Python • AI Integration • AI Automation • FastAPI • Flask • Django • Backend Development • SaaS Development • MVP Development • AI Agent Development • Prompt Engineering • N8N • Zapier • Data Engineering • Business Process Automation I build production-grade SaaS platforms, AI-integrated products, and business automation systems for founders and CTOs who need an engineering partner: not a task executor. Over 10+ years and 190+ completed projects, I've learned that the real value isn't writing code on request: it's understanding the business problem well enough to make the right technical call, then owning that decision through to production. What I Deliver AI Integration & Automation : OpenAI and Claude API integration with proper prompt engineering, AI agent workflows for multi-step task automation, plus process automation built in N8N and Zapier that removes manual steps from a client's process. Backend & SaaS Development : Production-grade backends built primarily with Python (FastAPI, Flask, Django) full SaaS products and MVPs built end to end. Also comfortable working in Ruby on Rails when a client's existing codebase or team calls for it. I design APIs for real production load authentication, async processing, clean data models. Business Process Automation & Data Engineering, Python-based ETL pipelines and data acquisition systems that turn scattered information into structured, usable business intelligence collection, cleaning, transformation, delivery into a database or dashboard your team can use. Chrome Extension Development, Custom browser extensions for automation, data capture, and workflow tools, shipped and used in production. Proven Results Euka AI: AI-powered CRM for social commerce. Built core platform features including dashboard workflows, creator discovery and outreach automation, campaign management, and API integrations.

Brand Protection System: Automated data acquisition tool paired with an AI-driven analysis dashboard for continuous competitive monitoring. Tech Stack Python • FastAPI • Flask • Django • Ruby on Rails • N8N • Zapier • React • Next.js • Node.js • Express • MongoDB • OpenAI API • Claude API • PostgreSQL • AWS • REST APIs • Selenium • Scrapy • Playwright How I Work I start by understanding the business problem before touching the stack — what the automation needs to solve, what the AI feature needs to do for the user, what "done" looks like for the MVP you're asking for. I scope clearly, flag risks early, and build for where your product is going in six months, not just this week's ticket. Why Clients Hire Me Clients consistently cite fast communication, daily progress updates, and code that doesn't need a second developer to fix it later. On more than one project, I've flagged a requested feature that would have caused problems at scale and proposed an alternative before writing a line of code. Let's Build If you need a Python developer who can integrate AI meaningfully, automate a manual process, or build your SaaS MVP end to end, let's talk about what you're building.

What I deliver for clients: - Rails version upgrades (Rails 4/5 to 6/7/8) with zero downtime and full test coverage — including legacy migrations like Paperclip to ActiveStorage - Performance optimization — up to 40% speed gains on production systems through query tuning, caching, and background jobs - Legacy & undocumented codebases stabilized by a senior hand, with RSpec/Capybara coverage so you can ship with confidence - SaaS backends from MVP to production-grade (Ruby on Rails, PostgreSQL, Sidekiq, Redis, Heroku, Docker) - Rails APIs integrated with React / Next.js frontends and third-party services (Stripe, PagerDuty, StatusPage, OpenAI) Proof it works: - Rebuilt StatusGator's Rails platform over 2 years — became their most prolific contributor (2,000+ hours, $60K+). "He ended up becoming the most prolific contributor to our project." — Colin B., StatusGator - Upgraded a client's app from Rails 4 + Paperclip to a modern stack — "Raza was great!" (5.0 stars) - 21+ completed jobs, the majority rated 5.0 stars, with repeat clients spanning 1,000+ hour engagements I work full-stack across Node.js, Next.js, and React when a project needs it — with the same clean architecture and testing discipline I bring to Rails.
