International Teams
Production Systems
Anonymized DeFi, FinTech, and blockchain frontend work — the challenge, the approach, and the outcome. Client names are removed under NDA.
FinTech · DeFi · Blockchain
A modular rewards module for a live FinTech platform that let two on-chain reward providers run in parallel without touching the existing production flow.
Blockchain Analytics
One dashboard unifying wallet balances, staking positions, and protocol data from multiple independent sources without sacrificing speed.
Enterprise Web3
Refactoring a fast-growing Web3 product's frontend to remove duplicated logic and support faster, more consistent feature delivery.
Capabilities
Production frontend systems for Web3, DeFi, blockchain, and financial products — not prototypes.
Wallet integrations, staking, rewards, token migration, DeFi positions, and transaction experiences.
Portfolio dashboards, analytics platforms, data-intensive systems, and financial workflows.
On-chain data, RPCs, APIs, subgraphs, smart-contract interactions, and multi-chain applications.
Scalable React/Next.js architecture, caching, performance optimization, reliability, and maintainability.
My Process
A clear, structured process so you always know what's happening and what comes next.
A free 30-minute call to align on product goals, users, timeline, and budget — no commitment required.
A written proposal covering deliverables, timeline, and price within 24 hours. No surprises.
Focused sprints with a staging link early, so you review real progress instead of a final reveal.
Production deployment, documentation, and a clean handoff for your team and next developer.
Verified Upwork reviews from clients on Next.js, Web3, and frontend projects — focused on communication, code quality, and delivery.
FAQ
Everything clients usually ask before starting a project.
Both — it depends on what works best for your project. For well-defined projects (a landing page, a dashboard with clear scope), I prefer fixed price so you know exactly what you're paying upfront. For ongoing work or projects with evolving requirements, hourly at $40–65/hr makes more sense. We'll agree on the structure before anything starts.
Landing pages and marketing sites: 3–5 business days. Web3 dashboards and DeFi tools: 1–2 weeks. Full product frontends from Figma designs: 2–4 weeks. These are typical timelines for focused, well-scoped projects. Rush delivery is possible for an additional fee.
I'm based in Islamabad, Pakistan (UTC+5). I regularly work with clients in the US, UK, Europe, and the Gulf. For async work, timezone rarely matters. For calls, I accommodate early morning or evening slots that overlap with US and European business hours.
Yes, always. Every project includes Vercel deployment, custom domain connection, DNS configuration, SSL verification, and environment variable setup. Your site will be fully live and production-ready.
Yes, 100%. All code is yours. I push everything to a GitHub repository in your account. No lock-in, no licensing fees, no strings.
If you're building a DeFi platform, wallet experience, blockchain dashboard, or financial product and need someone who understands both product UX and frontend infrastructure, let's talk.
