Job Success
Tangail, Bangladesh - 7:12 pm local time
Most of my work starts the same way: an existing production system, an original developer who is gone, and a client who needs it to just work again. I read unfamiliar codebases fast, find the real cause instead of patching symptoms, and leave the system in a state the next person can maintain.
WHAT I DO
• Rescue & stabilize production apps — crashes, broken deploys, silent failures
• Symfony & Laravel development and legacy upgrades (PHP 5 to 8, Symfony 2 to 6)
• REST API development and third-party integrations
• Performance tuning — Redis caching, Elasticsearch, query optimization
• DevOps — Docker, AWS, DigitalOcean, Linux, CI/CD, RabbitMQ workers & schedulers
• ERPNext / Frappe customization, deployment and integrations
PROOF THAT CLIENTS KEEP ME
My two longest engagements ran 1,463 hours and 1,431 hours with the same clients — one of them for over three years. Across 26 contracts I average around 260 hours per client, because the work does not come back broken.
RESULTS I'VE DELIVERED
• Migrated and dockerized a legacy Symfony 3 application into a reproducible local + production setup
• Cut response times on a high-traffic directory platform with Redis caching and Elasticsearch tuning
• Fixed multi-party WebRTC stability on iOS after months of intermittent dropouts
• Resolved queue and worker failures in ERPNext following a server migration
BEST FIT FOR
• Existing systems that need rescuing, upgrading or scaling
• Apps hitting performance or reliability limits
• Long-term maintenance and ongoing development partnerships
Not a fit for: brand-new WordPress sites, template theme work, or one-hour "just make it work" fixes with no access to the codebase.
If you have a live system that needs someone who can step in, understand it, and make it solid — send me the details and I'll tell you honestly whether I'm the right person.
