I specialize in hands\-on backend and platform engineering, system design, and performance optimization for high\-throughput, highly reliable services\. My core expertise lies in Java, Spring Boot, AWS, microservices, and distributed systems, with strong experience building secure APIs, event\-driven architectures, and scalable backend platforms\. I have worked extensively on cloud\-native architectures, Infrastructure as Code, CI/CD pipelines, and containerized deployments using Docker, Kubernetes, EKS, OpenShift, and Helm\. I enjoy solving complex system\-level problems—from designing HLD/LLD and data flows to improving latency, reliability, and operational resilience in production systems\. I am comfortable working end\-to\-end: architecture, implementation, performance tuning, and production support\. My core expertise lies in: • Designing high\-throughput event\-driven systems \(Kafka, microservices\) • Building cloud\-native platforms on AWS \(ECS, Lambda, DynamoDB\) • Developing real\-time security detection pipelines • Scaling systems processing millions of events Recent work: • Architected a shared GenAI/LLM inference platform for email threat detection, consolidating model serving across the security org • Led root\-cause analysis and remediation for an ML detection service failure during a Kafka outage — fix shipped, failure\-mode analysis extended across the service • Cut AWS S3 cost on a high\-volume workload by 20% by re\-architecting write patterns • Built cross\-product threat\-intelligence signal sharing across email, endpoint, firewall, and XDR I’m particularly interested in: • AI\-powered security platforms • Large\-scale distributed systems • Real\-time data processing architectures Always open to discussing system design, AI in security, and platform engineering\. I am passionate about building simple, scalable, and resilient systems and continuously learning modern engineering practices\. Open to Principal / Staff Software Engineer \(IC\) opportunities focused on platform, backend, and distributed systems\. How I work: I go after the problems nobody owns — reliability gaps, cost blowouts, the architecture decision three teams are each half\-making\. Most of my impact lands through other teams' roadmaps, not my own commits\. ## Location Bengaluru ## AI stack claude code codex cursor github copilot Microsoft Copilot Synthesia ## Work experience Principal Engineer 1 at Sophos, Jan 2024 \- Present · 2 yrs 9 mos, Bengaluru, Karnataka, India, Own organization\-level architecture for email security processing and ML\-based threat detection\. \- Architect and implement secure, distributed backend systems processing millions of email transactions daily, with strong guarantees around availability, latency, and data integrity\. \- Building AI/LLM driven email security platform\. \- Drive design decisions for cloud\-native, event\-driven services using Java, Kafka, AWS, and microservices architecture\. \- Lead deep technical problem\-solving across scalability, performance, and resilience, including latency reduction and reliability improvements\. \- Define and evolve core architectural patterns, APIs, and best practices adopted across teams to improve long\-term maintainability and delivery speed\. \- Act as a technical anchor for complex initiatives, providing hands\-on guidance from design through production rollout and operations\. \- Identified and re\-architected S3 write patterns on a high\-volume workload, cutting PUT\-request spend by 20%\.
