Who I Am
I'm Mahabub Alam Arafat, a passionate Software Engineer with over 2 years of hands-on production experience. Currently working at ShareTrip, Bangladesh's leading travel technology company, where I've been instrumental in transforming legacy systems and building scalable microservices that serve millions of users.
What sets me apart is my ability to take complex problems and break them down into elegant, maintainable solutions. I don't just write code—I architect systems that can scale, perform, and evolve with business needs.
My Journey
My path into software engineering is unconventional but purposeful. I graduated with a degree in Mechanical Engineering from Chittagong University of Engineering and Technology (CUET), but my passion for technology and problem-solving led me to pursue software development through self-learning and practical projects.
🎯 Self-Taught Excellence
I believe in learning by doing. Every skill I've acquired, from NestJS to microservices architecture, came from diving deep into real-world problems and building solutions that matter. This approach has given me a unique perspective on software development—I understand not just the "how" but the "why" behind every technical decision.
What I Do
At ShareTrip, I've been involved in some of the most critical system transformations:
- API Performance Revolution: Rewrote the legacy booking API using NestJS and TypeScript, reducing response times from 20-30 seconds to 8-9 seconds (3-4x improvement)
- Microservices Architecture: Led the transformation of a monolithic flight booking system into three specialized microservices, reducing API calls by 60% and database operations by 80%
- Cost Optimization: Built a centralized cron job microservice that eliminated wasteful operations and reduced AWS costs by 30%
- Production Problem Solving: Created a custom memory-tracking package that solved a company-wide memory leak issue affecting all API traffic
- AI Automation: Developed an AI-enhanced visa automation bot that cut manual processing time by 80% for select countries
My Technical Philosophy
I believe in writing code that tells a story. Every function, every class, every microservice should have a clear purpose and be maintainable by the next developer who touches it. My approach combines:
- Performance First: Every line of code is written with performance implications in mind
- Scalability by Design: Systems should grow gracefully with business needs
- Team Collaboration: The best solutions come from diverse perspectives working together
- Continuous Learning: Technology evolves rapidly, and so should we
- Real-World Impact: Code should solve actual problems and create value
Beyond Code
When I'm not architecting microservices or optimizing APIs, I'm sharing my knowledge through technical writing. My blog features real-world stories from production environments—the challenges, the solutions, and the lessons learned. I believe in transparent knowledge sharing because the best way to grow is to help others grow too.
🚀 Always Learning
Currently exploring advanced cloud architectures, AI/ML integration in backend systems, and emerging technologies that can solve tomorrow's problems today. I'm particularly interested in how AI can enhance developer productivity and system reliability.
Why Work With Me?
- Proven Results: Track record of delivering measurable improvements in production environments
- Full-Stack Mindset: Understanding of the entire technology stack, from database optimization to user experience
- Problem Solver: I don't just implement features—I solve business problems through technology
- Team Player: Strong collaboration skills with QA, DevOps, and product teams
- Communication: Ability to explain complex technical concepts to both technical and non-technical stakeholders
- Adaptability: Quick to learn new technologies and adapt to changing requirements
