About

Professional summary

I am a Senior Software Engineer and Forward Deployed Engineer with six years of experience building enterprise AI applications, distributed backend systems, and cloud platforms. I have delivered solutions for Oracle, PayPal engagements, ByteDance, Dunzo, BMW, and startup environments.

I specialize in Golang and Python development, system design, microservices, cloud-native infrastructure, and production API platforms. My work spans Kubernetes, AWS, GCP, Oracle Cloud, observability, security, reliability, and scalable data systems.

I have hands-on experience building RAG and agentic AI systems, including hybrid retrieval, vector search, reranking, LLM integrations, evaluation workflows, guardrails, authorization controls, and human-in-the-loop execution patterns. I focus on evidence-grounded, secure, and operationally reliable AI applications.

I enjoy translating complex product, platform, and infrastructure requirements into practical architectures and production-ready services. I have designed systems for GPU workload management, inference platforms, billing and quotas, data ingestion, enterprise integrations, and high-throughput APIs.

I bring a strong ownership mindset across architecture, implementation, observability, incident response, and end-to-end delivery. I am motivated by solving difficult engineering problems that improve scalability, cost efficiency, security, and developer or customer experience.

Career history

Senior Member of Technical Staff Oracle

Led data-quality initiatives for Oracle Asset Inventory across OCI services, using AI-assisted analysis to resolve critical inconsistencies and improve data reliability by 15%. Designed a database snapshot delta optimizer that reduced data redundancy by up to 99% and storage needs by approximately 90%.

Onboarded four enterprise datasets supporting real-time ingestion of roughly 10,000 change events per second through Apache Spark pipelines. Built a hybrid RAG system using vector search, PostgreSQL full-text search, reciprocal rank fusion, reranking, source citations, evaluation across 700+ benchmark questions, and retrieval-time authorization and lifecycle controls.

Senior Forward Deployed Engineer PayPal (via Gruve.ai)

Translated product, platform, and AI infrastructure needs into solution architectures, APIs, implementation plans, and production services covering inference, billing, access control, observability, and GPU infrastructure. Built an internal LLM-powered natural-language query dashboard using self-hosted Llama, DeepSeek, and Qwen models with fallback mechanisms.

Designed quotas and billing services for an Inference-as-a-Service platform, achieving a 99% payment success rate. Architected a Kubernetes GPU cluster manager for 40+ GPU nodes, improved utilization by 50% with NVIDIA MIG, delivered 15+ Golang APIs, and integrated RBAC across 30+ APIs. Also improved observability, reduced logging costs, and reduced eBPF ingestion latency from approximately 700 ms to 100 ms.

Member of Technical Staff Oracle (ByteDance)

Reduced compute costs by 30%, saving more than $100K per month while preserving 99.99998% availability-domain resiliency. Developed multi-region capacity-management and autoscaling strategies for major traffic events, including Black Friday and year-end demand.

Contributed to log compression and deduplication work that reduced storage by 40%, and created similarity detection across 500,000+ log records using cosine similarity and disjoint-set structures. Improved a Golang SDK, configuration injection, monitoring, and incident operations, adding 30+ metrics and alarms and handling Severity-1 and Severity-2 incidents.

Software Engineer Dunzo

Decomposed an overloaded Python monolith into two microservices, built a Golang service, and migrated more than 60 APIs while maintaining production functionality. Developed 25+ APIs for inventory, catalog, and order services and reduced API latency by 40% through database-query optimization.

Introduced Redis-based distributed locking for critical inventory workflows. Built a GCP Cloud Function for asynchronous CSV validation that processed 100K-row files in under one minute, and improved replenishment workflows to reduce related capital losses by approximately 20%.

System Engineer Tata Consultancy Services (BMW)

Architected asynchronous batching, upload, and download workflows for diagnostic data using AWS S3. Enabled 20 workers to process workloads concurrently.

Automated infrastructure health checks and operational tasks, improving engineering efficiency and saving the team more than 20 hours per week.

Software Engineer Intern SkilltoHire

Developed and maintained full-stack application features using Java, Spring Boot, React, and MySQL. Implemented REST APIs and responsive user interfaces for core product workflows.

Built user-management and application APIs with input validation, authentication, and database operations. Created reusable React components and integrated frontend workflows with backend services.
