Web Developer with AI/ML expertise
Category : Web development
I help startups and SMBs ship production AI systems—not demos—including RAG chatbots, support and lead-generation bots, and full-stack web apps with Python and React.
What I deliver
1) RAG & knowledge chatbots
Custom bots trained on your documents, help center, or internal knowledge base. Answers include citations, guardrails, and fallback to human handoff when needed. Ideal for support deflection, onboarding, and internal search.
2) Website & customer-facing AI
Embeddable chat widgets and in-app assistants that qualify leads, answer product questions, and integrate with email/CRM (webhooks, Zapier, HubSpot-style flows).
3) AI inside your product
Search, summarization, and Q&A embedded in dashboards, admin panels, and portals—built with FastAPI or Node backends and React/Next.js frontends.
4) Document & data automation (Python)
Ingestion pipelines for PDFs and unstructured content, structured outputs (Excel/CSV/JSON), and auditable reasoning for QA/review workflows.
How I work
Short discovery call or async brief
Working prototype in 48–72 hours (where scope allows)
Iteration toward production: auth, monitoring, deployment, handover docs
Clear fixed-price Phase 1 milestones before large builds
Tech stack
Python (FastAPI), Node.js, React/Next.js, PostgreSQL, OpenAI & Anthropic APIs, LangChain, vector stores (pgvector, Pinecone), Docker, REST APIs, streaming where needed.
Privacy & quality
Your data is processed via APIs with no training on your proprietary content (per provider policy). I version prompts, log tool traces, and design for maintainability so your team can own the system after launch.
Engagement types
Hourly for ongoing product work
Fixed-price POCs and milestones for defined scope
Consultation for architecture and stack choices
Best fit
Teams that want a senior builder who ships end-to-end: backend, integrations, frontend surfaces, and deployment—not slide decks or notebook experiments.
Not a fit
Entry-level tutorials, $50 “clone ChatGPT” scopes, pure WordPress/theme work, or roles requiring RTSP/video surveillance or foundation-model fine-tuning as the primary deliverable.
Share your site/app, data sources, and what the AI should do—I’ll reply with a practical plan and a Phase 1 quote.
