Work Experience
AI Developer
OmniThrive Technologies
- Built an AI-powered financial research agent that automates the collection and summarization of financial reports and stock market trends. The agent integrates LLMs, vector databases, and automated workflows to provide real-time investment insights.
- Conducted LLM engineering and financial reporting using RAG. Used LangChain and OpenAI API to extract and analyze stock earnings transcripts, news articles, and SEC filings. Implemented LlamaIndex for structured retrieval of historical trends.
- Built an Auto-GPT agent to autonomously scrape, summarize, and compare financial data. Used OpenAI function calling to connect the AI agent with APIs for real-time stock market monitoring.
- Used Pinecone and Neo4j to store and retrieve financial data based on entity relationships (e.g., CEO mentions and company performance correlations). Graph-based queries enabled tracing relationships between news events and financial policies.
- Deployed the AI agent as a containerized solution with Docker and Kubernetes. Optimized inference pipelines using serverless GPU inference with AWS Lambda and NVIDIA Triton.
- Developed a Flask-based API that connects to ChromaDB for semantic search across indexed company documents. Implemented SurrealDB as a hybrid SQL/NoSQL solution to store structured metadata for document classification.
- Implemented Neo4j for relationship mapping to visualize document connections and expertise within teams. Allowed employees to query the AI system for insights, such as "What are the top security risks discussed in the last three months?".
AEM Lead Developer
Shell
- Re-implemented the order chat table for Shell MarketHub 1.0 Marine, entirely restructuring the marine lighthouse table, order details page, and views management functionality. I was awarded as the best individual contributor in 2018 (Q1).
- Prevented multiple requests made to the AEM back end to fetch the same menu that JSON required on every page of the SMH. I used client-side caching, resulting in page loads of MarketHub (except Hybris pages) that were faster by 750ms to one second.
- Performed adaptive image renditions based on the size and location of the page. For all the heavily sized images, suitable image renditions were generated and used according to the size of the image container.
- Built the integration in the AEM back end to use the Salesforce REST API for contact creation and updates on the contact flow, contact de-activation, and deletion for the project blaze. SMH uses Salesforce CRM through an API built with Apigee.
- Re-implemented the Shell MarketHub login page through a new login and landing page to make it completely authorable.
- Integrated Buto.tv in four AEM components, allowing SMH to enable Buto.tv-hosted video accessibility on SMH pages.
- Implemented lazy images to decrease page load time by loading them asynchronously to the page load event.
- Worked as a technical lead and developed the Marine GSAP integration project from January to March 2020. This enabled action status updates to flow from GSAP to Marine, reducing COS efforts.
- Recognized with the best-performing team award in 2020 (Q1) and the SMH People Choice award in October 2020 (Q4).
- Implemented AEM Adaptive Forms using context-aware Adaptive Form fragments and JSON schemas, which were built to help marketing teams build dynamic forms that change as per the market/country/region from where the end users were accessing it.

- Integrated the system with Adobe tools like Search&Promote, Scene7, Adobe Target, and DTM.
- Built custom widgets and custom search functionalities.

Experience
Shell MarketHub
https://www.markethub.shell.com/My technical responsibilities included:
• Development of new reports and widgets (for the US fuels business) and Sightly components, modification of old JSTL and JSP components, OSGi services, custom workflows, Sling schedulers, custom JCR event listeners, and Sling servlets.
• Integration with NGAP and the relational database.
• Integration of the following services with AEM (UAM): Salesforce CRM, microservices, SOAP web services, and REST services (Shell legacy applications exposing REST services or integration with third-party REST services).
• Microservices implementation with Sprint Boot for the aviation business.
• Development of modules for marine, aviation, and UAM.
• Leading cross-business implementation activities for marine, aviation, blaze, and AEM/UAM CRs.
WEGMANS
https://www.wegmans.com/As part of this project, we started by identifying the base page and home page templates, recognizing the reusable components required to be developed apart from reusing the out-of-the-box components. We also performed integration with Target and DTM and handled content migration scripts to migrate their thousands of products and recipes.
Under Armour Brand
https://www.underarmour.com/UnderArmour brand was one of the most complex projects that Adobe handled. This project required a lot of customization of AEM assets functionalities to suit the client's requirements. We heavily customized AEM project creation, AEM assets search and replication functionality (activation and de-activation), and collections. We created a new site called "Vendor Portal" where only the published assets would reside ordered by brands and published date. Many custom workflows were designed to handle expired assets, automatically de-activating them from being published, moving projects to a different location based on the attributes selected while project creation, creating custom renditions when assets are uploaded, and more. Also, we performed integration with InDesign, making assets modified in InDesign automatically available in AEM and vice versa—a two-way synchronization.
