Build Private Web App for Affiliate Deeplink Generation
Abdul built our entire affiliate deeplink platform (Afflu) from scratch, a private web app with complex features including deeplink generation, multi-category filtering, brand management, CSV exports, and a full privacy policy integration.
What impressed us most was how confidently he handled the technical complexity. We went through multiple rounds of feedback and feature changes, and Abdul adapted incredibly fast every single time without compromising quality. He didn’t just execute, he truly thought alongside us, proactively suggesting smarter solutions and catching potential issues before they became real problems.
On the technical side: the app is built with a clean, modern stack and runs flawlessly in production. Abdul managed everything end-to-end (frontend, backend, database, and deployment) with zero hand-holding. It genuinely felt like working with a senior engineer who fully owns the product.
On the management side: this is where Abdul really exceeded expectations. His communication was outstanding: always clear, proactive, and transparent. He set expectations well, respected timelines, and kept everything structured and under control, even as the project evolved. We always felt aligned, informed, and confident about the direction of the work. Working across time zones was effortless thanks to his responsiveness and organization.
Overall, working with Abdul has been an exceptional experience. We’re already planning to continue with him on the next phase, and honestly, we wouldn’t hesitate to recommend him to anyone looking for a top-tier full-stack developer who combines strong technical skills with true ownership and professionalism.

Totally trustworthy, and I’ll definitely keep working with him for future enhancements and maintenance.

Job Success
Mansehra, Pakistan - 7:01 am local time
I build full-stack SaaS products and AI-powered systems, chatbots, voice agents, RAG assistants, and workflow automation that help businesses scale faster and eliminate manual work.
If you need a developer who can own the entire product (frontend + backend + AI + deployment), ship fast, and think like a product engineer, you're in the right place.
WHO I HELP
Startup founders building MVPs and scaling to product-market fit. SaaS companies adding AI features (copilots, chatbots, smart search) to their platforms. Agencies and businesses automating operations, customer support, lead qualification, knowledge management, and internal workflows.
PROBLEMS I SOLVE
On the product & engineering side: You need an MVP built fast. Your app is slow and doesn't scale. Your codebase is messy and hard to maintain. You need a production-grade SaaS platform with auth, billing, dashboards, and APIs.
On the AI & automation side: Your team wastes hours on repetitive tasks that could be automated. Customers wait too long for support answers. Your knowledge base is scattered and unsearchable. You want to integrate LLMs into your product but don't know where to start.
FULL-STACK SOLUTIONS I BUILD
SaaS platforms (multi-tenant, billing, RBAC, analytics dashboards). Web applications with Next.js, React, and TypeScript. Cross-platform mobile apps with React Native. RESTful and GraphQL APIs with Node.js and Express. Database architecture with PostgreSQL and MongoDB. Cloud infrastructure on AWS with Docker, CI/CD, and monitoring.
AI & AUTOMATION SOLUTIONS I BUILD
AI chatbots and customer support bots (OpenAI, Claude, custom LLMs). Voice AI agents for phone-based customer interactions. RAG knowledge assistants, connect your docs, PDFs, and databases to an AI that actually answers questions accurately. AI copilots embedded inside SaaS products. LLM-powered workflow automation with LangChain, n8n, and custom pipelines. AI agent development, autonomous agents that take actions, not just answer questions. Custom integrations with OpenAI, Claude, Gemini, Whisper, and vector databases (Pinecone, embeddings).
TECH STACK
Frontend: React, Next.js, TypeScript, Tailwind CSS, React Native
Backend: Node.js, Express, Nest.js, FastAPI, GraphQL, WebSockets
Databases: PostgreSQL, MongoDB, Redis
AI/ML: OpenAI (GPT-4, Whisper, Embeddings), Claude, Gemini, LangChain, Pinecone, RAG pipelines, Prompt Engineering
Automation: n8n, Zapier, custom workflow engines
Infrastructure: AWS (EC2, S3, Route 53), Docker, CI/CD, Nginx, PM2
PROOF
8+ years building production software. Currently engineering an AI voice receptionist platform (real-time STT, LLM orchestration, TTS, telephony integration), not a wrapper, a full AI product. Multiple SaaS platforms built and maintained end-to-end (see portfolio: Avana, Well Send, client projects). Top-rated on Upwork with 100% Job Success Score.
WHY CLIENTS HIRE ME
