About Abhishek Sahu

With 9+ years of experience building scalable backend systems, I specialize in designing high-performance APIs and cloud-native, serverless architectures using Python, Django, AWS Lambda, API Gateway, Redshift, S3, Airflow, and CI/CD pipelines. I have hands-on experience optimizing high-concurrency workloads, reducing API latency by up to 90%, and building reliable, production-grade systems with strong observability and testing practices.Currently leading backend and test automation initiatives at Wipro (client: Abbott), where I’ve architected automation frameworks from scratch, improved automation coverage by 70%, and integrated CI/CD pipelines using Jenkins and Allure. I’ve also designed and optimized AWS Lambda-based microservices, implemented async background processing, and built robust data ingestion pipelines backed by Redshift and S3.Previously, I’ve built data pipelines, REST APIs, and cloud solutions for global enterprises such as Bombardier (via Randstad) and Shell (via RGP). My experience spans dynamic data processing on AWS (Lambda, API Gateway, RDS, S3), performance optimization for large-scale workloads, and deploying containerized services in cloud environments.Highlights- Built and scaled 100+ REST APIs using Python and Django REST Framework- Reduced API response times by ~90% and improved data processing performance by 50%+ through async processing and caching strategies- Implemented production-grade serverless systems on AWS (Lambda, API Gateway, Redshift, S3, Secrets Manager) with CI/CD automation-Achieved high reliability with automated testing (Pytest), structured logging, and monitoring across multiple projects.I’m passionate about building clean, scalable backend systems, automating workflows, and continuously improving system performance and reliability. Happy to connect for opportunities or collaborations in Python backend engineering, serverless/cloud architecture, and data platforms.

Experience

1. Development Team Lead

   Wipro

   Jun 2024 — Present · Noida, IN

   Led backend development for serverless microservices on AWS Lambda supporting high-throughput data ingestion and processing workflows- Designed asynchronous processing for bulk APIs, reducing response time by ~90%(10+ seconds to <3 seconds)- Refactored LOC Lambda codebase, centralizing SQL queries and improving maintainability- Built dual database access layer supporting Redshift Data API and psycopg2, enabling environment-based switching- Implemented async job tracking using S3-based state monitoring for real-time processing status- Built concurrent load-testing framework simulating 50 users, achieving ~492 records/sec throughput- Migrated DB connectivity from psycopg2 to Redshift Data API, cutting execution time by ~40%.
