Hi, I'mDhaka, Bangladesh
Senior Full-Stack Engineer
I build and lead the systems that move freight, money, and teams — from first commit to production incident response.
Pronab Chandra Saha
Senior Full-Stack Engineer & Engineering Manager
Full-stack engineer and engineering manager with 18 years of software development experience, including 12+ years working directly with US-based companies across LAMP and MERN stacks. Deep domain expertise in freight and logistics technology — dispatch systems, fleet tracking, TMS platforms, ELD and load-board integrations, and compliance/mapping data providers — with ownership spanning from first commit through production incident response. Additional background in payments and fintech, including gateway integrations, fraud detection, and audit logging for cross-border transaction platforms.
I started shipping software in 2008 as an independent developer for international clients, which taught me early that the person who writes the code also owns what happens when it breaks at 2 a.m.
From 2014 I moved into payments and e-commerce at Kashmart International, building gateway integrations, fraud-detection hooks, and audit logging on a high-volume cross-border transaction platform. Then came six years as a core engineer on an international logistics platform at PNS Management, integrating freight APIs, mapping services, and compliance data providers on a hardened LAMP stack.
In 2023 I stepped into management at SOLVERS, leading a portfolio of product and client engagements while staying hands-on. I returned to PNS to build on Node.js, React, and MySQL — delivering ELD and load-board connectivity — and later supported the same platform's operations and incident response from the other side of the table.
Today I'm deepening my infrastructure and AI/ML skills — RHEL, Ansible, Kubernetes, CI/CD, AWS, and a locally hosted LLM for logistics decision support — and I'm open to remote engineering, platform, and engineering-management roles.
Build dependable systems for industries where software failure has real-world consequences, and grow engineers who can do the same.

Career Break — Infrastructure & AI/ML Deepening
First commit through production incident response. Ownership isn't a hand-off; it's the job.
Query optimization, caching, monitoring, and hardened infrastructure are how uptime actually gets delivered.
Coding standards, code review, and structured sprints reduce defects and make release cadence predictable.
Ten-plus years across an 11-hour time difference: clear writing, US-hours overlap, and delivery without close supervision.
TMS platforms, dispatch systems, fleet tracking, ELD and load-board integrations, mapping and compliance data providers.
Gateway integrations, fraud detection, audit logging, and cross-border transaction compliance.
Set coding standards, run sprint planning and retrospectives, and manage engineers while shipping code.
RHCE and RHCSA certified; RHEL, Ansible, Docker, Kubernetes, CI/CD, and AWS architecture.
