SaaS Product Development
Multi-tenant products with plans, usage limits, billing concepts, admin dashboards, and background processing — from concept through implementation.
Hi, I am Mahfuz Sakib.
A Senior Full-Stack Developer & SaaS Builder based in Bangladesh.
I build scalable software products, SaaS platforms, and business applications that solve real-world problems.
Services
What I build
Software products and systems for companies, founders, and businesses that need something that actually ships.
Business Software
Invoice, due, inventory, sales, purchase, dealer, and customer systems designed around real operational workflows rather than generic CRUD screens.
Full-Stack Web Applications
Laravel backends, REST APIs, authentication, queues, and practical UIs that hold together as complete products — not disconnected features.
AI-Powered Solutions
Practical AI inside real software: transcription, analysis, automated QA, media pipelines, and usage-metered processing — not demo chat widgets.
Selected work
My recent works
Products and systems that show how business software, SaaS architecture, and AI pipelines come together.
