Me, Md Zobayer Hossain Mamun
Software engineer with 8+ years of experience building secure, scalable web applications and cloud infrastructure — helping businesses ship fast and stay protected.
I'm a software engineer with over 8 years of hands-on experience in full-stack web development, DevOps, and application security. Since 2017, I've helped businesses — from early-stage startups to established enterprises — build digital products that are performant, reliable, and secure by design.
My work spans the full product lifecycle: architecting modern web applications with React and Next.js, setting up cloud infrastructure and CI/CD pipelines with Docker, Kubernetes, and AWS, and hardening applications with thorough security audits and penetration testing.
I bring a security-first mindset to every project — I build it, ship it, and secure it — ensuring the solutions I deliver are not just functional but resilient against real-world threats.

My core expertise
Specialized in web development, desktop software, and cybersecurity
Full-Stack Web Development
End-to-end web application development — from responsive, accessible frontends to robust backend APIs. I build modern web apps that perform at scale with clean architecture and best practices.
Backend Development
Scalable backend systems with clean architecture. Database design, API development, authentication, and server-side logic that powers your applications reliably under heavy load.
Microservices Architecture
Designing and building distributed systems with microservices. Event-driven architecture, inter-service communication, and independent deployability for complex, large-scale applications.
Third-Party & AI Integrations
Connecting your application to the services it needs — payment gateways, AI models, messaging platforms, analytics, and more. I handle the full integration lifecycle from auth to error handling.
DevOps & CI/CD
Automating your development workflow from commit to production. I set up containerized environments, build reliable pipelines, and ensure your team ships fast with confidence.
Cloud & Deployment
Getting your application live and keeping it running. Server setup, domain configuration, SSL, scaling, and monitoring — everything needed for a production-grade deployment.
Application Security
Building security into your applications from day one. I review code, harden authentication flows, secure APIs, and ensure your app follows industry best practices to prevent real-world attacks.
Security Auditing & Penetration Testing
Finding vulnerabilities before attackers do. I conduct thorough security assessments, simulate real-world attacks, and deliver actionable reports with clear remediation steps.
From idea to production
A structured, transparent process that keeps you in the loop at every stage
Discovery Call
I begin by learning about your business, your goals, and what you're looking to build. This helps me define a clear scope and set the right expectations.
Planning & Strategy
I choose the right technology, outline the architecture, and create a detailed roadmap — so you know exactly what to expect before work begins.
Design & Review
I prepare the layouts, structure, and key workflows for your project. You review and approve the direction before I move into development.
Development & Updates
I build in focused phases and share progress regularly. You stay informed throughout, and any adjustments are made early — not at the end.
Testing & Security
I run thorough tests to ensure everything works reliably. Security is built into my process from the start, not treated as an afterthought.
Launch & Ongoing Support
I handle the deployment and make sure everything runs smoothly. After launch, I remain available for any updates, fixes, or improvements you need.
