Work Experience

Associate System Analyst

SmartRecon Technologies Pvt. Ltd.

Feb 2025 - Present

Improved batch job execution performance by ˜80% by implementing standardized batch I/O practices and leveraging advanced Spring Batch features previously unused. Designed and implemented fault-tolerant Spring Batch workflows with checkpointing and restartability, allowing jobs to resume from the last successful state instead of restarting from scratch, reducing operational downtime and reprocessing costs. Identified and resolved a subtle Spring Expression Language (SpEL) compilation issue involving logical operator short-circuiting; introduced optimized expression patterns, resulting in ˜90% faster expression execution. Designed and implemented fully streamed generation and download of large CSV, XLSX and PDF files, eliminating in-memory buffering and enabling file creation with billions of records using near-constant memory. Strengthened application security by remediating critical vulnerabilities, including SQL Injection, HTML Injection, IDOR, and misconfigurations in CORS and Content Security Policy (CSP). Fixed performance defects in a custom database log appender, reducing idle CPU utilization from ˜95% to near 0% on the logging thread. Identified, documented, and communicated implicit and opportunistic performance optimizations within the application, enabling users and teams to leverage the system’s full performance potential.

Unity Game Developer Intern

IDZ Digital Pvt. Ltd.

Oct 2023 - Jan 2024

Implemented an interactive drawing board with automatic smoothing of sharp corners and edges using B´ezier curve interpolation, producing visually continuous strokes while preserving user intent. Designed and optimized a rope-based physics simulation to model character hair, applying constraint relaxation and segment-based dynamics to achieve stable, natural motion with minimal computational overhead. Implemented gravity and acceleration-based motion for objects constrained to follow predefined tracks, accurately simulating kinematic behavior under continuous forces.
