I build dashboards, CRM systems, automation tools, and admin workflows using Next.js, React, TypeScript, and Tailwind — with database integration, CSV exports, and clean user experiences.
Aboy Chandra Das · Aboy Systems
One developer, end to end — the person you message is the person who designs, builds, and ships your system.
TypeScript end to end with validated inputs — no mystery scripts holding the business together.
CSV import and export are first-class features, so your data never gets trapped inside the app.
Short written updates and demo videos as the build progresses — made for working across time zones.
The problem
Most small teams aren't short on tools. They're short on one system that matches how the work actually happens.
One workbook, six tabs, formulas nobody dares touch. It breaks quietly — usually at month-end.
Orders in one tool, clients in another, and the weekly report assembled by hand every Friday.
Revenue, stock, and workload are only visible after someone stops real work to compile them.
Generic tools bent out of shape, so the real process ends up living in chat threads and memory.
Every one of these is a systems problem — and a system is something you can build. That’s the job.
Services
Three ways I help businesses replace manual work with software they own.
Live views of revenue, operations, and team output — replacing the weekly copy-paste report.
Leads, deals, and client history in one pipeline — built around your sales process, not a template.
Multi-step manual processes turned into guided flows with rules, roles, and an audit trail.
Featured work
Self-initiated products that prove out real business workflows. No invented clients — the label on each card says exactly what it is.
An e-commerce operations dashboard that turns raw store data into daily decisions — orders, revenue, stock, and channel performance in one live view.
A CRM for agencies and service businesses — leads, deals, tasks, and client history in one pipeline instead of five tools and a group chat.
An operations dashboard for field-service teams — jobs, technicians, and performance in one place instead of a whiteboard and three spreadsheets.
Stack
A focused stack for dashboards, CRM tools, admin panels, data workflows, and deployment-ready portfolio projects.
Frontend
Component-based UI — the base of every screen I build.
The framework behind every app I ship — routing, rendering, and APIs in one place.
Types end to end, so bugs surface while building — not after handoff.
The language under everything. I keep it modern and readable.
Fast, consistent styling without a pile of custom CSS.
Small, subtle animations — enough to feel polished, never showy.
Backend & Database
Server-side logic for APIs, imports, and scheduled work.
Typed database access — queries the compiler can check.
My default database for business data that has to stay consistent.
Light, file-based storage for small tools and internal apps.
Validates every form and import, so bad data stops at the door.
Data & Analytics
Data cleanup and scripting when spreadsheets get messy.
Heavy lifting for CSV and Excel data before it reaches the app.
Quick data tools and internal prototypes in pure Python.
Clean dashboard charts — readable first, decorative never.
Tools & Deployment
Version control on every project, from the first commit.
Where my projects live — commits you can actually follow.
Deployment for every build — live URLs and preview links.
Process
No black box. You approve the plan before I write code, and you see progress every week.
01
A clear project message and workflow walkthrough inside the platform — what you use now, what is slow, and what needs to be easier.
02
I write up the data model, screens, and roles. You approve exactly what gets built before code starts.
03
Working software on a live preview link every week — feedback early, no big reveal at the end.
04
Deployment, documentation, and a walkthrough video. Your team owns the tool, not just a login.
