I'm Robin Mollah, a Software Engineer with 12+ years of experience building systems that have to work beyond the happy path.

My work sits at the intersection of software architecture, AI, data engineering, cloud infrastructure, and automation.

I primarily work with Python, FastAPI, Flutter, Android development, AWS, GCP, data pipelines, AI systems, React, with a particular interest in building efficient, scalable solutions that minimize token usage, latency, infrastructure cost, and unnecessary complexity.

Over the years, I've worked on systems ranging from:

• ingesting millions of social-media messages per hour
• processing and analyzing terabytes of data without losing track of records
• real-time WebRTC streaming platforms
• SaaS and automation systems
• mobile applications
• customized operating systems for Wi-Fi router hardware

I enjoy problems involving scale, unusual constraints, difficult debugging, and unfamiliar systems.

Build it simply. Make it efficient. Understand how it actually works.

• NodeJS in Ubuntu, Cloud functions, Lambda and AppEngine
• ReactJS deployed in CloudFront, S3, Nginx’ed Linux server
• Linting, ensuring coding practices, scalability from dev and prod perspective
• Improving asynchronous workflow of developers
• CI/CD
• Managing cloud infrastructure of Video and Event Streaming Service
• Cost-efficient solution for graphics-heavy computation
• Ensuring the availability of network sensitive and mission-critical services worldwide

Our team developed a complex system to share unused WiFi bandwidth. I was responsible for:

• Developing complex networking-related systems like several microservices running in machines with no static IP.
• Developing the UI in React,
• Writing React Native Modules in Kotlin
• Developing Android apps in React Native
• Customizing router Linux OS,
• Making systems to control WiFi sharing This company gave me an opportunity to gain experience in a wider range.

• Managing large cloud infrastructure in AWS, Azure
• Optimizing networking between services
• Maintaining code repository
• Managing microservices and their interactions
• Attending meetings with different companies for requirement analysis and ensuring that the requirements can be met in all desktop computes, Android and iOs Devices.
• Containerising different services
