Dev Ops Team We had an excellent experience working with this Softermii. Their AI team was highly professional, communicative, and delivered everything on time. They quickly understood our requirements and provided a scalable solution. It really felt like they were an extension of our own team.

Vienna, Austria - 10:54 pm local time
6+ years building full-stack web products that ship on time and hold up in production. I work across the full stack, from React and Next.js interfaces to Node.js and Laravel backends, and I take ownership of the whole thing.

What I work on:
Web applications and SaaS platforms in React, Next.js, and TypeScript. Backend services, REST APIs, and GraphQL in Node.js, Express.js, and Laravel. JavaScript and TypeScript across both frontend and backend. Third-party integrations and webhooks: Stripe, HubSpot, Salesforce, Twilio, and custom CRM and payment APIs. Real-time features with WebSockets and server-sent events. CI/CD pipelines, automated testing, and deployment on AWS, Docker, and GitHub Actions. Performance optimization and security hardening built in from the start.

Core stack:
JavaScript, TypeScript, React, Next.js, Node.js, Express.js, Laravel, PHP, PostgreSQL, MySQL, MongoDB, REST APIs, GraphQL, WebSockets, AWS, Docker, GitHub Actions, Vercel, Tailwind CSS, Redux, Zustand

Good fit for: SaaS products, internal tools, API integrations, marketplace platforms, e-commerce, web applications, product rebuilds and migrations, startup MVPs.

I work within the Softermii team, a full-cycle software and AI development company with 100+ products delivered across healthcare, fintech, real estate, logistics, and e-commerce. We also use Apex, our internal delivery framework, which keeps scope tight, prevents rework, and makes delivery timelines predictable.
