About Romharshan
I am a Senior Solution Architect and Full Stack Technology Leader with 20+ years of experience designing and delivering enterprise-scale digital platforms across Automotive AI, Yard Management, Smart Mobility, Healthcare, BFSI, FinTech, Procurement, Travel, Media and EV Charging.
My work spans architecture and hands-on engineering: HLD/LLD, APIs, microservices, event-driven systems, Kafka, cloud, Kubernetes, databases, observability, AI/RAG and modern frontend platforms. I stay close to implementation because architecture is strongest when it remains connected to code, deployment, failure modes and real production constraints.
Today my focus is on scalable AI-enabled platforms, distributed systems, cloud-native delivery and mentoring engineers who want to grow into stronger technical leaders and architects.
Technical Leadership & Platform Delivery
Led media, healthcare, banking CRM, communications, mobile and enterprise delivery teams while expanding into Node.js, Angular, MongoDB, real-time communications and architecture.
Solution Architecture Across Enterprise Domains
Architected platforms across BFSI, FinTech, procurement, retail data, travel, cloud and AI, with strong focus on microservices, Kafka, API architecture, modernization and engineering governance.
Senior Solution Architect – AI, Streaming & Smart Mobility
Leading architecture for an AI-powered enterprise yard-management platform that combines computer vision, radar fusion, Kafka, geospatial data, Kubernetes and real-time operational monitoring.
How I work
- Own high-level and low-level architecture, API contracts, sequence/ER diagrams and non-functional requirements.
- Design for latency, availability, security, cost, RTO/RPO, resilience and operational support.
- Lead architecture reviews, coding standards, POCs, performance tuning and production-readiness decisions.
- Mentor engineers and technical leads on system design, cloud, microservices, AI and full-stack engineering.
- Work across stakeholders, vendors and delivery teams while balancing architecture quality with delivery constraints.
- Stay hands-on with implementation, debugging, deployment and observability rather than treating architecture as diagrams only.
