Bijay Sharma

I’m a Backend Software Engineer with 3+ years of experience building backend systems and RESTful APIs using Python, FastAPI, Node.js, and AWS. I specialize in scalable SaaS backends, where I focus on serverless architecture, asynchronous processing, and secure authentication with JWT-based authorization.

At Appycodes Technologies LLP, I’ve built and deployed serverless backend services on AWS with Lambda, API Gateway, DynamoDB, SQS, and EventBridge, maintaining 300+ RESTful APIs for multi-tenant SaaS applications. I reduced API response time by 40% through Python-based caching, improved database performance by reducing load by 60% via query optimization and lazy loading, and accelerated long-running workflows by adding asynchronous processing to cut request delays by 20%. I also design practical ETL pipelines using PyMuPDF and Tesseract OCR to extract structured data from PDFs and scanned documents, and I integrate services like Stripe, MSG91, and third-party analytics to measure outcomes. I’m energized by clean microservices, SOLID principles, RBAC, and working closely with product, frontend, and QA teams to deliver reliable features on schedule.
