Open to Associate Software Engineer · Dhaka / Remote

I transform ideas into real-world products with full-stack engineering & scalable systems.

I’m Shahriar, a software developer who enjoys turning messy constraints into clean dashboards, robust APIs, and reliable backends. Working end-to-end with Next.js, Node.js, TypeScript, and MongoDB, and building IoT integrations when products need real-world data.

About

Builder, problem-solver, and relentless debugger.

I’m a CSE graduate who prefers real deployments over hypothetical diagrams. I enjoy working where code has consequences: production dashboards, physical devices, and users who rely on the system every day.

What I like working on

  • Designing clear dashboards with strong UX and real-time data.
  • Architecting APIs, auth flows & data models for SaaS products.
  • Connecting hardware (ESP32, sensors) to the cloud.
  • Collaborating closely with founders & domain experts.

I care a lot about clarity: clear UI, clear APIs, clear expectations. If something is confusing, we redesign it.

Experience & mindset

How I work with teams & products.

Early-stage mindset

Comfortable with ambiguity, tight budgets, and rapid feedback loops. I like to break big visions into clear phases and ship something useful early.

Owner, not just implementer

I care about uptime, on-boarding, documentation, and post-launch improvements - not just pushing code and disappearing.

Sports & discipline

Being a futsal captain and a 10km runner keeps me disciplined, team-oriented, and competitive - the same energy I bring into codebases.

Contact

Let’s build something useful, not just “cool”.

I’m open to Associate Software Engineer roles, IoT/SaaS collaborations, and focused freelance projects. Share a bit about your product and constraints - I’ll reply with honest thoughts and possibilities.
