💼 Experience

SDE Intern · AlgoUniversity (YC S21)

May 2025 – Jul 2025 · Hyderabad

  • Built and deployed a cloud-native Online Judge on Kubernetes serving 50+ daily active users
  • Designed Redis Streams distributed eval pipeline decoupling submission intake from sandboxed workers → 5× throughput over sequential baseline
  • Engineered Docker sandboxing with cgroups + SECCOMP per submission
  • Implemented JWT + OAuth 2.0 + RBAC auth layer
  • Automated CI/CD enabling zero-downtime releases on AWS

📊 McKinsey Forward Leadership Fellow

Aug 2025 – Present · Remote

  • Structured analytical pipelines using MECE + hypothesis-driven frameworks
  • Built dashboards and automation workflows in Python + BI tooling
  • Applied decision decomposition to ambiguous, high-stakes engineering scenarios

🌐 Open Source · CNCF Contributions

Merged code running in production systems across thousands of cloud-native deployments globally.

   

Project PR Impact
OpenTelemetry #46506 AST constant folding for pure OTTL functions — parse-time compiler optimization, eliminates redundant per-datapoint evaluation in collector hot path. Accepted by OTel maintainers.
Kubernetes #137398 Goroutine hot-loop fix merged into K8s v1.36 in client-go StartEventWatcher. Reviewed and merged by senior K8s maintainers.
Kubernetes #137999 Fixed kubelet cgroup resize nil-pointer panic. Merged by K8s maintainers.
Jaeger multiple MaxTraceSize safeguard (OOM prevention on large trace queries) · API v3 limit/attribute filtering · OTTL delete matching values — all with full unit test coverage, merged to main.

GSoC 2026 · Proposed across 3 CNCF orgs: Jaeger AI Skills Framework · Kubeflow OTel Integration · Meshery AI Adapter — spanning Go compiler internals, Python SDK observability, and LLM agent interfaces.

🎓 B.Tech Thesis — Research

UAV-Assisted Obstacle-Aware Data Collection for Resource-Constrained IoT Networks
Supervisor: Dr. Ankur Jaiswal, ABV-IIITM Gwalior
Python · NumPy · D3QN · PPO · Visibility Graph

  • Modelled 800×600 m IoT deployment — 20 nodes, 3 cuboid obstacles (heights 128–148 m > UAV altitude 100 m)
  • Greedy dominating-set rendezvous selection achieves 65% node compression (20 → 7 stops, 100% coverage)
  • Visibility-graph routing produces collision-free paths (~2566 m, 9.2% battery)
  • Formulating D3QN agent for adaptive obstacle-aware path optimisation — state encodes UAV pose, residual energy, obstacle proximity, RP visit vector; reward jointly optimises data-priority collection, collision penalty, and energy cost
  • Exploring PPO as continuous-action extension
