Md. Shaiful I.

I’m a Senior Java/Spring Boot Engineer and Software Architect with 15+ years of experience building, modernizing, and supporting SaaS and enterprise applications. I help businesses design scalable systems, solve complex technical problems, integrate AI capabilities, and improve existing applications without unnecessary rewrites. My core expertise includes: Java & Spring Boot — backend architecture, REST APIs, microservices, performance optimization SaaS Architecture — designing scalable and maintainable business applications AI Integration — integrating LLMs, AI-powered features, automation, and intelligent workflows into existing applications Cloud & DevOps — AWS, GCP, Kubernetes, Terraform/Ansible, CI/CD Databases — PostgreSQL, MySQL, Oracle, Aurora Full-Stack Development — React, Angular, PHP/Laravel, Node.js Legacy Modernization — improving architecture, performance, maintainability, and reliability of existing systems Technical Leadership — system design, estimation, technical planning, project delivery, and engineering governance Recent Product & Architecture Experience I don't only develop software for clients — I also design, build, and operate my own products, which gives me practical experience across the entire product lifecycle. FlyerImage — a WordPress campaign/visual builder plugin featuring a drag-and-drop canvas, campaign scheduling, targeting, templates, and analytics. FlyerMoney — a personal finance Android application focused on expense tracking, spending categorization, financial insights, and AI-assisted features. PMO Nexus — a project governance and management platform designed around project health, delivery tracking, estimation, risk, quality, resource, and financial/margin management. These projects have given me hands-on experience not only with development, but also with product decisions, architecture, UX, deployment, monitoring, maintenance, and real-world user requirements.
