• Architected and deployed real-time backend services processing high-frequency telemetry data across 10+ distributed subsystems, achieving 99.9% uptime in safety-critical defense deployments.
• Engineered high-performance, deterministic backend modules in C++ and C# on Linux and QNX RTOS, reducing average response latency by 40% through lock optimization and memory-efficient data structures.
• Designed fault-tolerant architectures with graceful degradation, watchdog-based auto-recovery, and health monitoring, eliminating single points of failure and reducing mean-time-to-recovery (MTTR) significantly.
• Built automated telemetry and diagnostics pipelines enabling real-time observability and reducing fault isolation time from hours to minutes across production environments.
• Optimized system throughput and concurrency using multithreading, lock-free patterns, and performance profiling, handling 10,000+ events/sec with sub-millisecond processing guarantees.
• Led design and code reviews across a team of 8+ engineers, enforcing best practices in API design, scalability, maintainability, and system evolution for long-term reliability.
• Collaborated with cross-functional stakeholders including system architects, domain experts, and QA to meet strict safety, reliability, and compliance requirements.

Software Engineer Intern (Backend) - Autolytics Pvt. Ltd. - Remote

(2021-04 - 2021-06)

• Developed and deployed a production-grade backend service for automated server command execution, monitoring, and alerting, reducing manual operational overhead.
• Designed RESTful APIs and observability features enabling rapid iteration, real-time fault diagnosis, and improved operational reliability for the infrastructure team.

Data Recovery Engineer - Sunrise Computer Centers - Gorakhpur, India

(2018-04 - 2019-05)

• Performed low-level diagnosis and recovery of corrupted storage media and file systems, building deep expertise in system internals and binary-level debugging.
• Owned end-to-end incident resolution, strengthening skills in root cause analysis, failure forensics, and structured troubleshooting under time-critical constraints.
