Beyond the Resume

I enjoy building systems that turn messy real world problems into reliable software.

My background sits between backend engineering, data systems, and AI applications. I've spent my career writing production code whether that's ingesting data at scale, building structured APIs, or integrating models that get deployed.

At Accenture, I worked on enterprise scale data workflows where reliability, validation, debugging, and production support mattered every day. That experience taught me how important clean architecture and resilient systems are at scale.

At UB's A2IL Lab, I'm building Spring Boot APIs and backend workflows for a faculty management platform focusing on maintainable backend design, structured APIs, and relational data systems.

I enjoy taking ambiguous problems, breaking them into smaller backend components, and building systems that are easy to reason about, test, and ship.

Where I've Worked

Software Engineer Intern

University at Buffalo — A2IL Research Lab

Feb 2026 – Present Buffalo, NY
  • Built Spring Boot REST APIs for a centralized faculty management platform, using a layered architecture (Controller → Service → Repository) to support 100+ users across academic workflows.
  • Designed DTOs and JPA projections to efficiently map complex query results, reducing unnecessary entity loading and improving response performance.
  • Implemented a cross-database SQL join across multiple MySQL schemas for committee membership retrieval, enabling relational data access across system boundaries.
  • Documented all APIs using Swagger/OpenAPI and resolved production schema mismatches, improving team DX and system reliability.

Software Engineer — Backend & Data Systems

Accenture

Aug 2022 – Aug 2024 India
  • Built distributed ingestion workflows on GCP, orchestrating data pipelines across SharePoint, SFTP, GCS, and BigQuery — processing 100K+ records per file across daily high-volume loads.
  • Designed a modular, multi-stage pipeline architecture (extraction → staging → warehouse) with reusable validation and transformation components, improving maintainability and debuggability.
  • Improved SQL query performance by 20–25% through indexing, optimization, and schema tuning across large-scale enterprise datasets.
  • Automated CI/CD deployments across Dev, QA, and Production environments and resolved production incidents through structured root cause analysis.
