Most "AI" projects break the same way. The demo works, then real users arrive and the chatbot hallucinates, the agent loops forever, retrieval returns garbage, and the backend falls over. The model was never the hard part. The engineering around it is. That's what I do. I'm an AI Engineer who builds LLM-powered products that actually hold up in production, not demos that fall apart the first time a real user touches them. I've shipped an LLM diagnostic assistant for a US-based manufacturer, semantic search over a community platform, and a real-time AI scoring engine running on live data. AI that does a job, with the retrieval, grounding, and orchestration that make it reliable. 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭𝐬 & 𝐋𝐋𝐌 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 Autonomous and tool-using AI agents, multi-step workflows, and LLM-powered assistants that take real actions, call APIs, query your data, and make decisions. Built with function calling, tool use, and orchestration that stays controlled instead of spiraling. Powered by Claude, GPT, and open-source models. 𝐀𝐈 𝐂𝐡𝐚𝐭𝐛𝐨𝐭𝐬 & 𝐂𝐨𝐧𝐯𝐞𝐫𝐬𝐚𝐭𝐢𝐨𝐧𝐚𝐥 𝐀𝐈 Production chatbots and assistants grounded in YOUR data, customer support bots, internal copilots, and domain experts that answer accurately because they're backed by real retrieval, not guesswork. Streaming responses, memory, and conversation flows that feel natural. 𝐑𝐀𝐆 & 𝐒𝐞𝐦𝐚𝐧𝐭𝐢𝐜 𝐒𝐞𝐚𝐫𝐜𝐡 Retrieval-Augmented Generation that grounds LLM answers in your documents, manuals, and knowledge bases, so responses are accurate and traceable instead of hallucinated. Vector embeddings, semantic search, and pgvector pipelines built for relevance and speed. Plus prompt design and evaluation to keep quality measurable as you scale. 𝐀𝐈 𝐁𝐚𝐜𝐤𝐞𝐧𝐝 & 𝐀𝐏𝐈𝐬 The production engineering most AI freelancers skip. FastAPI and Django backends, REST APIs, JWT/OAuth2 auth, async pipelines with Celery, Redis, and Kafka, and clean data models, so your AI features run fast, securely, and at scale. 𝐀𝐈 𝐒𝐚𝐚𝐒 & 𝐌𝐕𝐏 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 End-to-end AI products from idea to launch. Database design, multi-tenancy, Stripe billing, AWS and Docker deployment, and React/Next.js frontends when you want full-stack delivery. The whole foundation your AI product needs to ship fast and scale.

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. ContentDrafter: AI SaaS platform for automated content generation with subscription-based access. Built the AI integration layer, prompt workflow system, authentication, and scalable backend APIs. Optima CRM: Custom CRM for sales pipeline and customer management. Delivered dashboards, lead management, role-based access control, and reporting end to end. Qreates: AI-powered SaaS platform converting product images into interactive 3D visualizations. Built the end-to-end pipeline: image workflows, AI processing, rendering integration. Market Intelligence Pipeline : Python data pipeline surfacing pricing and inventory signals across marketplaces for automated sourcing decisions. Brand Protection System: Automated data acquisition tool paired with an AI-driven analysis dashboard for continuous competitive monitoring. Tech Stack Python • FastAPI • Flask • 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.
