Project details
Are you tired of receiving spaghetti-code MVPs that collapse the moment real users hit them? I build production-grade full-stack applications that are architected to scale not just to demo.
I specialize in the "T3-Python" stack: FastAPI (Python) on the backend with Next.js 14+ (TypeScript) on the frontend, backed by PostgreSQL. Every project I deliver follows strict architectural principles the same patterns I use in a live enterprise SaaS platform serving B2B and B2C clients at scale. This isn't boilerplate. This is battle-tested code.
What's Inside Every Delivery:
• Auth System: JWT login/register, refresh tokens, role-based permissions with hierarchy. • REST API: FastAPI routes with full Pydantic v2 validation and auto-generated Swagger UI. • Database: PostgreSQL with SQLAlchemy ORM and Alembic migrations. • Frontend: Next.js 14 App Router with TypeScript and Tailwind CSS. • Deployment: Backend on Railway/Fly.io, Frontend on Vercel. Message me before ordering, I review every project to ensure I can deliver exactly what you need!

Your product is losing time and money to slow backends, brittle integrations, and data you still clean by hand. You already know it. I build the whole system so that stops.
Top Rated on Upwork with a 91% Job Success Score and a wall of 5-star reviews. Most freelancers own one layer — I own the frontend, backend, and data, so your project ships faster, costs less, and has no "that's not my layer" gaps.

🚀 WHAT I BUILD
🌐 Full-Stack SaaS Platforms
Production Next.js (App Router) + TypeScript frontends on FastAPI + PostgreSQL backends — auth, billing, RBAC, real-time dashboards, multi-tenant architecture. I currently lead full-stack development on a live influencer-marketing SaaS running campaigns across Instagram, TikTok, YouTube, Facebook & LinkedIn.
🤖 AI Integration & RAG Systems
OpenAI, Gemini & LangChain integrations that are grounded in YOUR data — RAG chatbots that don't hallucinate, AI agents that automate manual workflows, and pipelines that turn PDFs, CRM records, and raw text into decision-ready output.
⚡ Scalable FastAPI Backends
Async REST APIs with SQLAlchemy, Pydantic v2, Alembic migrations, auto Swagger docs, and Celery + Redis task queues — query-tuned and built to stay maintainable as you scale.
🕷️ Web Scraping & Data Pipelines
Scrapy / Playwright / Selenium scrapers that keep running when sites add bot protection. Delivered e-commerce, vehicle, and business-directory datasets (20k+ records) and B2B lead lists across the US, Canada & Europe — every data project rated 5 stars.
⚙️ Cloud & Async Infrastructure
Celery + Redis for heavy and scheduled jobs, containerized with Docker, deployed to the cloud with CI/CD. Runs in production, not just on my machine.

✅ HOW I WORK
I read your codebase before I touch it, ask the right questions once, and ship clean systems you can maintain after the contract ends. No handoff gaps, no surprise tech debt.
Have a backend, AI, or full-stack problem in mind? Message me — I'll give you a free feasibility review and a clear technical plan within 24 hours. No sales pitch, just a direct read on what it'll take.

Architecture & Scope Lock

Backend & API Core (FastAPI)
I build the FastAPI backend, set up JWT authentication, configure Alembic migrations, and generate the Swagger UI documentation.
