Full Stack Developer
Resume profile for Rahul Dhaka, Full Stack Developer at Webnyxa Technologies.
H-53, First Floor, Office No. 01, Sec 63, Noida, Uttar Pradesh - 201301, IN.
Professional Summary
Full-Stack Developer with 4+ years of experience building production-grade web platforms, SaaS dashboards, CMS-driven sites, and AI-powered products. Strong across Node.js/NestJS backends, Next.js/React frontends, MongoDB/SQL data layers, and AWS serverless deployments. Uses Claude, Cursor, ChatGPT, GitHub Copilot, and OpenAI models daily for architecture planning, schema/API design, code scaffolding, debugging, refactoring, documentation, and product-quality reviews — while keeping full engineering ownership of security, maintainability, cost, and production behavior.
I started as a frontend developer in React, then moved into backend work and grew into a full-stack engineer across the Node.js and JavaScript ecosystem. Over time I added Next.js, NestJS and AWS serverless, and rebuilt my day-to-day workflow around AI as a genuine force multiplier.
At Webnyxa I own end-to-end delivery for SaaS products, dashboards, CMS-driven websites and AI-enabled applications — backend architecture, database design, frontend implementation, deployment and production monitoring. I use Claude, Cursor, ChatGPT and GitHub Copilot daily for architecture exploration, schema/API planning, scaffolding, debugging, refactoring and documentation, with manual review and production standards applied before every release.
I've shipped OpenAI-powered writing flows, real-time voice-to-text, AI-generated analytics reports, and AI website-crawling features that turn manual setup into automated product experiences — while keeping security, cost and architecture decisions firmly under engineering control.

Projects I Worked On
Jpetto.io
Overview
Marketing and product-suite website built from the ground up with Next.js App Router, SSR/SSG pages and a Sanity CMS content layer, deployed on AWS with CI/CD.
Key Contributions
- Built the site from scratch with Next.js App Router, SSR/SSG pages, reusable UI components and a Core Web Vitals-focused implementation.
- Created design components, boilerplate, architecture plans and AGENTS.md / project-specific AI instructions so coding agents generate consistent UI and code, reducing designer dependency and delivery time.
- Integrated Sanity CMS with AI-assisted schema design for flexible content models — giving editors control over product pages, blogs, media, SEO fields and GTM/script config without code changes.
- Designed a layered architecture around content services and CMS boundaries so Sanity can be swapped later without a full rewrite.
- Deployed on AWS with CI/CD across staging and production, keeping releases predictable for client review and go-live.
- Documented CMS workflows and technical decisions with AI-assisted docs so future developers and non-technical editors ramp up faster.
WriteBetter — AI Writing Assistant
Overview
AI-powered writing assistant shipped across iOS, Android and a browser extension, with a NestJS backend running serverless on AWS Lambda.
Key Contributions
- Architected the scalable backend with modular APIs for writing assistance, user sessions, subscriptions, usage tracking and audit history.
- Integrated OpenAI models for chat/rewrite flows and the OpenAI Realtime API for real-time voice-to-text, with session tracking and backend safeguards that block abuse without slowing genuine usage.
- Designed model-selection and prompt strategies around quality, latency and cost — using GPT-4o / GPT-4o mini per workload instead of treating every request the same.
- Built the admin dashboard in Next.js + Tailwind for users, subscriptions, analytics and growth, including an AI-generated reporting flow that turns usage metrics into readable product insights.
- Reviewed the MongoDB data model across ~20 collections, mapping relationships to guide scalable storage, audit history, analytics and subscription workflows.
- Deployed on AWS Lambda with GitHub Actions CI/CD, cold-start reduction, memory tuning, CloudFront caching, AWS WAF, API Gateway throttling, CloudWatch alerts and billing controls to cut abuse, latency and unnecessary cloud cost.
NoShopCode Admin Dashboard — Universal Shopify App Runner
Overview
Centralized admin configuration portal to manage multiple Shopify-based mobile apps, client settings, permissions and role-based admin/client access.
Key Contributions
- Designed and built the centralized portal for managing many Shopify-based mobile apps with role-based admin/client access.
- Engineered an AI-powered feature that crawls client websites, extracts full navigation menus with nested links, and generates structured config trees in minutes to auto-configure dynamic app sidebars.
- Built reusable configuration modules and API contracts so new client apps onboard with less custom engineering and fewer manual steps.
- Integrated OneSignal push notifications for bulk and segmented campaigns, offers and retention — contributing to a 30% sales uplift for the client.
- Implemented end-to-end encryption for configuration payloads and responses, protecting sensitive data between the admin portal and mobile apps.
Sova — Security Management System
Overview
Real-time security operations platform with live event streaming, granular role-based access and compliance-oriented session handling.
Key Contributions
- Developed a real-time backend with Node.js and Ably WebSockets for live security event streaming, reducing event latency to under 500ms.
- Engineered granular RBAC across 5+ roles to dynamically control UI elements, routes and backend capabilities, using AI-assisted edge-case analysis and documentation to validate permission behavior faster.
- Improved application performance by 40%+ through custom React hooks, memoization, state-management cleanup and AI-assisted refactor planning for complex UI flows.
- Integrated JWT authentication, secure session handling and encrypted data transmission for compliance-oriented security workflows.
Hidden — Subscription-Based Social Platform
Overview
Pay-per-view subscription platform letting creators publish premium content behind a paywall — reached 1.72M monthly visits with 102% MoM growth.
Key Contributions
- Built the pay-per-view platform enabling creators to publish premium content behind a subscription/paywall model; reached 1.72M monthly visits with 102% MoM growth.
- Developed the SSR web app with Next.js and a scalable NestJS backend, using Redux-Saga for complex async flows and Ant Design for a polished, responsive UI.
- Integrated AWS S3 for secure, scalable media storage/delivery — reducing upload time by 30% while improving creator-media availability across regions.
- Built creator-content, subscription, media-metadata and access-control API flows to support paywall behavior and premium-content visibility.
- Used Claude/Cursor for component scaffolding, Redux-Saga flow breakdowns, API integration reviews and documentation — accelerating delivery while keeping manual review on subscription/payment-sensitive logic.
