Work History
12Years
Senior Developer
SAP Labs IndiaApr, 2020 - Present5 yr 6 months
Led design and deployment of ASR pipelines for Hindi and English using NVIDIA NeMo Conformer, IndicWav2Vec, and IndicConformer. Curated diverse datasets covering read, spontaneous, and conversational speech. Fine-tuned NeMo models to reduce domain mismatch. Benchmarked CER, WER, latency, real-time factor, GPU/CPU utilization, and scalability. Deployed training workflows on AWS multi-GPU cloud infrastructure. Developed speech data collection platform and re-architected SAP Translation Hub migration with Kubernetes deployment. Evaluated NMTs for Indic languages and improved short-text language detection for enterprise scenarios.

ShrutiLekha Indic Speech Data Collection Platform
Developed a full-stack speech data collection and review tool for Indic ASR. Features include prompt assignment, recording interface, reviewer scoring, and S3 storage integration. Built with React, Flask, PostgreSQL, Docker, AWS EC2/S3, and NGINX.
Translation Hub
Re-architected SAP Translation Hub migration from Neo HANA Cloud with Kubernetes deployment. Designed schemas, tables, stored procedures, views, indexes, and flowgraphs in HANA Cloud. Built ETL pipelines and migrated legacy services into Java.
Evaluating NMTs for Indic Languages
Conducted comparative analysis of SAP NMT vs IndicTrans2 for English-Hindi translation. Evaluated translation quality using BLEU, METEOR, TER, ChrF, and COMET. Fine-tuned Indic models and experimented with ensemble approaches.
Investigation on Short Text Language Detection
Improved language detection for tweet-length SAP text. Benchmarked LangDetect, Ldig, and FastText. Created new short-text datasets and fine-tuned models for accuracy and robustness.
Multi-Agent VQA (VideoMultiAgents Reproduction), Research Work
