Who I Am
About Me
Bridging software engineering, cloud data infrastructure, and intelligent AI systems.
I'm a Software Engineer with 1 year and 7 months of experience architecting AI-driven Retrieval-Augmented Generation (RAG) pipelines using LangGraph to orchestrate generative AI workflows with Azure Cognitive Search and OpenAI.
I am adept at metadata enrichment, enterprise PII anonymization, and real-time SEO anomaly detection using PySpark, BigQuery, and GenAI. Guided by cloud best practices, I build robust, automated systems to deliver business intelligence and high-performance workflows.

Work Experience
Software Engineer
- Architected and deployed a Retrieval-Augmented Generation (RAG) solution on Azure, leveraging Azure Cognitive Search and Azure OpenAI for document ingestion and semantic retrieval.
- Implemented Python pipelines for enterprise-grade PII anonymization and metadata enrichment using SpaCy NER and Faker.
- Developed and maintained Azure Functions and Cognitive Search indexes to automate JSON processing and enable semantic search.
- Built a real-time SEO anomaly detection framework with PySpark, BigQuery, and generative AI — slashing recovery time from one week to three hours (~90% reduction).
Software Engineer Intern
- Automated Avionics Test-bed precision using Python; optimized projectile testing and developed embedded applications on ZynqSoC.
- Worked on Model-Based Software Development with Altair Embed; static/dynamic analysis of legacy code for MISRA standards using LDRA Tool.
- Implemented and tested MIL-STD 1553 communication protocol on ARM-I.MX8, Zynq Ultra-Scale, and MIL-STD 1553 interface boards.
Technical Trainee – Data Insights
- Trained and optimized ML classification models on GCP using large-scale datasets (Natality).
- Created secure and scalable VPC architectures and managed access privileges on GCP.
- Wrote optimized SQL analytics scripts in BigQuery to generate data intelligence dashboards.
