About this gig

Need a custom backend or API integration that works reliably in production not just a script? I build and integrate backend systems using Python, FastAPI, and Django for businesses that have outgrown no-code tools.

What I build:

  • REST API design and development (FastAPI or Django REST Framework)
  • Third-party integrations (payment gateways, CRMs, SaaS tools, internal systems)
  • Webhook handling and authentication (OAuth, API keys, JWT)
  • Database design and optimization (PostgreSQL, MySQL)
  • Python automation scripts and scheduled jobs
  • Bug fixes and performance optimization on existing code
  • Clean documentation (OpenAPI/Swagger) so your team isn't stuck guessing later

I scope every project before starting you'll know what's being built and how it's tested, with no surprises on delivery day.

Why work with me: computer science background, clean tested code, clear scope before any work starts.


Message me what you're trying to build, fix, or connect, and I'll tell you the cleanest way to do it.

Hi, I'm Jessy. I help businesses automate manual processes and turn traffic into paying customers. I work in three areas: AI automation (n8n, Make, Zapier, AI agents for lead routing & follow-ups), conversion rate optimization (funnel, landing page & checkout audits), and backend/API development (FastAPI, Django, Python). Final-year Software Engineering student building production systems, not tutorials — background in React, Next.js, and hands-on funnel/marketing experience. Message me what you're trying to automate, fix, or build, I'll tell you exactly what it takes.
