Williams C.

I'm Williams, a full-stack developer and technical consultant with 10+ years of experience building across a wider range than most developers you'll meet on here. I ship production software in four areas: modern web applications, AI/SaaS platforms, enterprise low-code systems, and algorithmic trading tools. That range isn't a lack of focus - it's the result of working with founders, agencies, and enterprise teams whose problems rarely fit neatly into one stack. Whether you need a landing page that converts, a multi-tenant RAG platform architected from scratch, or an MT5 Expert Advisor that mirrors trades between brokers, I can scope it, build it, and hand it off clean. What I build: Web / Mobile product development - Marketing sites, SaaS dashboards, Digital Podcast / Radio Streaming and internal tools with Next.js, React, Tailwind CSS, and Hugo. AI & SaaS platforms - Multi-tenant RAG systems, document ingestion pipelines, vector search (ChromaDB, pinecone, pgvector), and LLM integrations (OpenAI, Claude) Enterprise systems - Microsoft Power Platform (Model-Driven Apps, Dataverse, Power Automate) for real estate, fleet, and operations workflows Algorithmic trading - PineScript indicators & strategies for TradingView, MQL5 Expert Advisors for MT5, and cross-broker trade copiers (Exness to FTMO, etc.) Technical consulting - Architecture reviews, scope-of-work documents, ERDs, and commercial proposals for enterprise projects Tech I work with: - Frontend: Next.js, React, Vue, Tailwind CSS, Hugo, TypeScript, HTML, CSS, Javascript. - Backend: Python (FastAPI, SQLModel), Node.js, PostgreSQL, MongoDB, NeonDB, - AI/Data: ChromaDB, pgvector, OpenAI & Anthropic APIs, embedding pipelines, RAG architecture - Enterprise: Microsoft Power Platform, Dataverse, Power Automate, Power BI - Trading: PineScript v5, MQL5, MetaTrader 5, FIX/broker APIs - Cloud & DevOps: Azure, Vercel, Netlify, Git, CI/CD Why clients keep coming back: - I think in systems, not just tickets - you'll get architectural input, risk flags, and honest scope pushback when it matters - Clear written communication and documentation - ERDs, SOWs, and READMEs that your next developer can actually pick up - I ship. Ranges from a 2-week MVP to multi-month enterprise engagements (including $50k+ proposal scopes) I work comfortably across time zones with teams in the US, EU, and Africa If you've got a project - whether it's a fresh MVP, a stalled build that needs rescuing, or a technical decision you want a second opinion on - send me a message with a few details and I'll reply within a few hours.
