Bharat Khanna

• Technical leader driving architecture and strategy for large-scale, multi-tenant agentic AI platforms, enabling real-time decisioning and intelligent user experiences.
• Architected a low-latency, event-driven AI platform (streaming voice → transcription → agentic LLM orchestration → real-time UI) delivering sub-second latency at scale (300+ concurrent users) and measurable impact on conversion and cost efficiency.
• Designed a generalized agentic framework (LangGraph-based) for orchestration of reasoning, tools, and memory, enabling reusable, configurable AI capabilities across multiple products and accelerating development velocity.
• Led development of production-grade AI systems including real-time assistive intelligence, live data capture into CRM, and automated communication workflows with human-in-the-loop and compliance safeguards.
• Built and scaled distributed, fault-tolerant systems using event streaming (Kafka), microservices, and cloud-native infrastructure (GCP, Kubernetes), with strong focus on reliability, scalability, and latency optimization.
• Established LLM quality and observability practices (evaluation datasets, tracing, scorecards, regression testing) to ensure consistent, measurable system performance in production.
• Drive org-level technical strategy, influencing architecture and making critical trade-offs across latency, scalability, and cost in complex, ambiguous environments.
• Mentor senior engineers, lead design reviews and engineering standards, and elevate execution across teams.

Staff / Senior Staff Engineer — Distributed Systems & Cloud Platforms | American Express

• Led end-to-end ownership and delivery of critical platform features for the iScreen application, driving high-impact initiatives aligned with business and customer needs.
• Defined and evolved application and platform architecture, establishing scalable, resilient, and extensible designs for enterprise-grade systems.
• Partnered with business and senior stakeholders to identify opportunities, translate ambiguous requirements into well-defined technical solutions, and drive execution across teams.
• Architected and delivered cloud-native solutions on AWS (EC2, S3, RDS, DynamoDB, SQS, IAM, EMR), ensuring high availability, fault tolerance, and auto-scaling for distributed workloads.
• Led full software development lifecycle (SDLC) across multiple initiatives—design, prototyping, POCs, development, deployment, and production support—in an agile environment.
• Drove technical strategy and design decisions, introducing architectural improvements, integration patterns, and best practices to optimize system performance and scalability.
• Built and scaled non-production cloud environments (dev/test) to enable faster iteration, testing, and reliable releases.
• Mentored engineers and led team onboarding and capability building, enabling smooth transitions to new systems and improving overall team productivity.
• Established strong cross-functional collaboration across geographies, managing risks, dependencies, and execution to ensure timely and high-quality delivery.

QVC Group, Principal Technical Architect | May 2015 – August 2018

Directed the architecture and enterprise-scale execution of the Multi-Channel Asset Scheduling and Automation (MCASA) engine. Spearheaded the technological transition of a multi-billion-dollar live home shopping network into an automated, multi-platform video commerce ecosystem, serving as a cornerstone for QVC Group's strategic corporate turnaround.

• Enterprise Automation & Financial Impact: Architected the core automation infrastructure driving the "Project Athens" turnaround strategy, delivering the foundational technology that facilitated over $500 million in run-rate OIBDA savings.
• Real-Time Omnichannel Rules Engine: Authored standardized digital asset management (DAM) schemas linking live television broadcast graphics directly with real-time e-commerce databases. Implemented dynamic eligibility rules (e.g., live inventory depletion, flash pricing) to autonomously adjust in-flight programming without manual intervention.
• Next-Gen "Live2VOD" Orchestration: Engineered an automated workflow engine that dynamically segments continuous live home-shopping broadcasts into device-optimized, shoppable micro-clips, massively reducing the latency between live-air and digital point-of-sale.
• Global Platform Expansion: Built the core integration orchestration layer that scaled QVC’s distribution beyond traditional linear television onto high-margin digital frontiers, including OTT, VOD, QVC+, and mobile/tablet ecosystems.
• System Consolidation & Cost Optimization: Re-architected legacy workflows using Service-Oriented Architecture (SOA), successfully decommissioning multiple costly media vendors and drastically reducing enterprise software licensing and infrastructure overhead.
• Technical Leadership & Governance: Directed globally distributed engineering squads through the full Agile lifecycle. Established enterprise-wide development standards, rigorous code review protocols, and vulnerability elimination frameworks for high-availability systems processing live broadcast integrations.
