Abhishek Sharma

Technology Lead  ·  Chicago, IL

I'm a Technology Lead based in Chicago with 7+ years of experience designing and delivering backend systems that enterprise applications depend on. My expertise is in ASP.NET Core and AWS — building APIs that are clean and reliable, and cloud infrastructure that's built to last.

I specialize in backend engineering and cloud architecture — from high-throughput REST APIs and serverless workflows on AWS Lambda, to database design and zero-downtime migrations. I take end-to-end ownership of the systems I build, from architecture decisions to production reliability.

As a lead, I believe the best outcomes come from understanding the problem deeply before jumping to solutions. I work closely with business stakeholders to align on requirements, foster a culture of trust and accountability within my team, and make sure what we ship actually moves the needle.

Microservices

Clean architecture, SOLID principles, and event-driven design at enterprise scale.

AWS Cloud

Lambda, DynamoDB, SNS/SQS, Kubernetes — cloud-native from day one.

Team Lead

Cross-functional teams, sprint planning, mentorship, and end-to-end release ownership.

Observability

Dynatrace, DataDog, Kibana — zero-surprise production environments.
