Rupraj Datta

Software & Systems Engineer • Application Security & Distributed Infrastructure
B.Tech in Computer Science & Engineering — Bennett University (Noida, India)

Available for Hire LinkedIn Email X

🎯 Executive Objective: Actively seeking Software Engineering Internships and Early Career Systems / Backend / AppSec Roles (2026/2027). Focused on high-concurrency architectures, network packet inspection (DPI), OWASP API security hardening, and resilient distributed protocols. Open to on-site, hybrid, or remote opportunities globally.

🌐 Open-Source Upstream Contributions

Contributions successfully merged into external open-source projects:

  • calibrain/shelfmark #1632 Merged
    High-Throughput Spooled Disk Buffering: Re-engineered memory buffering for heavy debrid streaming pipelines using disk-backed spooled temporary file buffers, eliminating out-of-memory crashes on resource-constrained servers. Collaborated with upstream maintainers on stream cancellation disposal and regression tests. Merged into upstream master.

  • nikhilrai-tech/Nigrani #45 Merged
    Fractional Telemetry & Metric Scaling Engine: Implemented dynamic ratio unit scaling (unit: ratio) for system metrics, unified telemetry chart scaling, and authored full frontend/backend regression suites with all 230 tests passing. Merged into upstream main.

  • nikhilrai-tech/Nigrani #73 — Co-authored a merged change that labels New Relic alerts using FACET attribute names; the maintainer incorporated the idea from PR #69.

  • AaronCreor/PyFuncAI #6 Merged
    Structured Cache Metadata Validation: Implemented structured JSON metadata extraction and validation for offline AI caching environments, backed by comprehensive unit test coverage. Merged into upstream master.
