Vatsal Jha
I'm a research engineer working on reliable AI systems and sequential decision-making.
I build multi-agent systems, reinforcement-learning methods, and the ML infrastructure to run them. Recent work includes a root-cause diagnosis system for distributed services at Samsung Research, a bandit-based planner for EV charging infrastructure, and audio-deepfake detection at testAIng.
I recently completed a B.Tech in Computer Science & Engineering at Vellore Institute of Technology.

Selected Work
Agentic root-cause analysis for distributed services
Designed and built a multi-agent root-cause diagnosis system end to end: specialist evidence collection, hypothesis validation, cross-incident retrieval memory, and diagnosis-only safety boundaries, using Google ADK and MCP over Kubernetes and observability infrastructure. Evaluated it on a purpose-built fault-injection testbed (OpenTelemetry Demo plus Chaos Mesh).
HOMA: multilingual agent orchestration for smart homes
Led a four-person research team building a multilingual SLM-orchestrated system that decomposes multi-device smart-home commands and coordinates sequential and concurrent execution across 11+ languages, with synthetic multilingual evaluation of Gemma, Qwen and Phi-family models under edge constraints.
HERO: EV charging-station placement via bandit search
A two-stage system for EV charging-station placement: an XGBoost city-level demand model feeds a simulator-in-the-loop multi-armed-bandit search over full station layouts. In Ann Arbor SUMO microsimulation, it outperforms facility-location, metaheuristic and bandit baselines by up to 39.9% composite reward; results are reported in a manuscript currently under review.
PrompTrend: contextual-bandit prompt recommendation
A FastAPI service that recommends prompts online using contextual bandits: BERT intent classification, Redis/PostgreSQL persistence, and feedback-driven incremental regressors under stochastic exploration. Published as an installable package.
Multilingual audio deepfake detection
Owned ML systems and research for multilingual audio-deepfake detection (ECAPA-TDNN, WavLM, mixture-of-experts), reaching 0.94 to 0.96 AUC on internal multilingual benchmarks and 1.97% EER on Hindi fine-tuning, then migrated model-heavy inference to Docker/Kubernetes with HPA, probes and Prometheus/Grafana.
ChatterBot: a scalable LLM-serving prototype
FastAPI, Ray Serve/vLLM, Redis, RabbitMQ and PostgreSQL serving system with synchronous, queued-async and SSE streaming modes, context caching, retries and circuit breakers, and Locust load tests. Designed to scale horizontally under high concurrency.

About
Outside of research, I co-founded Team Prometheus, VIT's RoboCup Small-Size League team, and later led Youth Red Cross, VIT, where I organized a blood donation camp that set the university's single-day record. I grew up in Bokaro and am currently based in Bangalore.
