Sanjeev Kumar — Application Architect

Professional Profile

Sanjeev Kumar is an Application Architect based in Delhi-NCR, India, currently Technical Architect at Wipro Limited. He designs and delivers distributed, cloud-native enterprise software — with particular depth in Java, Spring Boot, microservices, Apache Kafka, Kubernetes, and platforms on GCP and AWS.

His work focuses on regulated domains where correctness and auditability matter: banking and financial services, healthcare and insurance. He authors HLD/LLD and architecture decision records, sets engineering standards for delivery squads, and has led teams of up to 18 engineers while remaining hands-on in design and code review.

In 2024 he completed eMasters — Artificial Intelligence & Machine Learning at Indian Institute of Technology (IIT) Kanpur, and applies that foundation to enterprise retrieval-augmented generation and agentic tooling grounded in real architecture corpora — without treating a model as an authority over system design.

Contextual titles that describe the same practice include Technical Architect, Solution Architect, Java Architect, Cloud Architect, AI Solution Architect. Primary identity remains Application Architect.

Architecture Expertise

Day-to-day work spans end-to-end application architecture: API-first and event-driven design, strangler-fig modernisation of legacy platforms, cloud networking and platform controls, and observability treated as part of the architecture rather than an afterthought.
