About Me

name: Nilanjan Royrole: Full-Stack Engineer @ Vertige (Healthcare AI)education: M.S. Software Engineering + AI · Northeastern '25focus: Real-time distributed systems · Applied LLMs · Mobile productsmantra: "Reliability over novelty. Latency you can feel. Code that ships."

The Road So Far

🩺 Vertige Full-Stack Engineer Jan 2025 — Present Philadelphia (Remote)
💼 Cynet Systems Full-Stack Engineer Sep 2022 — Aug 2023 Noida, India
🎟 Mastech Digital Full-Stack Engineer Jan 2021 — Sep 2022 Noida, India


Things I've Shipped

🎨 Canvas2Code

Image → working code, in real-time.

Multimodal LLM pipeline with SSE streaming, Postgres-checkpointed conversational state, Redis-cached vision-judge calls, per-provider budget circuit breakers, and an automated eval harness scoring visual fidelity, element presence, and code validity.

📈 LynchBot

Peter Lynch as a chatbot. RAG, no API keys.

Financial RAG chatbot with FLAN-T5 generation + Sentence-BERT semantic search, an async embedding pipeline with custom caching, and LLM eval workflows benchmarking retrieval quality against unstructured financial datasets.


What I Optimize For

Reliability over novelty — zero-rollback releases · fault-tolerant Kafka · JUnit-first
Latency you can feel — 30% retrieval gains · 18% page load cuts · <5s cold starts
Code that ships — 5 years of production microservices, mobile apps, and AI systems users actually touched


Always open to interesting problems. Reach out 📬

 The Road So Far
🩺 Vertige Full-Stack Engineer Jan 2025 — Present Philadelphia (Remote)
💼 Cynet Systems Full-Stack Engineer Sep 2022 — Aug 2023 Noida, India
🎟 Mastech Digital Full-Stack Engineer Jan 2021 — Sep 2022 Noida, India


 Things I've Shipped
🎨 Canvas2Code
Image → working code, in real-time.
Multimodal LLM pipeline with SSE streaming, Postgres-checkpointed conversational state, Redis-cached vision-judge calls, per-provider budget circuit breakers, and an automated eval harness scoring visual fidelity, element presence, and code validity.
📈 LynchBot
Peter Lynch as a chatbot. RAG, no API keys.
Financial RAG chatbot with FLAN-T5 generation + Sentence-BERT semantic search, an async embedding pipeline with custom caching, and LLM eval workflows benchmarking retrieval quality against unstructured financial datasets.

 What I Optimize For
Reliability over novelty — zero-rollback releases · fault-tolerant Kafka · JUnit-first
Latency you can feel — 30% retrieval gains · 18% page load cuts · <5s cold starts
Code that ships — 5 years of production microservices, mobile apps, and AI systems users actually touched

Always open to interesting problems. Reach out 📬
