Aaditya Gupta — Full Stack Developer
Full stack developer.in Kathmandu, Nepal
From architecture to production code
I engineer web applications that perform end-to-end — from intuitive, pixel-perfect user interfaces to resilient backend APIs and scalable databases.
Specializing in Next.js, React, Node.js, and TypeScript, I bridge the gap between design engineering and system reliability. Based in Kathmandu, I help startups, businesses, and agencies in Nepal and across the globe ship fast, accessible, and SEO-optimized digital products.
A high-volume trading and client management ecosystem built for Nepal Stock House (Broker No. 14). Integrates digital KYC onboarding, real-time portfolio analytics, and automated order tracking with bank-grade security protocols.
Architecture: Engineered with Next.js App Router, React 19, TypeScript, and Tailwind CSS. Features real-time state synchronization, payment gateway integration, responsive administrative portals, and sub-second page transitions.
Next.js, React, TypeScript, Tailwind CSS, REST APIsView case study
A scalable bi-directional instant messaging application featuring real-time natural language sentiment analysis and automated content moderation to protect community integrity.
Architecture: Built with React and Tailwind CSS on the frontend, powered by a Node.js and Express WebSocket (Socket.io) server. Microservice architecture decouples the Python/Django sentiment analysis inference pipeline.
An end-to-end e-commerce storefront paired with a custom multi-role administration dashboard for managing inventory, tracking order lifecycles, and processing customer checkouts.
Architecture: Built with vanilla JavaScript, PHP, and MySQL. Features normalized relational database schemas, secure session authentication, dynamic filtering, and optimized catalog rendering.
A comprehensive automotive portal and marketplace focused on electric vehicles. Delivers deep technical specifications, comparison tools, and structured editorial content.
Architecture: Built with Next.js, React, and Tailwind CSS. Employs Static Site Generation (SSG) with incremental caching, zero-layout-shift UI components, and automated metadata for organic SEO discovery.
If you need a Full Stack Developer in Nepal, I take products from initial concept through high-fidelity UX prototyping, backend engineering, database optimization, and cloud deployment.
Currently working as a full stack developer and UI/UX designer at Cognix Insights, I bridge business objectives with technical precision. Every line of code is written with accessibility, performance, and long-term maintainability in mind.
Building accessible, high-performance web applications using Next.js (App Router, Server Components), React 19, and TypeScript. Interfaces are engineered with Tailwind CSS, Framer Motion, and Radix UI primitives for fluid interaction without layout shifts.
Architecting resilient RESTful APIs and real-time WebSocket endpoints using Node.js and Express. Microservices and background worker queues handle compute-heavy operations, with JWT, OAuth2, and session-based security layers.
Eliminating the traditional designer-developer friction. As a hybrid UI/UX designer and full-stack engineer, I transform Figma prototypes into pixel-perfect, accessible code with complete fidelity to design tokens, typography, and UX intent.
Deploying scalable web applications on modern cloud platforms like Vercel, Docker containers, AWS, and Cloudflare. Automated GitHub Actions pipelines ensure continuous integration, unit testing, and instant zero-downtime releases.
Focus: Vercel, Docker, AWS, Cloudflare, GitHub Actions, Linux

Technical SEO & performance hardening
Every web application is engineered for search engines from day one. Utilizing server-side rendering (SSR), automated JSON-LD structured data, OpenGraph protocols, and strict Core Web Vitals optimization to rank on competitive Google search results.
Focus: JSON-LD schema, Core Web Vitals, semantic HTML5, automated sitemaps

Engineering workflow
The whole picture, one builder.
A disciplined five-phase delivery model ensuring your web application is strategically planned, cleanly coded, thoroughly tested, and deployed without friction.
01
Discovery and system architecture
We begin with a deep technical evaluation of your business goals. I define the database entity-relationship models, choose the right tech stack (SSR vs. SSG vs. SPA), plan REST and WebSocket endpoints, and establish architectural blueprints.
02
UI/UX design and interactive prototypes
Before writing code, I design user journeys, responsive wireframes, and high-fidelity prototypes in Figma. Establishing design tokens, typography, and spacing systems ensures visual consistency and rapid frontend implementation.
03
Backend engineering and database setup
I construct the data tier: designing normalized SQL or NoSQL databases, writing secure RESTful APIs with input validation, configuring authentication (JWT/OAuth), and building business logic with automated testing.
04
Frontend integration and state orchestration
The UI is built with reusable React and Next.js components and typed TypeScript interfaces. Live API connections, optimistic UI updates, error boundary fallbacks, and micro-interactions bring the product to life.
05
Security hardening, SEO and CI/CD launch
Prior to launch, the system undergoes security auditing (OWASP Top 10), Core Web Vitals optimization (LCP < 1.2s), automated JSON-LD schema injection, and CI/CD automated deployment to Vercel or cloud servers.
Value and advantage
Why hire a full stack developer in Nepal?
01 — Hybrid velocity
Designer and engineer in one
By mastering both UI/UX design (Figma) and full-stack software architecture (Next.js, Node.js), handoff translation errors disappear completely. You save 30-40% on overhead and ship weeks ahead of schedule.
02 — Global standards, local agility
World-class code quality
You receive clean, modular TypeScript architectures adhering to international security and performance standards (OWASP, Core Web Vitals) at highly competitive freelance and contract rates.
03 — Async & timezone overlap
Seamless remote collaboration
Based in Kathmandu (GMT+5:45), I offer flexible hours overlapping with North American mornings, European business days, and Australasian work hours with crystal-clear English communication.
