About Me

I am Faisal Mahamud, a Senior Full-Stack / Backend Engineer with 4+ years of experience designing and scaling SaaS platforms and distributed systems. I graduated from BGC Trust University with a B.Sc. in Computer Science & Engineering (CGPA: 3.86/4.00).

Currently working as Senior Full-Stack Engineer / DevOps at Agrigate Network Ltd, I lead development of scalable web applications for agricultural platforms serving real-time market prices, weather data, and AI-driven agent development. My expertise includes Node.js microservices, React, event-driven architectures (RabbitMQ), circuit breaker patterns, and cloud-native deployments on AWS.

I have successfully delivered production systems serving millions of users, including Muslim Bangla App, Melbourne Limolink, Science Master, Permisgo, and HIPAA-compliant healthcare platforms. My achievements include reducing AWS cloud costs by 40% through infrastructure right-sizing, reducing release time by 20% via automated CI/CD pipelines, and improving workflow efficiency by 20% through optimized backend features.

I am passionate about leveraging technology to solve real-world problems, particularly in scaling distributed systems and optimizing cloud infrastructure. I continuously strive to implement innovative solutions that drive business growth, improve system reliability, and enhance user experience.
