Full Stack SaaS Developer | AWS Cost Optimization | Scalable Architecture
Your SaaS roadmap is slipping. Features take longer than expected. Technical debt is growing. And hiring the wrong engineers burns months of runway.
Whether you're building an AI product, scaling after MVP, or fixing a system that’s becoming hard to maintain I step in as a CTO-level engineering partner to help you ship reliably.
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.
