Job Success
Lahore, Pakistan - 11:41 pm local time
I’m a Full-Stack Developer with 6+ years of experience across SaaS, fintech, mobile and blockchain applications. My core stack includes React, Next.js, Node.js, TypeScript and Ember.js, with additional experience in Vue.js, Nuxt.js, Remix, NestJS and React Native.
I can help with:
• Full-stack SaaS and MVP development
• AI-powered applications and custom AI features
• AI chatbots, RAG systems and LLM API integrations
• Embeddable chatbots connected to business data
• React, Next.js, Vue.js, Nuxt.js and Remix development
• Node.js, Express and NestJS backend development
• Ember.js migrations, upgrades, maintenance and debugging
• REST API and GraphQL development
• Stripe, PayPal and Plaid API integrations
• Fintech dashboards, payments and transaction workflows
• React Native applications for iOS and Android
• WebSockets, Socket IO and real-time features
• Web3 wallets and smart contract integrations
• PostgreSQL, MongoDB, Firebase and Supabase
• AWS, Vercel, Docker and application deployment
I’m comfortable joining an existing team, understanding an unfamiliar codebase and solving problems without turning every assignment into a complete rewrite. I can also take a new product from early requirements through development and deployment.
I have completed several AI-powered applications. One recent project was an embeddable chatbot platform that allows businesses to add a chatbot to their own website. The chatbot connects with the company’s stored data, allowing users to ask questions about sales, performance and other business information in plain language.
My previous work includes SFOX, Outdoorsy, CQR Vault, TenderFi, Zahnymous and GOTO App.
Across these projects, I have worked on Ember.js modernization, trading interfaces, payment flows, booking systems, real-time data and blockchain integrations.
I started my career in design, which still helps me turn Figma designs into responsive, accurate interfaces. I pay attention to the details that often get lost between design and development.
If you already have a codebase, send me the technology stack, the current issue and what you want to achieve. If you’re building something new, share the requirements and I’ll help you define a practical first step.
