My Process

01

System Design & Data Modeling

I define the database schema, API contracts, authentication flow, and infrastructure requirements before writing any application code.

02

Backend & API Development

I build the Django backend with business logic, API endpoints, background tasks, and admin tooling — deployed to staging with seed data for testing.

03

Frontend & Integration

React frontend wired to the API with state management, real-time updates, and responsive layouts — tested against the live backend on staging.

04

Load Testing & Production Deploy

Stress testing, security audit, monitoring setup, and production deployment with CI/CD pipeline, backups, and runbook documentation.

Frequently Asked Questions

What tech stack do you use for web applications?+

I primarily build with Django + React for full-stack applications, and Next.js for content-heavy or SEO-critical platforms. Django handles the backend API, authentication, and business logic while React provides the interactive frontend. For databases I use PostgreSQL in production with Redis for caching and Celery for background tasks.

Can you build a SaaS platform from scratch?+

Yes — I've built multi-tenant SaaS platforms with subscription billing, role-based access, usage tracking, and API layers. Sellanto is a full SaaS product I architected with AI-powered features, multi-tenant data isolation, and Stripe subscription management handling real paying customers.

How do you handle mission-critical systems that can't fail?+

I build with redundancy, automated failover, and extensive error handling. The KOICA election management system I built processed real government elections with zero failures — it included voter verification, real-time result tabulation, audit trails, and offline-capable polling station modules.

Do you build admin dashboards and internal tools?+

Yes. I build custom admin panels with role-based permissions, data visualization, bulk operations, and real-time updates. These are purpose-built for your workflow — not generic admin templates — with exactly the views, filters, and actions your team needs to operate efficiently.

How do you handle deployment and hosting?+

I deploy to VPS (DigitalOcean, AWS EC2), containerized environments (Docker), or serverless platforms (Vercel, Railway) depending on the project. Every deployment includes CI/CD pipelines, environment management, SSL, automated backups, and monitoring so the system runs reliably after handoff.
