WooCommerce PHP Cloudflare

Trading automation systems

Python PowerShell MetaTrader 5 ...
Designed and operated long-running algorithmic-trading systems with strict risk rules: Python and PowerShell orchestration, large backtesting and optimization harnesses, monitoring watchdogs with email alerting, and Playwright-based data scrapers. Reliability-focused automation where correctness and fail-safes matter.

RAG document Q&A prototype

Cloudflare Workers bge-m3 reranker ...
Retrieval-augmented question answering, fully server-side: overlapping chunking, multilingual bge-m3 embeddings (1024-d), cosine top-k retrieval, bge-reranker-base cross-encoder reranking, and grounded generation with mistral-small-3.1 and inline citations. It refuses to answer when the corpus does not contain the answer. Every pipeline step is exposed in the UI, and users can paste their own document to query it.

Profil

Full-stack developer specialising in AI/LLM integrations, working daily with the Claude and OpenAI APIs. I take projects end to end and solo: from clarifying an unclear brief, through the data model, backend and frontend, to tests and deployment, and I deliver working live products rather than slideware. Over 50 production deployments in the last month and 2+ years of commercial development. Comfortable with ambiguous scope; a disciplined AI-assisted workflow gives me speed without skipping tests, migrations or review on critical paths such as authentication, payments and personal data.


CORE SKILLS

  • Frontend: React, Next.js, responsive UI, design-system-driven layouts
  • Backend: Node.js (Express / Fastify), Python (FastAPI); REST API design; auth (JWT, OAuth, sessions)
  • AI / LLM: Claude and OpenAI APIs (daily), server-side integration, streaming, cost/rate control, moderation; RAG (embeddings, cosine retrieval, cross-encoder reranking); Cloudflare Workers AI
  • Cloud / DevOps: Cloudflare Workers/Pages, domains/DNS/email routing; Git and GitHub; deploy-from-Git; staging/production separation; env-based secrets; Docker (working knowledge)
  • Integrations: Third-party APIs (payments incl. Stripe concepts/sandbox, email/SMS, analytics), Playwright automation and scraping
  • Practices: SPEC-first delivery, GDPR-aware data handling, security basics, unit and manual testing


HOW I WORK

Ask clarifying questions first, then write a half-page SPEC (what I build, what I deliberately do not, and how we verify "done"), agree it, ship the smallest live version early, test, and deploy. I give estimates as ranges with conditions and flag any slippage the moment I see it, not on the deadline. On critical paths I never let AI "just write it": I read, test and understand every change.


WORK EXPERIENCE

06/2023 - present

Role: Freelance Full-Stack Developer (self-employed) 

Customer: Remote - web development, AI/LLM integrations, e-commerce, automation


Tasks:

Independent commercial development for clients and own products: requirements clarification, SPEC-first scoping, backend and frontend implementation, testing, deployment and operation. 50+ production deployments in June-July 2026 alone, backed by a semi-automated intake and delivery pipeline.
