 AUROC with only 5-20% labels.

Forge — Training data engine that generates, evaluates, fine-tunes, and benchmarks with statistical significance
02
Python MLX LLM-as-Judge

Forge

End-to-end pipeline that generates multi-strategy training data from documents, scores every example with rubric-based LLM-as-judge evaluation, detects benchmark contamination, fine-tunes a model locally with LoRA on Apple Silicon, and proves improvement with paired bootstrap significance testing. 184 tests, +16.8% ROUGE-1 gain.

Auth Microservice — Production-grade authentication service with JWT, MFA, and OAuth
03
Node.js TypeScript PostgreSQL

Auth Microservice

Built a production-grade authentication service from scratch with JWT RS256, TOTP-based MFA, OAuth (Google/GitHub), refresh token rotation with theft detection, Redis rate limiting, and 136 automated tests.

About Me

Pugalenthi Magendran — Graduation

I'm an AI / Machine Learning Engineer with a Master of Artificial Intelligence from Monash University. My work spans foundation models, large language models, and computer vision — from building retinal disease classifiers to fine-tuning LLMs for text-to-SQL generation.

Currently a Business Fellow at Perplexity AI, I prototype LLM agent workflows and explore AI product strategy. I'm passionate about taking projects from experimentation through to production-ready tools and demos.

Experience

Business Fellow (AI Product & Research)

Perplexity AI

Feb 2025 — Present Current

Selected into a competitive fellowship focused on AI product strategy and LLM-powered workflows. Prototyping no-code and low-code LLM agent workflows to automate internal analysis tasks.

AI Researcher — Foundation Models

Monash University

Feb 2025 — Nov 2025

Designed experiments comparing zero-shot vs linear-probe adaptation of the FLAIR vision-language model for retinal disease detection. Built reproducible Python/PyTorch pipelines for the full research workflow.

Venture Capital Analyst
