Complex Web Applications
Production web apps when templates stop working.
Dashboards, SaaS products, internal tools, real-time systems.
There's a point where no-code stops being enough. Your product needs real-time updates, complex state, custom flows, or performance the templates can't give you. That's when you need code — but code built to survive past its launch week.
I build web applications where the frontend actually has to work: interfaces used every day by real people, handling real data, at scale that matters.
What is included
- SaaS Products — multi-user apps with auth, roles, complex state that stays consistent across tabs and sessions.
- Internal Tools & Admin Panels — CRMs, moderation panels, ops dashboards. Reliability first, performance second, design third.
- Real-time Systems — chats, live dashboards, collaborative interfaces, video/voice. WebSocket, SSE, WebRTC — I've shipped all three in production.
- Data-heavy Interfaces — tables with 10K+ rows that don't freeze, live-updating charts, filters that don't break the URL.
- Integration with the services your business relies on
- Deployment and post-launch support
