Industry Experience - Alstom Cybersecurity Internship Cybersecurity Analyst Intern at ALSTOM (Regional APAC Cybersecurity Dept) (May 2025 - July 2025, Bangalore, India (Hybrid)). Ran the Initial Risk Assessment for Alstom's R1 railway signaling system under IEC 62443. Mapped a 4-zone trust architecture across Depot and Main Station topologies, then authored a 40-page technical specification covering 23 industrial cybersecurity risks.
Ran the Initial Risk Assessment (IRA) across Alstom's R1 railway signaling topology, identifying trust boundaries and conduit vulnerabilities across CBI, ATC, and ATS subsystems. Mapped 4 trust zones (A through D) with 25+ sub-zones, establishing zone-specific Security Level Targets and 5 formal conduits (CDT-01 to CDT-05) with MACsec, IPsec, and 802.1X NAC controls. Authored a 40-page technical specification defining defense-in-depth mitigations for 23 industrial risks, reducing 6 Very High and 8 High severity ratings to 0 post-mitigation.

Authors: Dr. Punit Gupta, Liza Chaurasiya, Vyom Uchat. DOI: 10.1007/978-981-92-1030-5_19. Abstract: Tropical cyclones are high-impact meteorological events whose timely and accurate detection is critical for public safety. This research provides a rigorous comparative analysis of two lightweight object detection models, YOLOv8n and YOLOv11n, trained on the INCYDE satellite imagery dataset. Benchmarked using mean Average Precision (mAP), YOLOv11n on unaugmented imagery achieved superior performance with mAP@.50-.95 of 0.921 and detection recall of 0.994. Counter-intuitively, standard geometric augmentations degraded performance across both models, demonstrating that data strategies must be domain-aware.Metaheuristic Task Scheduling Optimization Algorithm for Edge Computing : A Review (2026) - Published in OPSEARCH, Springer. Authors: Vyom Uchat, Dr. Punit Gupta, Aaditya Jha, Tejash Karamata. DOI: 10.1007/s12597-026-01293-w. Abstract: Time-critical IoT applications require intelligent offloading across the Edge-Cloud continuum. Juggling tasks in dynamic environments is NP-hard. We benchmarked 10 scheduling algorithms across heuristic, metaheuristic, game-theoretic, and reinforcement learning paradigms on latency, power draw, and SLA violation rates. Standard off-the-shelf implementations suffer from slow convergence and local optima traps under network congestion. This review maps key trade-offs and architectural requirements for real-time edge schedulers.Queuing Search Algorithm Metaheuristic Task Scheduling Algorithm for Cloud-Edge Computation (2025) - Under Peer Review in OPSEARCH, Springer (Under Peer Review). Authors: Vyom Uchat, Dr. Punit Gupta, Aaditya Jha, Tejash Karamata. DOI: Under Peer Review (OPSEARCH, Springer). Abstract: Task scheduling across the Cloud-Edge-Mist continuum is an NP-hard resource allocation challenge. We propose a task scheduling framework built around a tailored adaptation of the Queuing Search Algorithm (QSA), inspired by human queuing behavior to gravitate solutions toward faster service regions while avoiding local optima. Integrated with the PureEdgeSim simulation toolkit across 300 devices and 30,450 tasks, QSA reduced average task execution delay by 55% (0.218s vs 0.4874s for Genetic Algorithms) and achieved a 99.9% task completion rate across the full three-tier architecture.Technical Skills and Stack AI, ML and Automation: Retrieval-Augmented Generation (RAG), FAISS, Sentence-Transformers, Llama 3, Groq API, Google Gemini Vision and Multimodal API, Groq Whisper, Qdrant Vector DB, PyMuPDF, YOLOv8, YOLOv11.
