Skill set
Ajay in a few words
I’m a UK-based freelance software engineer specialising in cloud migration, DevOps, and full-stack development. With hands-on experience moving 30+ applications from AWS to Azure using Docker and Blob Storage, I help businesses reduce cloud costs, improve reliability, and modernise their infrastructure.
My recent work includes building high-performance web apps using React, Next.js, Django, and TypeScript, implementing CI/CD pipelines that reduced deployment time by 60%. I’ve architected over 50 RESTful APIs with Swagger documentation and optimised systems for speed and security—boosting server performance by 55% and cutting database load by 65% with effective caching strategies.
From analytics platforms with real-time monitoring to containerised development environments, I’ve delivered results for startups and scale-ups alike. I’ve also resolved 100+ critical production bugs, significantly reducing customer-impacting incidents.
If you’re looking to migrate to Azure, containerise your stack, improve deployment workflows, or build scalable web applications, I can help deliver outcomes—not just code.
Available for freelance projects, fixed-scope packages, or UK-based contract roles (remote/hybrid).
