Welcome to My Software Engineering Blog

Hello! I am Salman Ar Rahman, a Full-Stack & Backend Software Engineer.

I created this technical space to document real-world engineering challenges, architectural design decisions, and practical lessons learned from building enterprise platforms.

🚀 What I Write About

Here are the key topics and technical areas I will be covering:

1. High-Throughput Backend & APIs

• Modern API architecture with Python 3.13, FastAPI, and SQLAlchemy 2.0.
• Zero-downtime database migrations with PostgreSQL 15 and Alembic.
• High-performance connection pooling and query optimization.

2. Distributed Web Automation & Worker Fleets

• Architecting resilient distributed Selenium worker fleets with automated heartbeat monitoring and failover.
• Reliable CAPTCHA bypass pipelines with CapSolver and proxy rotation.
• Production scheduling with APScheduler and message queues.

3. Cloud & DevOps on AWS

• Containerized microservices on AWS ECS Fargate, RDS, and SQS.
• Automated CI/CD pipelines using AWS CodePipeline and Docker.
• Structural inspection data analysis and automated PDF reporting pipelines.

4. Bilingual Engineering in Japan

• Practical strategies for learning Technical Japanese (JLPT N3 / N2) as a working software developer.
• Collaborating in international, cross-functional agile teams.
