Hi, I’m Santo (Mojibur Rahaman) — a Software Engineer and AI/ML enthusiast focused on building intelligent, scalable, and high-performance applications.

I specialize in backend development with PHP and Go, with day-to-day work around API design, microservices, and database systems — including time-series data used in trading and analytics workloads. I care about clean architecture, maintainable code, and systems that stay reliable under real production traffic.

Alongside platform engineering, I explore AI and machine learning as a way to make products more data-driven: better reporting, smarter automation, and clearer decision support for users and operators.

I help founders and teams turn ideas into working software — from early MVPs to long-lived production systems — with a practical bias toward clarity, performance, and shipping things people can trust.

  • APIs & backends — Designing and maintaining REST services in PHP (Laravel/Symfony), Golang, and C# for web and desktop clients.
  • Microservices — Debugging, integrating, and evolving service boundaries in distributed systems, including messaging with RabbitMQ and containerized delivery with Docker.
  • Trading & data platforms — Contributing to production trading systems: data analysis, reporting features, and services that need to be accurate and dependable.
  • Product engineering — Building end-to-end applications such as filing automation, marketplaces, e-wallets, and e-commerce when the work calls for full-stack delivery.

How the stack fits together — from interface and service code through parallel data stores, source control, container packaging, and production.

AI Trade builds technology around trading workflows and market data. Since joining as an intern and growing into a full-time software engineer role, I’ve worked primarily on backend services that power APIs, integrations, and reporting across the platform.

Software Engineer

Full-time

Present

Own and improve production backend work used by internal tools and client-facing trading experiences.

  • Build and maintain RESTful APIs with PHP (Symfony/Laravel), Golang services, and C# desktop application support.
  • Investigate and resolve issues inside the microservices architecture — services, contracts, and the paths between them.
  • Extend data analysis and reporting capabilities so operators and users can understand platform activity more clearly.
  • Ship incremental improvements with an eye on reliability, readability, and long-term maintainability.

Software Engineer Intern

Internship

Entered the engineering team supporting backend delivery on a live trading-related platform.

  • Contributed to API-driven features and service integrations while learning the domain and codebase.
  • Worked with RabbitMQ-based messaging flows and Dockerized environments used in development and deployment.
  • Grew into stronger ownership of backend tasks, which led into the full-time software engineer role.
