Kishlay Bhagwan

I am a highly skilled Senior Software Engineer with 6.5+ years of experience building scalable, secure, and high-availability distributed systems across Banking, Logistics, and Payments domains. I specialize in backend engineering using .NET / C#, Microservices, SQL Server, and event-driven platforms powered by Apache Kafka and Pulsar, delivering enterprise-grade solutions with strong performance, reliability, and modularity.

My expertise includes designing microservice-based architectures, developing RESTful APIs, and optimizing transactional data pipelines to support high-volume, real-time business flows. I have successfully led the engineering and enhancement of systems such as digital wallets, gift cards, incentive platforms, and logistics automation, driving measurable outcomes—including reduced latency, improved scalability, and increased user adoption.

I excel at performance tuning, including advanced SQL optimization, schema design, indexing strategies, and distributed streaming system improvements. I architect and implement clean, maintainable services and integrations that serve mission-critical processes with 99.99% uptime.

A proactive collaborator and mentor, I guide teams through technical decision-making, code reviews, and design best practices. I enjoy solving complex distributed-system challenges, fostering engineering excellence, and contributing to high-impact product strategies.

With a strong foundation in enterprise software engineering, domain-driven design, and event-driven architecture, I bring a deep focus on quality, reliability, and business alignment—consistently delivering solutions that enhance operational efficiency and customer experience at scale.
