Built a chat with your data application with RAG techniques and fine-tuned versions of popular LLMs Built an Automated call recording audit system that transcribes and extracts key information from voice calls - to improve customer satisfaction and identify potential abuses that might otherwise go unnoticed in manual audits Built a Vector-based, low latency search system (trained from scratch) - to smartly rank the most relevant products for search queries on e-commerce platformsBuilt the ETL pipelines from scratch and also built a demand forecasting model using Gradient Boosting methods for an e-commerce client

Planned the events to be captured and designed the event data pipeline to track customer behaviour across the Veera Browser Android applicationCreated the ETL pipelines and transformed the raw data for consumptionBuilt Key KPI dashboards that helped product teams understand the highest retention levers and gaps in the Android app

Designed experiments for Focused targeting for fruits and vegetables campaign - leading to better retentions using Simple Market Basket Analysis which led to increase in customer penetration (from 33% to 38%). Built a customer-level new item propensity model basis Catboost model, which was used to predict if a customer would like a product even before they’ve seen it - this helped us to optimise inventory across dark stores, also built ETL pipelines to generate the features needed for the machine learning model Identified POI (Apartments) wise purchase patterns of different categories and assisted the category managers in the planning of BTL campaigns at apartments and societies to increase brand awareness and run discountingClustered search keywords using vector embeddings (Sentence Transformers) and then utilised it to identify bumps in demand for specific SKUs that helped in customising product catalogues for festivals - overall Blinkit was able to achieve the highest ever sales during festivals with this approachCreated an ops visibility dashboard from scratch that helped in optimising the supply chain operations at the inbound stage of Blinkit Warehouses - This helped in better scheduling and quicker inwarding of products from vendors.

Built the ETL pipeline to track chat support metrics, earlier a manual process where KPIs were visible at the current+1 dateExtensively worked on improving chat user experience thru workflow design + aided it with automation - DialogFlow. Overall, this improved CSAT from 50% to 70% and increased the customer response Rate from 1.5% to ~ 15% for CSAT surveysBuilt an SQL tool - a heuristic-based Employer Complaints fulfilment tool for RCAing issues in job postings. That was later used by Sales + Ops + Misc. Internal stakeholders

ETL/Data Engineering side: I understood data flow between legacy database systems (earlier unclear), helping the data team get the key fields for 99%+ cases, earlier ~ 60-70%Proactively worked to monitor the server, and BI tool health, automate data structure backups, automate batch runs, optimise data structures, and set up the Grafana framework to monitor the BI serversReceived the organisation's Super Star Award for AMJ - 2021 for the automation, server monitoring efforts

Spent time with my family, did some pondering to figure out what my strengths were. And pivoted to a new discipline with a first principles thinking approach (always has been my strength).

Gurgaon, Haryana, India

Executed Oil and Gas design projects and provided after-project support for 4 oil and gas refinery projects - KIPIC, Indian Oil, ZPC etc. Along with ongoing projects, provided support to numerous projects for Pressure Relief Valve Calculations like PC GuangdongAwarded the Honeywell Bravo Award for exceptional performance in the first project assignment

Novel Catalytic Materials, IH2® TeamInvolved in developing the first principle-based computational model for complex multi-phase reaction systems. The project was to aid in the commercial deployment of a novel breakthrough process. Closely coordinated with researchers and developed models based on novel research data.- Developed Single Particle Models at the start using MATLAB, which could explain the behaviours observed in experimental data- Introduced complexity by including additional convective effects in the mass and energy transport equations- Explored applicability of Lattice-Boltzmann methods for simulating complex systems, explored the feasibility of simulating large scale reactors for the novel process, LBM offers significant parallel computation benefits- Helped experimental team design future experiments based on understanding from literature review and modeling results
