Sasja Laumann, design of Kajabi and website
Working with this team has been an outstanding experience from start to finish.
They designed and developed our new website exactly as we envisioned it. Their attention to detail, technical skills, and ability to translate our ideas into a clean, modern, and high-performing website exceeded our expectations.
Communication was always fast, professional, and transparent. They were proactive with suggestions, solved challenges quickly, and consistently delivered high-quality work on time.
What impressed us the most was their commitment to getting every detail right. They genuinely cared about the final result and were incredibly patient throughout the entire process.
We couldn't be happier with the outcome and would highly recommend them to anyone looking for a reliable, talented, and dedicated web design and development team.
Thank you for your excellent work-we look forward to working with you again on future projects!

For smaller projects, I work solo. For larger ones, I bring in my full-stack team โ we've collaborated for 5+ years, so you get the same reliability at any scale.
We are AI-first full-stack team of developers and designers who turn business ideas into production-ready SaaS platforms and B2B applications, delivered on schedule and within budget.
We use AI-powered development tools to speed up delivery and keep code quality consistent at every stage โ faster turnaround without cutting corners.

โญโญโญโญโญ "Outstanding full-service project delivery. They exceeded all expectations and delivered everything." โ verified Upwork client, 2025
Our clients include HIPAA-compliant healthcare platforms, B2B e-commerce systems, enterprise web applications, and custom SaaS tools built for thousands of concurrent users.
I'm the right fit for:
โ A SaaS founder moving from idea or prototype to a production-ready product
โ A B2B company that needs a custom platform, internal tool, or client portal
โ An e-commerce brand outgrowing your current setup (Shopify Plus, headless, or custom)
โ A startup or scaleup that needs a reliable technical partner, not just a developer
โ A company that needs HIPAA-ready, GDPR-compliant, or NDA-protected development (Master Service Agreement available on request)
DELIVERABLES:
โ๏ธ Full-Cycle Product Development
Architecture, UI/UX, backend, infrastructure, AI integration โ handled by my in-house team, not a chain of subcontractors. Built to handle growth from day one, so you avoid expensive rewrites later.
Stack: React, Next.js, Node.js, NestJS, Python, Django, PostgreSQL, AWS.
โ๏ธ AI Integration
OpenAI, Google Vertex AI, and custom ML pipelines built into your product โ chatbots, smart search, recommendation engines, process automation. AI as a real business feature, not a demo.
โ๏ธ B2B Web Platforms
Marketplaces, client portals, CRMs, LMS, internal tools โ systems that connect your users, data, and business processes in one place.
โ๏ธ E-Commerce (Shopify / WooCommerce / Headless)
Custom storefronts, Shopify apps, WooCommerce platforms, headless commerce with Hydrogen or Strapi. Built for conversion, performance, and ease of management.
HOW I WORK
I run every project through the same structured process: business analysis and requirements, a scoped proposal with timeline and budget, design in Figma with QA built into every development phase, launch, and post-launch support.
You get weekly updates, smooth communication, and a partner who treats your product like their own โ with full attention and commitment to success.
