Project details

Most small businesses don't need enterprise software — they need one clean, professional tool that does the specific job in front of them. That's what this is. I build and deploy a real web application, branded to you, with one of your key business processes automated behind it — intake, processing, and results, all in one place your team (or your customers) can actually use.

You get a live app on your own accounts, the source code, and a process that's automated instead of manual. I handle the build, the AI, and the deployment. You get something tangible and professional you can put to work immediately.

Built on a proven, modern stack — a Next.js application with Supabase handling your database, authentication, and storage, deployed on Vercel. This is a focused, productized build on that stack, which is exactly what keeps it fast, reliable, and affordable. It's not a from-scratch custom backend or a bespoke database project — it's a clean, well-architected app that does your specific job and is yours to own.

I keep the scope clear and the price fixed so there are no surprises. If you need something bigger down the line, we can plan that separately — this gets you live, fast.

Many teams bolt an API call onto existing software and call it AI. Then real users arrive: costs balloon, outputs hallucinate, and there's no visibility into why. Production AI requires a different discipline — grounding, observability, systematic evaluation — not just an API call to a thin LLM wrapper.

That discipline is what I'll bring to your team. I can tell you exactly what type of AI tooling you require for your specific solution. I can help you determine the technical feasibility of your AI project 𝘣𝘦𝘧𝘰𝘳𝘦 you spend valuable time and money pursuing it. I can teach your team how to use agentic development to build software quickly and confidently. In short, I'm here to make sure you and your team get what you need from AI technology.


𝗣𝗿𝗼𝗳𝗶𝗰𝗶𝗲𝗻𝗰𝗶𝗲𝘀

✅ AI Pipeline Architecture: hybrid RAG, agentic tool-calling loops (LangGraph), structured output enforcement, prompt injection defense, PII redaction, quantization

✅ AI Evaluation: LLM-as-judge frameworks, test set design, deterministic checkers, RAGAS retrieval metrics, regression tracking

✅ AI Optimization: prompt engineering, retrieval tuning, context compression (LLMLingua), caching strategy, cost/latency tradeoff analysis, experiment tracking (MLflow)

✅ Observability: OpenTelemetry tracing, Prometheus metrics, Grafana dashboards, Loki logging, Jaeger

✅ LLM Providers & Models: Anthropic, OpenAI, Gemini, self-hosted GGUF quantized models, Llama Guard

✅ Frontend: React, Next.js, TypeScript, Tailwind, Redux, SSE/WebSocket streaming

✅ Backend: Python (FastAPI, Celery), Node.js, Go

✅ Databases: PostgreSQL, Pinecone, Qdrant, Redis, MongoDB, Firebase

✅ Cloud & DevOps: AWS, GCP, Azure, Docker, Kubernetes, CI/CD


𝗪𝗵𝗮𝘁 𝗬𝗼𝘂 𝗖𝗮𝗻 𝗘𝘅𝗽𝗲𝗰𝘁

- A pipeline you can trust in production — not just one that demos well. I instrument observability, build eval frameworks, and optimize systematically so you know what's working, what isn't, and why.

- Full-stack ownership — I can own the AI layer, the API, and the frontend. No coordination tax between specialists; one engineer who sees the whole system.

- Communication that matches your pace — async-first with structured updates, or high-touch with regular syncs. I adapt to how your team works, not the other way around.

- Clarity from ambiguity — I have built production systems from partially-defined requirements many times. If you know the problem but not the solution, that's exactly the engagement I'm built for.

If your AI project needs to actually work — reliably, efficiently, and at a cost that makes sense — let's talk. Schedule a no-obligation call to discuss your project in detail.

Steps for completing your project

After purchasing the project, send requirements so Joe can start the project.

Delivery time starts when Joe receives requirements from you.

Joe works on your project following the steps below.

Revisions may occur after the delivery date.

Alignment (Day 1–2)

I confirm the screens, the workflow, and the integration in writing before any build begins — so we're locked before I start.

Build

I develop the app and the automation on a proven foundation.

Review the work, release payment, and leave feedback to Joe.
