Experience
A Reporting Solution
Built a solution that is capable of handling massive traffic sent by different firewalls. The product stores all this data and provides search capabilities by firing any complex query on the data source, and the results appear in a few seconds. The product extends to any extent due to microservices architecture and the scalable data source that can scale horizontally and vertically.
Intelligent Stock Market Analysis Using Agentic AI
Developed an advanced agentic workflow for stock market analysis that orchestrates multiple specialized agents, each responsible for distinct tasks and recommendation generation. These agents collaborate by interacting with multiple large language models (LLMs), enabling more robust, cross-validated insights rather than relying on a single model.
It incorporates MCP servers to handle communication, tool execution, and data exchange between agents, ensuring a scalable and well-coordinated system. Overall, the solution automates end-to-end stock analysis—from input query to actionable recommendations—while maintaining flexibility and reliability through distributed intelligence.

A Wallet Application for a Financial Institute
The digital wallet is a digital version of your physical wallet. It allows you to perform all the transactions digitally when paying to the receiver's bank account or another digital wallet. In this project, I served as a tech lead, giving technical direction to the team and writing down the system's critical components.
