1] Project integrated with Meta’s LLaMA 3 model in Spring AI for integration with firm services and client products.

• Designed & developed an app from scratch in Spring boot that integrated with Ollama platform hosted on a docker container.
• Leveraged Meta’s LLaMA 3 large language model to produce generative text response to the user prompt.
• Provisioned with chat client to integrate with Ollama service in order to send prompts and receive response for these prompts.
• Functionality: Hosted on Private Cloud, built upon Spring AI LLMs, Java 21 & Springboot, this app allowed users to send a prompt to the application and receive a response to their respective prompt.
• Solution/Benefit: Completely built using open-source frameworks and tools helped the firm save material cost on development as well as services. The product served as a benchmark to approach multiple stakeholders to earn more business from potential customers and buyers looking for a similar solution.
• Future Enhancements: To add integration to integrate OpenAI and other Language models into this product to diversify the user experience and have them opt for a generative source to leverage upon their own platforms in the form of microservices.

2] RAG(Retrieval Augmented Generation) model with Spring AI for integration with firm services and client products (‘24) :

➢ Implemented RAG model that stores documents into the vector store database in the form of embeddings.

➢ Created embeddings out of business documents such as PDF files, texts and further stored the embeddings into the vector data store.

➢ Leveraged LLaMA3.1 model to produce generative responses in natural language to the user prompts injected within Spring Templates along with vector store.

➢ Functionality : Hosted on Private Cloud, built upon Spring AI, LLMs, Java 21 & Springboot, this app allowed users to send a prompt to the application and receive a response to their respective prompt.

➢ Solution/Benefit : Apart from saving material and development costs, private entities and large firms could now retain data privacy and confidentiality as the documents won’t be shared over the internet and everything would be local/within the organization’s intranet and under control.

➢ Future Enhancements - In Progress : Implemented Multimodal capabilities to process and describe images in natural language.

3] LLM model integration with TTS(Text To Speech) (‘24) :

➢ Developed TTS (Text To Speech) framework and integrated it with LLaMA 3.1 model to produce human voice for the responses to the prompts generated by the LLM model.

➢ Functionality : Hosted on Private Cloud, built upon Spring AI, LLMs, Java 21 & Springboot, this app allowed users to send a prompt to the application and receive a response the human voice that reads through the response.

➢ Solution/Benefit : Business team has an AI/ML model of their own that can produce speech to the smart responses produced by the language model with zero additional cost. Side kick - Blockchain : Exploring to see how I could best leverage this area to provide solutions to complex business problems.

➢ Functionality : Bank received trade information for trades such as SWAP, SWAPTION, FRA, FX, FXSWAP, CAPFLOOR and few others from the up streams., The settlements department shall process, settle the trade and further send to downstream systems.

➢ Solution/Benefit : Hosted on banks private Enterprise Cloud Platform, this application indeed a system provided trade settlements by reading the JSON files received through events from the source and then converting it to XLMs using XSD and sending further to other dependent downstream apps of the bank. This helped the department to continue with the trade settlement solutions after the source decided to upgrade their platform to leverage JSON instead of XMLs which would have otherwise caused the bank to break its entire implementation and business workflow.
