Abhishek Sharma

Technology Lead  ·  Chicago, IL

I'm a Technology Lead based in Chicago with 8+ 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.

My Career

Infosys Limited

Technology Lead — Chicago, IL
Leading a cross-functional team of 10–12 engineers in developing an enterprise contact center platform enabling airline reservation agents to book, modify, and manage passenger itineraries at scale. Architect microservices using .NET Core 8.0 with clean architecture and SOLID principles. Integrated Dynatrace for distributed tracing, reducing MTTR by ~67% (from ~1 hour to under 20 minutes). Championed TDD using XUnit/NUnit, achieving >80% code coverage. Designed and configured Harness CI/CD pipelines with automated quality gates via SonarQube & Veracode, enabling zero-downtime deployments across all environments.
