Software Engineer · IT Administrator

Sultan Mehedi Masud

I build software, manage infrastructure, and turn business requirements into reliable technology.

I work across software engineering and IT operations — developing business applications, ERP platforms, APIs and dashboards while also managing deployment infrastructure, office systems, networks, endpoints and technical operations.

Open to software engineering, IT administration, infrastructure and enterprise systems opportunities.

About

About Me

Portrait of Sultan Mehedi Masud

I’m Sultan Mehedi Masud, a Software Engineer and IT Administrator based in Dhaka, Bangladesh.

My experience sits at the intersection of software development, infrastructure and business operations. I develop production applications and enterprise systems while also understanding the practical IT environments where organizations operate.

This combination allows me to approach technology from both sides: building systems and making sure the surrounding infrastructure works reliably.

  • IT Infrastructure
  • Systems Administration
  • Enterprise Software
  • ERP Systems
  • Networking
  • Cybersecurity
  • Cloud Infrastructure
  • Business Process Automation

Two disciplines

Two disciplines. One technology perspective.

My background combines software engineering with hands-on IT administration. I build the systems a business runs on, and I understand the environment they run in.

Software Engineering

I design and develop business-focused applications, backend systems, APIs, dashboards and enterprise workflows with an emphasis on maintainability, security and practical business value.

  • Full-stack web applications
  • Backend APIs
  • ERP systems
  • Administrative dashboards
  • Database architecture
  • Authentication and authorization
  • Business workflow automation
  • Production deployment

IT Administration & Infrastructure

I manage the systems people depend on every day, from Windows endpoints and office networks to CCTV, attendance systems, printers, shared storage and remote support.

  • Windows administration
  • User and endpoint management
  • CCTV
  • Attendance devices
  • Printers and scanners
  • NAS storage
  • LAN and Wi-Fi
  • Remote administration
  • Hardware troubleshooting
  • Backup and access management

Build. Secure. Deploy. Operate.

Software only works when the systems around it do. I work across every stage, from the first requirement to the last endpoint.

Software engineering

Building systems around real business workflows

My software engineering work focuses on practical systems that organizations actually use — ERP platforms, internal applications, administrative dashboards, APIs, authentication systems and operational workflows.

Rather than focusing only on interfaces, I work across:

  • Requirements
  • Backend architecture
  • APIs
  • Databases
  • Permissions
  • Business logic
  • Frontend administration
  • Deployment
  • Production support
