About
I am a software developer with experience spanning from 2019 to the present, currently working as a Full-Stack Developer at NeovoTech Limited. Over these years, I have developed expertise in backend and full-stack development, cybersecurity training, and data science, working with companies in Bangladesh and remotely for Swedish firms.
My work spans technologies such as Node.js, OAuth, RSA encryption, Redis caching, and microservices architectures. I have built CI/CD pipelines using GitHub Actions and Jenkins, developed integrated trading systems with GraphQL and AWS Lambda, and delivered cybersecurity training on CEH and CompTIA Security+. I also work extensively with Python, TypeScript, JavaScript, and cloud platforms including AWS Amplify and Lambda.
