Experience

Highlights from my industry work across telecom systems and mobile platforms.

Senior Software Development Engineer - Nokia

Bangalore, India 路 March 2025 - Aug. 2025

  • Hardware Digital Twin (Golang): Engineered a high-fidelity simulation engine for CHM7 L1 hardware, mocking register maps and I2C bus interactions to create a virtual testbench.
  • Enabled firmware validation to begin about 3 months before silicon arrival, improving development predictability and reducing hardware dependency during early testing.

SDE 2 / Senior SDE - Infinera

Bangalore, India 路 Aug 2021 - Feb 2025

  • Distributed Simulation Farm: Architected a scalable internal cloud platform in Golang for parallel firmware testing, increasing test throughput by 3x and reducing regression feedback loops by 40%.
  • Active-Active Redundancy: Designed failover logic and implemented state synchronization in C++ to achieve sub-50ms failover and 99.999% availability for mission-critical optical chassis.
  • Cost Optimization: Engineered an encrypted management traffic feature on legacy hardware, avoiding mandatory hardware refresh and delivering over $2M in CapEx savings.

Software Engineer / Senior Engineer - Oppo Mobiles

Hyderabad, India 路 July 2019 - July 2021

  • Camera HAL Optimization: Led C++ backend optimization for Android Camera HAL and re-architected media data pipelines to reduce camera launch latency by about 200ms across 50M+ active devices.
  • Kernel and Framework Stability: Diagnosed and fixed race conditions and memory leaks in Android framework components, reducing pre-production system crash rate by 35%.

Key Projects

Large Language Model and Reasoning

Academic / Personal

Built a custom LLM with FlashAttention for faster forward passes and lower memory use, then added post-training alignment pipelines (SFT and GRPO) to improve reasoning quality.

Single-Cell Genomics AI Pipeline

NYU Courant

Developed an end-to-end scRNA-seq pipeline for integration and cell-type annotation using MLPs, autoencoders, and probabilistic models such as scVI and scANVI.
