Marketing Site Design + Logo for Interpretis (B2B SaaS)
Working with this team was an amazing experience from start to finish. They have handled all things UI/UX like our SaaS marketing site and logo design with a level of professionalism and quality that made the process feel effortless on my end. Communication was clear from Maria who kept the project on track with daily development reports, Loom walkthroughs, and proactive design suggestions that showed they genuinely cared about the results. The team took the brand references and translated them into a clean, modern design that exceeded expectations. They were receptive to feedback, quick to iterate, and always offered thoughtful solutions when questions came up. Highly recommend for anyone looking for a design team that delivers quality, consistency, and peace of mind.

⭐ Top Rated Plus React developer
📅 6+ years of experience Full-stack development
📦 70+ projects delivered
⏱️ 5,000+ Upwork hours
🔁 ~70% returning clients
A full stack developer and React developer with 6+ years of experience building fast, scalable, and secure web applications from MVP to production scale — a proven track record of reliable, high-quality delivery for startups, founders, agencies, SaaS companies, and growing businesses.
🏢 Multi-tenant SaaS & B2B platforms
Strong background in multi-tenant SaaS and B2B platforms: secure, role-based systems with custom workflow logic, OWASP-compliant authentication, RBAC, and full Stripe billing (Checkout, Subscriptions, and Connect) — built to scale reliably, reduce manual operations work, and keep subscription billing accurate. This aligns well with SaaS, dashboard, admin panel, and B2B platform projects.
🤖 AI-powered products
Experienced in AI-powered products: RAG pipelines, embeddings, semantic search, and prompt engineering with the OpenAI and Anthropic APIs. I build AI SaaS, chatbots, and automation tools with real-time features, streaming responses, and offline-ready PWAs — designed to lower response latency and improve reliability for end users. A strong fit for AI SaaS, automation, and integration projects.
🛒 Web apps, marketplaces & e-commerce
As a web developer, I build two-sided marketplaces, e-commerce platforms, booking and scheduling systems, real-time chat and messaging, analytics dashboards, internal tools, and landing pages. Comfortable with complex features like authentication flows, payment processing, real-time data handling, and third-party API integrations.
⚡ Next.js, performance & SEO
As a Next.js developer, I work deeply with the App Router, Server Components, SSR, SSG, ISR, and Jamstack builds, plus API routes and middleware — builds that typically improve SEO, reduce time-to-interactive, and deliver faster load times. With strong front end developer experience, I optimize for Core Web Vitals, accessibility, and responsive, cross-browser interfaces — so your product ranks well and feels fast on every device.
🔌 Integrations & features
I implement OAuth and SSO, webhooks, payment gateways (Stripe and PayPal), Google APIs, calendar, email and SMS (SendGrid, Resend, Twilio), file uploads, PDF generation and exports, charts and data visualization, advanced search and filtering, notifications, and workflow automation with Zapier and Make.
🛠️ Tech stack
A JavaScript developer proficient in React, React.js, Next.js, Node.js, TypeScript, and JavaScript. Skilled in Express, NestJS, REST and GraphQL APIs, tRPC, Prisma and Drizzle, PostgreSQL, Supabase, Firebase, PlanetScale, and Neon. Frontend with HTML5, CSS3, SCSS, Tailwind CSS, Styled-Components, Shadcn/ui, Framer Motion, and GSAP; state and data with Redux, Zustand, React Hook Form, Zod, and TanStack Query. Cloud and DevOps on AWS (Lambda, S3, EC2, RDS, Cognito), Google Cloud Platform, Azure, Vercel, and Netlify, with CI/CD via GitHub Actions. Testing with Jest, Vitest, and Playwright; monitoring with Sentry; headless CMS with Sanity, Storyblok, Payload, and Contentful. As a React Native developer, I also build cross-platform mobile apps with React Native and Expo.
🔧 Beyond my core stack
Having worked across many different codebases, I'm also comfortable with and have worked with Python, PHP, Laravel, MySQL, MongoDB, Redis, WordPress, Java, FastAPI, jQuery, Gatsby.js, Remotion, and Web3 — so if your existing project mixes stacks, I can pick things up quickly, take over inherited code, and keep everything moving.
🎯 What clients hire me for
Clients hire me for scalable web applications, secure REST and GraphQL APIs, high-performance Next.js front-ends, clean and modern UI, responsive and intuitive dashboards, and reliable, production-ready SaaS — all built with maintainable, well-architected, and tested code. I work across industries including SaaS, B2B, fintech, e-commerce, healthtech, ed-tech, real estate, and online marketplaces, building everything from MVPs and internal tools to full-scale, multi-tenant products.
🤝 How I work
You get a reliable senior software developer who reads the brief carefully, asks the right questions, and communicates clearly. I recommend a pragmatic, scalable approach and ship clean, well-tested, production-ready code with strong ownership of performance, security, and maintainability.
💡 Whether you need a new product built from scratch, an MVP developer for a fast launch, a rescue of an existing codebase, or a long-term development partner, I'm here to help. Open to both fixed-scope MVPs and long-term product work.
