About Me

  • Full Name:Dilip Kumar Sharma
  • Location:Pune, Maharashtra, India
  • Experience:14+ Years

Sr Technical Lead with 14+ years of experience building and scaling backend systems across fast-paced environments.

My core expertise lies in Python-based microservices, system design (HLD/LLD), Docker, Kubernetes, and observability with OpenTelemetry, Prometheus, and Grafana.

Currently building a suite of open-source tools: an observability platform (OAAS), a JWT auth service, an e-commerce microservices platform, and supporting libraries — all production-ready with Docker, Kubernetes, FastAPI, Observability, authentication, authorisation.

Area Of Expertise

Backend Development

Building high-performance REST APIs and microservices with Python, FastAPI, Flask, and Django. Proficient in async programming, SQLAlchemy ORM, and clean architecture patterns.

System Architecture

Designing scalable microservices architectures with HLD/LLD, API contracts, repository pattern, and service-to-service communication. Zero-trust auth and event-driven design.

DevOps & Cloud

Containerized deployments with Docker, Kubernetes, and Helm. CI/CD pipelines on AWS and Azure. Infrastructure automation with Rancher across Dev, QA, Stage, and Production.

Observability

Built a full observability platform (OAAS) with OpenTelemetry, Grafana, Prometheus, Loki, Tempo, and Jaeger. Dashboards, alerting, and distributed tracing for production systems.

Team Leadership

Led teams of up to 6 engineers across product delivery cycles. Sprint planning in Jira, mentoring junior developers, cross-team coordination, and 95% sprint velocity.

Testing & Quality

Pytest, GoogleTest, 95% code coverage. Smoke, unit, and integration test strategies. JMeter for performance tuning. 20% reduction in post-release production defects.
