About
I’m Aboy Chandra Das. I build the systems small teams run on.
I’m a full-stack developer working under the name Aboy Systems. I build business web apps — dashboards, CRM systems, automation tools, and the admin workflows behind them — with Next.js, React, TypeScript, and Tailwind CSS.
I’ll be straight about where I am: I’m at the start of my freelance career, and I don’t have a wall of client logos. What I have instead is proof of work — self-initiated systems like FieldOps Analytics OS, designed, built, and deployed end to end, and build roadmaps treated with the same rigor a paid project would get.
The bet I’m making is simple: show, don’t claim. Every project on this site is labeled for exactly what it is, every scope I quote is one I can deliver, and if your project isn’t a good fit, I’ll say so and point you somewhere better.

Problem space
How I build
Principles that show up in every project.
Not aspirations — habits you can verify in the work and the repos.
Business-first thinking
Screens exist to answer questions and save hours. The build starts from your workflow, not from the tech.
Clean, calm UI
Dense where it helps, quiet everywhere else. Dashboards should read like instruments, not fireworks.
Reusable components
Design systems over one-off screens — it's why my builds stay consistent and fast to extend.
Responsive by default
Built for the office laptop and the phone between site visits — not desktop-only demos.
Documented on GitHub
Readable commits and written notes, so the project stays understandable long after handoff.
Deployment-ready
Every build ships to a real URL with deployment notes — a working product, not a zip file.
Current focus
What I'm working on right now.
Building portfolio-grade business systems
Self-initiated products like FieldOps Analytics OS — real builds that prove the playbook end to end, plus scoped roadmaps held to the same standard.
Sharpening real-world full-stack workflows
Going deeper on data modeling, testing with realistic edge cases, and deployment practice with every build.
Opening up to global freelance clients
Preparing Aboy Systems for remote client work on Upwork, Fiverr, Freelancer, and LinkedIn — leading with proof instead of promises.
The proof matters more than the pitch.
