Node React Python AWS - Full-stack AI developer
Strong technical understanding and very solution oriented. All requirements were handled with confidence and clarity. Communication was efficient, and technical decisions were explained clearly when needed. The project was completed successfully, and I would gladly collaborate again.

Full-stack web developer ( Node React Python AWS )
An absolute pleasure to work with. Heās not only technically skilled but also highly communicative and reliable and always quick to respond, open to feedback, and focused on getting the job done right. Itās clear he takes pride in his work, and it shows in both the quality of the code and his proactive problem-solving approach. I wouldnāt hesitate to hire him again or recommend him to anyone looking for a top-notch developer. Thanks again

š¤ WHAT I BUILD
AI agents and agentic workflows. An agent that reads a request, decides what to do, calls the tools it needs, and reports back. Multi-step chains with guardrails, retries, and logs you can actually read when something goes wrong.
AI automation and workflow automation. Automation across the systems you already pay for: CRM, email, chat, spreadsheets, databases, payment and messaging providers, internal APIs. A visual workflow builder when you want to own and edit the flow yourself, and a custom Python or Node service when the logic outgrows one. Either way you get the map of what runs, when it runs, and what happens when a step fails.
LLM chatbots and assistants. Support bots, internal knowledge assistants, and lead qualification bots wired into your live data instead of a frozen FAQ page.
RAG and semantic search. Ingestion, chunking, embeddings, vector search, and retrieval that returns the right passage instead of a confident guess. The model provider sits behind one interface, so a price change or a model deprecation is a config edit and not a rebuild.
APIs and integrations. REST and GraphQL services, webhook plumbing, third party payments and messaging, plus the unglamorous reliability work: idempotency, rate limits, queues, retries, alerting.
Dashboards and internal tools. When automation starts making decisions, a human needs to see them. I build the admin panel, the analytics view, and the override button.
š¦ WORK I CAN POINT TO
A custom call center dashboard and lead management tool, integrated with GoHighLevel.
An AI-driven SaaS platform with chatbot personas over voice and text chat.
A SaaS product on OpenAI for generating test and QA data.
A reverse auction web application with the bidding logic built from scratch, on top of a client's existing site. Closed at 5.0.
A full-stack AI build on Python, Node, React and AWS, 948 hours on one contract. Closed at 5.0, with the work called strong technically and very solution oriented.
āļø HOW I WORK
One engineer, whole stack. Architecture, backend, frontend, integrations, deployment. You are not coordinating three specialists and translating between them, and there is no seam where a bug turns into somebody else's problem.
Scope before code. Show me the real process: the inputs, the edge cases, the decision you want made. Then I tell you what an LLM should handle, what plain code should handle, and what a person should still approve. A model put where a plain rule belonged is the most expensive way to build this kind of system.
Ship in slices. You get a thin path running end to end on your real data first, then depth on top of it. Progress you can click, not a status update.
Measure before you trust it. A prompt is not a deliverable. I would rather agree a set of real examples with you up front, including the ones you expect it to get wrong, and show you how the build handles those before it goes anywhere near your customers.
Own it after launch. Structured logging, error handling, visible cost per run, and a handover your own developers can pick up and change.
š§° STACK
Python and Django, Node.js, JavaScript, React and Next.js, Vue.js. LLM, machine learning and artificial intelligence work, embeddings, vector search and RAG pipelines, chatbots and AI agents, workflow automation. MySQL and relational data modeling. REST, GraphQL, webhooks, queues, API integration. Architecture and deployment on AWS for everything I ship.
šÆ WHO THIS FITS
Founders with a manual process quietly eating a full time salary in staff hours ā the invoice that gets retyped into two systems, the report somebody rebuilds every Monday. Agencies who sold an AI feature and now need someone who can ship it. Operations teams copy pasting between four tools all day. Product companies who want AI inside a working product without turning the roadmap into a science project.
š§ WHO IT DOES NOT FIT
If you want a prompt pasted into a no code tool and called a product, I am the wrong hire and I will say so in the first reply. If you want something that runs every day, survives bad input, and does not embarrass you in front of your customers, that is the work I do.
ā WHAT YOU GET
A working system and source code you own, with no dependency on me to keep it running. If you decide to move it in house or to another developer later, that is a handover, not a rescue.
š¬ HOW TO START
Capacity for a new build now, 30+ hours a week. Send me the process you want automated. I will come back with how I would build it, where I think it breaks, and what it costs to run.
