Hi, I'm Nikita Mandal ๐Ÿ‘‹

Machine Learning & Systems Engineer | Edge AI, Sensor Fusion, Signal Processing & Robust Deployment

LinkedIn ๐Ÿ“ง mandal.n@northeastern.edu

I am an ML Engineer focused on deploying high-performance deep learning models to resource-constrained edge devices. My engineering philosophy is rooted in systems reliability: before specializing in AI, I spent two years designing SIL4 safety-critical Train Control Systems at Alstom. I don't just optimize for accuracy in a notebook; I optimize for fail-safe execution, deterministic latency, and real-world edge cases.

Currently wrapping up my MS in Electrical and Computer Engineering at Northeastern University and recently engineered real-time radar/camera fusion pipelines at Aura Intelligent Systems.

I am actively seeking full-time roles where I can build reliable, deployment-ready AI systems.

๐Ÿš€ Featured Work

1. High-Performance C++ Inference Engine for Edge Robotics

Engineered a custom C++ inference engine from scratch to bypass Python's GIL for real-time robotic perception.

  • Impact: Increased throughput by 1.36x (15.0 FPS to 45.0 FPS) on CPU-only hardware and implemented zero-copy memory management.
  • Tech Stack: C++, ONNX Runtime, OpenCV, CMake, YOLO11

2. Real-Time Spectral Signal Decoder (BrainStorm Hackathon - 2nd Place)

Designed a real-time causal streaming pipeline to classify high-density ECoG sensor data for brain-computer interfaces.

  • Impact: Won 2nd place by compressing the model size to 150KB (16x reduction) to fit wearable memory limits, while hitting a strict 35ms latency budget.
  • Tech Stack: PyTorch, Signal Processing (FFT), TorchScript JIT, Model Compression

3. End-to-End MLOps Pipeline for Continuous Deployment

Architected an automated ML pipeline on the cloud for time-series anomaly detection and forecasting.

  • Impact: Reduced manual retraining by 80% using statistical data drift triggers (K-S test) and accelerated release cycles by 40% via containerized CI/CD workflows.
  • Tech Stack: GCP (Vertex AI), Apache Airflow, Docker, FastAPI, MLflow

4. Adversarial Robustness in Safety-Critical Vision Models

Investigated edge-case failures and safety vulnerabilities in deploying deep learning models for high-reliability systems.

  • Impact: Engineered a hybrid defense strategy recovering >75% robustness under rigorous PGD sensor attacks, proving Vision Transformers are 11% more resilient to localized noise than CNNs.
  • Tech Stack: Vision Transformers (ViT), CNNs, Adversarial ML (PGD/Patch)
