@Concentric AISoftware Engineer (Jul. 2026 – Present) | Software Engineer Intern (Jan. 2026 – Jul. 2026)

Bengaluru, India

•Owned DelcoSpark, an org-wide deletion engine (Java, Spark, Kafka, Argo Workflows) sustaining 15.3M+ deletes/hr (∼4,200/sec) on Hudi tables in AWS S3; stopped cascading deletion loops across Lakehouse dependency DAGs via 3-color DFS cycle detection.

•Architected an extensible batch framework adopted by 2+ services using Strategy, Factory, and Builder patterns; incremental Hudi ingestion with commit throttling and checkpoint resumption prevents executor OOM failures across massive datasets.

•Eliminated double status updates and audit drift by designing an eventually consistent audit model where MongoDB checkpoint replay converges state from the last successful checkpoint after Spark retries.

•Eliminated data anomalies across DSPM pipelines by resolving silver-layer Spark ETL issues, strengthening reliability for enterprise file archival, retention rules, and Microsoft 365 Copilot events.

•Deployed Spark operator workloads on Kubernetes via Helm-rendered Argo WorkflowTemplates and 3-hourly CronWorkflows; added frozen-IO tests to Jenkins CI/CD sanity suite.

@GoQuant Technologies IncBackend Engineer Intern (May 2025 – Sep. 2025)

Florida, USA (Remote)

•Unified real-time market data feeds from 3+ crypto exchanges (KuCoin, Hyperliquid, Bybit) by building OEMS connectors in Python, FastAPI, and PostgreSQL feeding a low-latency C++ ingestion layer.

•Opened institutional access to 2 FIX-only venues (PowerTrade, Wintermute) restricted in select regions by designing a QuickFIX proxy gateway with secure tunneling and JWT authentication inside the OEMS.

•Delivered sub-millisecond market-data updates and under 200 ms execution latency in a multi-threaded C++ trading engine prototype over WebSockets, using lock-efficient O(1) order book structures.

•Cut benchmark configuration load to under 10 ms and updates to under 20 ms by tuning cache-aligned C++ data structures, move semantics, and memory access patterns, guided by microsecond-level profiling.

@Ahmedabad UniversityTeaching Assistant (Jan. 2025 – Nov. 2025)

Ahmedabad, India

•Mentored 120+ students in Data Structures & Algorithms (C++, Java, Python) and 80+ students in Applied Linear Algebra; scaled on-premise DSA platform to support concurrent code execution for 120+ students by containerizing runtimes with Docker.

Competitive Programming Lead (Apr. 2024 – May 2025)

•Automated live leaderboard scoring for 130+ contest participants by building real-time pipelines from the Codeforces API to Google Sheets while leading a 20+ member committee.

Open Source Contributions

•@Omalt-Tab (Hyprland / Wayland task switcher on Omarchy Marketplace, 300+ users, 23+ stars, sub-ms UNIX socket IPC, security fix for plain text rendering)
