Mohammad Zobair Hossain Fahim

Software Engineer

@ The WOS Germany GmbH

About

I'm a Software Engineer with 2+ years of experience building scalable web and mobile applications using React.js, Next.js, and Flutter. Currently working remotely at The WOS Germany GmbH, I specialize in full-stack development, REST API optimization, and Agile methodologies.

Key Achievements

  • ▸Developed and maintained 15+ production features for Lentho.com, serving 5,000+ daily active users
  • ▸Optimized REST API performance, reducing average response time by 40%
  • ▸Implemented secure OTP-based authentication, improving login success rate by 25%
  • ▸Established code review standards, reducing production bugs by 30%

I thrive in collaborative environments where I can deliver high-quality solutions through clean code, thorough testing, and continuous improvement. My approach combines technical expertise with a focus on user experience and system performance.

Strong believer in technology-agnostic problem solving. While I specialize in React, Next.js, and Flutter, I'm highly adaptable and can quickly learn new languages and frameworks like Golang, Rust, or any technology the project demands.
