Full Stack Developer

Rahul Dhaka

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.

My Journey

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.

AI-Augmented Engineering

Hand him a problem, get back a shipped feature

Rahul takes a feature from idea to live — backend, frontend, and the AWS behind it — and documents it cleanly for handover. He moves fast with an AI-first workflow, but the architecture, security and cloud-cost calls are his own.

Owns the whole slice

Database schema to deployed UI to the AWS it runs on — end to end, no gaps between specialists.

Cuts the cloud bill by design

Built a CloudFront + WAF + API Gateway layer for WriteBetter that dropped Lambda calls on cached routes from ~10k/hr to single digits.

Tracks AI cost to the cent

Monitors per-model API spend (GPT, Whisper, Realtime) and prices features per user-minute so margins stay healthy.

Ships real AI features

Voice-to-text on the OpenAI Realtime API, AI-generated analytics reports, and an engine that auto-generates app navigation from any URL.

How AI Fits the Daily Workflow

Sets up AGENTS.md, project rules and reusable skills so AI output stays aligned with the architecture.
Builds, refactors and tests paired with Claude in Cursor.
AI-reviews every change for bugs, security and performance before release.
Designs infra so repeat or abusive traffic never reaches — and bills — Lambda.

Major Projects

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

Read full case study

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

Read full case study

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.
