Contribute to CI/CD automation and maintain operational stability of application services.
Generative AI & Model Optimization:

Fine-tune LLMs/SLMs with proprietary NBFC data.

Perform distillation, quantization of LLMs for edge deployment.

Evaluate and run LLM/SLM models on local/edge server machines.
Self-Learning Frameworks:

Build self-learning systems that adapt without full retraining (e.g., learn new rejection patterns from calls).

Implement lightweight local models to enable real-time learning on the edge.

Key Decisions / Dimensions
Platform Design & Delivery, Model Selection, Customization (if any) & Testing:

Choosing the right model for various task and actions.

Selecting appropriate model so that tasks can complete in efficient manner.

Defining reusable components in the platform. Delivery using configuration approach should be first preference, in case that does not work should go for customization.

Defining configuration parameters and incorporate them as platform design.

Testing and end to end testing of the project deliverable.

Load balancing between different models.

Always have switch on/switch off feature.

Must have all services backed up on primary/HA & DR servers.
Prompt Engineering:

Prompt Design & Development: Crafting prompts that guide AI systems to produce desired outputs for various applications, such as text generation, translation, question answering, and creative writing.

Testing and Evaluation: Analysing the effectiveness of prompts and refining them based on results to ensure accurate and relevant responses.

Bias Mitigation: Designing prompts that minimize bias and ensure fair and equitable outcomes from AI systems.

Major Challenges

Support from other platform owners

Building a Conversational Text AI BOT that doesn't just answer but negotiates with human-like reasoning.

Running large AI models in low-latency, low-bandwidth environments without cloud dependency.

Getting the end-to-end domain knowledge

Managing data and information security of the application.
