Product-minded full-stack developer

I build the quiet systems behindbusy products.

Two years inside real operational software taught me that the best interface is not the loudest one. It is the one that makes a complex workflow feel inevitable.

Position

Frontend specialist by experience. Full-stack engineer by direction. Product thinker by habit.

I work best where data-heavy workflows, reusable interface systems, and real business constraints meet. My recent work spans enterprise dashboards, inventory and product tracking, field-work assignment, reporting, role-based access, and API-driven operations.

I care about the details users feel but rarely name: immediate feedback, predictable state, useful empty screens, resilient loading behavior, keyboard access, and code another developer can safely extend.

Each case notes the problem, the system, and the decisions—not just the technology badges.

Full-stack commerce platform

Shoppershala

A production-minded commerce monorepo where buyers, sellers, and admins each get a purpose-built workflow.

The challenge

Commerce gets messy fast: identity, permissions, catalog discovery, transactions, reviews, analytics, and operational tooling all need to stay coherent.

The system

A layered Express REST API and React SPA connected through a pnpm monorepo, with JWT role-based access, Zod validation, MongoDB, structured logging, and Docker-backed local development.

Key decisions
  • Separated buyer, seller, and admin journeys instead of forcing one generic dashboard
  • Added wallet checkout, reviews, wishlists, seller analytics, and an in-app AI copilot
  • Kept the workspace deployable with CI, shared scripts, seed data, and documented architecture

Realtime collaboration

CoSketch

A collaborative whiteboard that treats drawing as a synchronized system—not a pile of local canvas events.

The challenge

Multiple people need to draw, select, move, and erase at the same time without turning the shared canvas into a conflict machine.

The system

A Next.js and TypeScript client backed by Node.js, WebSockets, PostgreSQL, and Docker Compose for predictable multi-service development.

Key decisions
  • Designed low-latency event synchronization for multi-user drawing sessions
  • Built deterministic selection, shape, and eraser mechanics
  • Containerized the frontend, API, and socket services for local and production parity

Developer tooling

OpenPalette

A complete VS Code customization suite built for developers who want a coherent workspace, not a random bag of extensions.

The challenge

Themes, file icons, folder semantics, and code snippets usually come from separate tools with inconsistent visual language and release processes.

The system

One install delivers 11 dark themes, 300+ file icons, 90+ folder icons, and JavaScript, TypeScript, and React snippets—with automated semantic releases.

Key decisions
  • Curated one consistent developer experience across theme, icon, and snippet layers
  • Added conventional-commit release automation, changelogs, tags, and packaging
  • Kept compatibility with VS Code, Cursor, and other VS Code forks

Backend systems

Cow Hut API

A typed marketplace API with separate user and admin authentication flows and an end-to-end commerce domain.

The challenge

The backend needed secure identity, refresh tokens, profile management, livestock inventory, and order operations without muddying the domain boundaries.

The system

A TypeScript service exposing user, admin, cow, order, and profile modules through REST endpoints with JWT authentication and MongoDB persistence.

Key decisions
  • Separated admin and user authentication, including refresh-token flows
  • Modeled complete CRUD lifecycles for inventory and accounts
  • Documented the live API surface so the contract is easy to test and consume

Operational products

Responsive enterprise dashboards, inventory systems, product tracking, reporting, and real-time field-work assignment interfaces.

02

Data architecture

REST API integration, JWT and role-based access, reusable query flows, Redux Toolkit, and RTK Query for complex application state.

03

Cross-team delivery

Partnered with backend engineers on API contracts, frontend data models, edge cases, Git workflows, and Vercel-based delivery.

04

Quality work

Improved responsiveness, accessibility, maintainability, and performance across data-intensive interfaces and multiple viewports.

How I work

A small set of
strong defaults.

01

Make complexity legible

Good interfaces reveal the system without making people study it.

02

Design for change

Reusable components and clear boundaries beat a clever one-off every time.

03

Performance is product

Fast, stable, accessible software is not polish—it is the experience.

04

Own the handoff

A feature is not finished until the API contract, edge cases, and deployment story make sense.

Off the clock

Good software needs a life outside software.

Music for focus. Movies for new perspectives. Long walks, open air, and new places for the reset button. Curiosity travels well between code and everything else.
