Professional Experience

Sep 2024 – Present

AI Software Engineer

PNC Financial | United States

  • Engineered Java Spring Boot microservices for PNC's AI-assisted portfolio intelligence platform, supporting over 350 institutional portfolios and optimizing model-driven trade execution workflows through event-driven architecture and parallel processing pipelines
  • Developed React + Express-based analytics console with modular TypeScript components and API integrations, allowing investment strategists to visualize portfolio exposure, model drift, and rebalancing insights across multiple asset strategies
  • Integrated Python FastAPI services with LangChain and document-embedding pipelines to process 250K+ investment research files, enabling automated insight extraction and reducing manual analysis overhead by thousands of pages per quarter
  • Built scalable streaming infrastructure using Apache Kafka and Airflow to orchestrate real-time data ingestion from market feeds and internal trade systems, processing 4.2 TB of raw data each week for downstream AI pipelines
  • Collaborated with data science teams to fine-tune Transformer-based NLP models hosted on Hugging Face and deployed through AWS SageMaker, generating contextual summaries and cutting insight turnaround from 90 minutes to under 20
  • Implemented low-latency model-serving endpoints using Amazon DynamoDB and async I/O patterns, achieving sub-120 ms response times for predictive analytics APIs consumed by risk dashboards
  • Automated end-to-end build, validation, and deployment processes with Jenkins, Docker, and Kubernetes, maintaining continuous delivery pipelines for 30+ AI microservices hosted on AWS
Apr 2021 – Jul 2023

Software Engineer

Goldman Sachs | India

  • Constructed and deployed Java Spring Boot microservices for the internal trade settlement platform handling 1M+ daily transactions, improving throughput by restructuring message queues and optimizing serialization logic
  • Formed Angular-based dashboards using modular TypeScript components and RxJS data streams that provided real-time visibility into trade positions across 12 global trading desks, enhancing desk coordination and operational clarity
  • Established GraphQL APIs integrated with PostgreSQL and Redis caching layers, supporting high-frequency trade queries with a consistent 80-90 ms average latency during peak hours
  • Embedded AWS SageMaker models with Lambda for real-time trade anomaly detection, allowing risk teams to flag potential outliers 3× faster and significantly improving audit readiness
  • Designed and maintained Angular-Node.js-based internal tools for portfolio exposure reporting, improving collaboration between risk and compliance teams
  • Led migration of legacy MySQL databases to PostgreSQL, introducing partitioned tables and optimized indexing strategies that improved batch reconciliation stability across 14 systems
  • Set up Prometheus and Grafana stack to monitor service health and latency, enabling anomaly alerts and reducing on-call escalations
  • Executed centralized logging via the ELK stack (Elasticsearch, Logstash, Kibana), simplifying debugging for over 40 microservices and shortening incident analysis cycles
  • Streamlined CI/CD workflows using Jenkins, Docker, and Kubernetes, automating deployments and cutting build-to-release steps from 14 to 6
  • Partnered with the security engineering team to establish OAuth 2.0 and JWT-based authentication standards across all APIs, ensuring compliance with Goldman Sachs' internal security protocols

Featured Projects

CentrX - Student & Club Engagement Platform

Node.js MongoDB JavaScript Hugging Face LangChain SLU SSO

Architected and deployed RESTful APIs supporting over 2,000 student interactions per semester by enabling RSVP tracking, real-time updates, and personalized content recommendations using Hugging Face Transformer models. Incorporated SLU Single Sign-On with OAuth2/JWT and applied GPT-powered summarization via LangChain, generating automated event briefs and engagement insights that reduced manual reporting time by several hours weekly.
