Full Stack Developer for web, mobile, and SaaS.
const developer = { name: "Tarif Al Hasan", email: "tarifalhasanjs@gmail.com", role: "Full Stack Developer", stack: ["Next.js", "React Native", "Sanity"], status: "available",}Every tool in my kit is chosen for reliability at scale — the same technologies powering today's fastest-growing products.
Most developers start with the technology. I start with the outcome: the revenue a platform needs to generate, the hours a dashboard needs to save, the users an app needs to retain. Then I engineer backwards from there.
Since 2022, I've delivered scalable SaaS products, headless CMS platforms with Sanity, Payload, and Strapi, business dashboards, and cross-platform mobile apps for clients across five continents — from first-commit MVPs to systems serving tens of thousands of daily users.
Every build ships with performance, SEO, and accessibility treated as requirements — because a product that's slow, invisible to search, or unusable for some of your customers isn't finished.
From first prototype to production platform — a complete engineering partner under one roof.
Complex, data-driven platforms engineered with Next.js and React — built to stay fast and maintainable as your product grows.
From idea to launch-ready product in weeks. Authentication, billing, dashboards, and multi-tenancy — production quality from day one.
Editorial workflows your team will love, powered by Payload, Sanity, or Strapi — content modeling designed around your business.
Native-quality iOS and Android apps from a single React Native codebase, shipped through Expo with over-the-air updates.
Well-documented, versioned REST and GraphQL APIs with type-safe contracts — the reliable backbone your integrations depend on.
LLM-powered features that add real value: intelligent search, content generation, and automation woven into your product.
Core Web Vitals audits and fixes that move the numbers — faster loads, better SEO rankings, and higher conversion rates.
Transforming dated websites into modern, conversion-focused experiences — without losing your existing SEO equity.
Production platforms across commerce, Web3, healthcare, and education.
Full-Stack E-Commerce
A production-ready e-commerce platform built with Next.js, TypeScript, Prisma, and PostgreSQL — complete storefront, admin workflows, and scalable data layer.
Web3 Presale Platform
A dynamic Web3 platform for token presales, tokenomics, and community growth — wallet connect, CIN token sales, and live metrics in one experience.
Digital Solutions Website
A modern marketing site for innovative digital services — clean UI, fast performance, and a content-ready stack built for growth.
DeFi Platform
A decentralized finance platform for earning interest on crypto assets — built with a modern React and Next.js front end.
Healthcare Platform
A clinic management platform for appointments, patient workflows, and day-to-day operations — built for clarity and reliability.
EdTech · Headless CMS
A learning platform for skill development, powered by Next.js and Strapi CMS — structured content, clean UX, and scalable delivery.
Seven deliberate stages, refined over a hundred projects — so you always know exactly where things stand.
We start with your business goals, not the tech. I map out users, constraints, and what success actually looks like.
A clear roadmap with scope, milestones, and architecture decisions — so you always know what ships and when.
Interface design grounded in your brand. Every screen is intentional, accessible, and built to convert.
Clean, typed, well-tested code in short iterations. You see working software every week, not at the end.
Cross-browser, cross-device, and performance testing. Edge cases handled before your users ever find them.
Zero-drama deployments with monitoring, analytics, and SEO in place from the very first day in production.
Long-term partnership beyond launch — maintenance, new features, and a developer who already knows your codebase.
