Retrieval Augmented Answer Generation• Engineered a novel answer generation system to extract relevant informationfrom vast corpora & generate responses to user inquiries• Reduced around 99% cost per query, removing dependency on OpenAImodels, integrating Falcon-40B, LLama-2-70B via vLLM• Designed and implemented the pipeline for data acquisition, processing,& indexing through Lucene, optimizing retrieval efficiency• Leveraged embedding models to generate vector representations ofdocuments and queries, enabling semantic similarity-based retrievalZero-Shot and Few-Shot Intent Classification• Combined Setfit with LLMs gaining almost 25% intent prediction f1score, overcoming data scarcity, & made it available as a feature• Used Llama-2 after finetuning with LoRA, reducing GPU utilisation,time, resources, & leveraged gRPC calls to establish cross domain communicationfor efficient and fast information sharing• Conducted extensive research, testing& prompt engineering of variousLLMs & embedding models, deploying the most effective solution

Delivery Centre Centroid• Worked closely with the ground team to recommend optimal deliverycentre geocoordinates using Kmeans clustering algorithm• Saved around 30% Last Mile operational cost using past data, recommendingoptimal dc location following business constraints• Managed relocation, split, closure cases of DCs on PAN India level• Visualized the results on a folium map, with heatmaps, hotspots etc.Box and Flyer Prediction• Trained a deep learning image classification model using VGG16 on Tensorflowto predict Box & Flyer images with 94% accuracy reducing morethan 14% cost per shipment• Automated the code using multithreading to download, load& process30 lakh images daily using boto3 from s3 bucket on ec2 instanceGeocoder Misrouting• Input Address -> Geocoder -> Address Coordinates• Processed and analysed geocoder data via sql queries, recommendingways to increase accuracy of geocoder, minimizing overall misrouting• Analyzed trends on a PowerBI dashboard to find patterns of intercityand intracity misrouting, distribution percentages etc• Converted address text to vectorized form using Tf-IDF and fed intoLSTM model to classify bad addresses with 96% accuracy

- Devised an efficient architecture of activities to train 70+ students on departmental level by ideating GDs, PIs, formulating tests, etc.- Teamed up with a group of 55+ DPCs to examine the resumes of 1600+ students across 23 departments for preserving authenticity- Acted as a bridge between the placement cell & students for smooth functioning of activities & flow of information among them

- Coordinated with a team of 250+ members for interviews of 1600+ students- Assisted in conducting Pre-placement Talks and Tests for 15+ firms.

• Coordinated with a team of 100+ members to design the architecture and management of cultural programs in Espektro'18, the Annual Techno-management cum Cultural fest of KGEC.• Organized and implemented various cultural activities all the year-round though Riyaz, in KGEC.

• Spearheaded a team of 50+ members to successfully organize and supervise the events at Alfresco'18, the Annual Hall Day cum Reunion of Rishi Bankim Chandra Hall.• Responsible for the management and implementation of various cultural activities in RBC Hall.
