Senior Flutter (GetX) Engineer: Refactor & Upgrade Property App, Feature Parity + Tests
Keval did an outstanding job rebuilding our production Flutter app using Clean Architecture and migrating integration logic into modular cloud functions. He maintained full feature parity while improving performance, structure, and maintainability. Great communication, strong problem-solving, and highly professional throughout. A rare developer who understands architecture, not just UI. Highly recommended and will rehire.

I work with founders, CTOs, and product teams to stabilize, optimize, and scale SaaS platforms so they perform reliably as the business grows.
I help SaaS founders and growing startups scale products without letting infrastructure costs, performance issues, or weak architecture slow growth.
Most teams reach a point where the MVP works but the system starts showing cracks:
• AWS costs keep increasing
• APIs become slow under load
• Bugs and technical debt slow delivery
• Architecture struggles to scale
That’s where I step in.
What I Help With
⚙️ SaaS Architecture & Scaling
Design and improve systems built for growth scalable backend architecture, clean APIs, optimized databases, and infrastructure that holds under real traffic.
💰 AWS Cost Optimization
Audit cloud infrastructure, identify waste, and reduce unnecessary spend while improving reliability and performance.
⚡ Performance & Reliability
Fix bottlenecks, slow APIs, database issues, memory leaks, and stability problems before they become expensive.
🤖 AI Features & Automation
Implement practical AI workflows, automations, and integrations that improve user experience and operational efficiency.
Tech Stack :
Frontend: React.js, Next.js
Backend: Node.js, Python (Django, Flask)
Database: PostgreSQL, MongoDB, Firebase, Supabase
Cloud & DevOps: AWS, Docker, Kubernetes, CI/CD
Why Clients Work With Me
✔️ Hands-on senior engineering (I write the code)
✔️ Clear communication & fast execution
✔️ Product and business focused, not just technical delivery
✔️ Built for long-term scale, not short-term fixes
If your SaaS is growing and you're facing performance, scaling, or cloud cost challenges, send me a quick overview of your stack or current bottleneck.
I’ll tell you what I’d investigate first and where the biggest improvement opportunities usually are.
