Work Experience

Software Engineer

Insurance Claim Intelligence Platform (ICIP)

Sep 2025 - Present

Engineered and enhanced AI-powered insurance claim processing workflows using FastAPI, automating claim intake, document verification, and settlement processes to improve operational efficiency. Architected a Hybrid RAG pipeline using Qdrant, Elasticsearch, and LLMs to enable accurate policy retrieval and context-aware claim analysis. Constructed and integrated RESTful APIs, asynchronous background tasks with Celery and Redis, and event-driven communication using Kafka for scalable and reliable processing. Applied JWT authentication, Role-Based Access Control (RBAC), and audit logging to ensure secure access, data integrity, and compliance with business requirements. Partnered with cross-functional teams to integrate OCR services, AWS Bedrock, and third-party APIs, delivering intelligent automation and improving the overall user experience.

Uniq Technologies

May 2024 - Present

Developed scalable web applications and RESTful APIs using Python, FastAPI, Django, and React.js, supporting 50+ concurrent users across multiple enterprise modules. Built AI-powered insurance claim workflows by integrating LLMs, Hybrid RAG, OCR, and AWS Bedrock, reducing manual claim review time by 35%. Orchestrated asynchronous processing pipelines using Celery, Redis, and Kafka, increasing background task throughput by 40% and cutting processing latency by 30%. Established JWT authentication, RBAC, audit logging, and secure REST APIs, maintaining zero critical security incidents across enterprise applications. Streamlined PostgreSQL/MySQL databases through indexing, query tuning, and Redis caching, cutting average query response time by 45%. Collaborated in Agile teams, integrating third-party systems and deploying applications using Docker, AWS, and CI/CD, accelerating release cycles by 25%.

Software Engineer

Plant Data Management System

Mar 2025 - Aug 2025

Designed and refined PostgreSQL database schemas with indexing, foreign key constraints, and materialized views to ensure data integrity and performance. Automated background task execution by integrating Celery with Redis (report generation, scheduled anomaly scans). Configured JWT-based RBAC middleware for secure API access, role validation, and shift-based permissions. Delivered RESTful APIs using FastAPI for modules including Production, QC, Inventory Management, and Anomaly Detection. Key Achievements: Reduced manual report generation time by 80% through automated Celery-based workflows; enhanced data retrieval performance by 40% using fine-tuned indexing and caching; supported regulatory compliance and audit readiness with complete traceability; contributed to the digital transformation of a traditional manufacturing plant.

Software Engineer

Supply Chain Transparency & Compliance Platform (ChainGuard)

May 2023 - Feb 2025

Launched a scalable supply chain transparency and compliance platform using FastAPI & Flask to provide real-time visibility across suppliers and manufacturers. Created high-performance RESTful APIs for supplier management, compliance tracking, risk assessment, and performance monitoring using FastAPI (async) and Flask. Enforced secure authentication and authorization using JWT and Role-Based Access Control (RBAC) to protect sensitive supply chain data. Integrated environmental impact tracking (carbon footprint, energy usage, waste metrics) to support sustainability and ESG reporting. Structured a robust and scalable backend architecture leveraging FastAPI async capabilities with PostgreSQL and SQLAlchemy ORM for high performance and concurrency. Deployed and managed the application on AWS (EC2, S3, RDS), ensuring scalability, high availability, and secure cloud infrastructure. Enabled API validation, exception handling, and interactive API documentation using Swagger/OpenAPI (FastAPI auto-docs).
