Software Engineer
I model systems before I write code — backend architecture and integrations that ship measurable outcomes, not just features.
My engineering journey
Software Engineer
SpaceSoft Limited · Mirpur DOHS, Dhaka
Rearchitected FieldTask and raised marketplace-driven revenue 416%.
- Rearchitected the app to support scheduling, stale and real-time tracking, invoicing, and job workflows.
- Integrated natively with the GoHighLevel marketplace; engineered the installation workflow and implemented two-way sync for core features (appointments, contacts, timesheets, etc.), ultimately raising revenue by 416%.
- Collaborated directly with clients to understand market demands, explain technical workflows, and prepare a roadmap to expand business goals.
- Engaged in meetings with GoHighLevel engineering teams to request necessary API endpoints.
Junior Software Engineer
SpaceSoft Limited · Mirpur DOHS, Dhaka
Cut FieldTask build times 6x and shipped Apploye's Settings feature.
- Optimized the FieldTask development lifecycle by migrating the legacy frontend build system from Babel to Vite, reducing production build times by 6x and improving development speed by 43%.
- Developed the Settings feature for Apploye, providing control over both organizational and member-level settings. Worked across React and Django microservices.
Software Engineering Intern
Swosti Limited · Karwan Bazar, Dhaka
Built RESTful APIs and multilingual financial reporting in Spring Boot.
- Developed RESTful APIs using Java Spring Boot, implementing robust global exception handling, transaction management, and optimized payloads for seamless frontend consumption.
- Designed and tuned complex PostgreSQL queries to generate high-compliance, multilingual PDF financial reports mapping directly to MRA and MFI operational metrics.

How I engineer
The instincts that shape every decision, not just the ones that make it into a changelog.
Model systems before writing code
Whether it's reactor thermal-hydraulics or a REST API, I isolate the variables that actually matter before I touch an editor.
Solve business problems, not puzzles
Clever code that doesn't move a real number is a hobby, not engineering. I optimize for outcomes clients can point to.
Measure before optimizing
I don't guess at bottlenecks — build time, query latency, and bundle size all get profiled before I touch them.
Build for the team that inherits it
Boundaries and responsibilities should still make sense six months later, to someone who wasn't in the room when I wrote it.

When I'm away from coding
Decisions that shaped the path
Nuclear Engineering → Software Engineering
Started an M.Sc. in Nuclear Engineering, fell in love with the systems-thinking side of it, and realized I wanted to apply that thinking to software's faster feedback loops.
SaaS over freelancing
Chose to go deep on one product's long-term architecture rather than spread across short-term client work.
Specialized in backend architecture
Gravitated toward the systems, data, and integration layer — the part of the stack where a bad decision compounds the most.
Prefer long-term product development
I'd rather own a feature's second and third iteration than hand it off after the first launch.
