I am an AI-Driven Full-Stack & Automation Engineer specializing in high-velocity product development and workflow architecture. By blending low-code platforms (n8n, Make) with modern AI development tools (Claude Code CLI) and scalable backends (VPS, Supabase, Pinecone, Redis), I build production-ready applications and complex automations that drive business growth. Instead of just linking basic API blocks, I engineer comprehensive ecosystems - from custom internal PWAs and secure RAG-based knowledge bases to full-scale web platforms. I leverage AI-accelerated coding to deliver full-stack solutions at a fraction of the traditional development time. What I bring to your business: First and foremost: you get rapid prototyping and the ability to turn those prototypes into a working product - as inside company or externally solution at the cost of a full team. I can help set up a department and infrastructure from zero, or I’m ready to join an existing team and help you grow as quickly as possible! And about me: • AI-Accelerated Full-Stack Development: Rapidly building web apps and frontends using advanced AI CLI tools (Claude Code, Cursor). • Advanced Workflow Orchestration: Designing complex, multi-layered logic inside n8n and Make with custom JavaScript data transformation. • Production Databases & Infrastructure: Architecting self-hosted environments using Docker, Supabase, Redis (state management), and vector databases (Pinecone). • Enterprise Automation: Saving thousands of operational hours by optimizing internal HR, procurement, and marketing structures. Technical Stack: • Automation & Orchestration: n8n (advanced code nodes), Make, Zapier, Webhooks, REST API • AI & Vector Search: OpenAI API, Claude API, Pinecone (RAG architectures), Embedding models • Backend, DB & Infrastructure: Supabase, Redis, PostgreSQL, Docker Compose, VPS hosting • Media & Frontend: BunnyStream, Progressive Web Apps (PWA) development via AI tools • CRMs & Tools: Pipedrive, Zoho CRM, Airtable, Notion, Manychat, Voiceflow

I’m Sufian, a Full-Stack Developer with 7+ years of experience across SaaS products, web apps, and backend-heavy systems. I work end-to-end: modern frontends, scalable backends, databases, third‑party integrations, and deployment. My focus is building systems you can actually run and extend, not throw away in six months. I build production-ready SaaS platforms and web applications, and when AI and automations are part of the roadmap, I integrate them in a practical, reliable way (RAG, chatbots, GHL workflows, n8n/Zapier) so they work with real data, real users, and real business processes. snipework Best fit if you’re building: - SaaS platforms with proper foundations (auth, roles, dashboards, admin tools, subscriptions, multi-tenant‑ready architecture). - Modern web apps (Next.js/React, MERN-style stacks) with clean REST/JSON APIs and scalable data models. - AI features inside real products (LLM integrations, assistants, workflow automation, content and data tooling). - RAG systems (chat with PDFs/docs/knowledge bases) with accurate retrieval, citations, and sensible guardrails. - AI chatbots for support, lead capture, and internal tools, embedded directly into your app or site. - Automation around your SaaS or CRM (GHL, n8n, Zapier/Make)—webhooks, APIs, syncing, routing, and logging. GoHighLevel, APIs & automations: - GHL setups and clean automations (pipelines, tags, custom fields, opportunities, workflows). - GHL API + webhook integrations with your own SaaS or backend (trigger-based actions, syncing, retries, deduplication, audit logs). - Multi-step workflows in n8n / Zapier / Make when “simple zaps” are not enough. - AI-assisted flows: lead qualification, smart routing, summaries, templated replies, and support-style assistants. Tech I work with regularly: - Frontend: Next.js, React, TypeScript. - Backend: Node.js, Express, Python. - Data: PostgreSQL, MongoDB, Supabase. - AI: OpenAI / GPT‑4 family, RAG, chatbots, AI assistants. - Automations & CRMs: GoHighLevel, n8n, Zapier/Make, webhooks and custom APIs. - DevOps: Docker, Vercel/Netlify‑style cloud workflows. How I work: - Product-first: I translate requirements into clear architecture, not just isolated features. - Clean engineering: readable code, clear boundaries between services, and maintainable patterns. - Production-minded: security, performance, logging, and monitoring are part of the delivery, not afterthoughts. - Communication: clear expectations, regular updates, and honest tradeoffs when scope or timelines change. If you share what you’re building (MVP, new SaaS, upgrades, AI features, or GHL + automation around your product), I can propose a practical implementation path and handle the build end‑to‑end.

I help traders take strategies that already make sense and turn them into systems they can run live with confidence. I am an active trader and a systems developer, so I focus on execution quality as much as strategy logic. I build fast execution systems in Python and C++, and I spend most of my time solving the problems that show up in live trading: latency, order routing, broker quirks, webhook failures, exchange edge cases, and the gap between a clean backtest and real execution. My work sits at the intersection of trading automation and applied AI. I build Pine Script strategies and indicators, Python and C++ execution systems, TradingView webhook automation, broker and exchange API integrations, Polymarket automation, and AI-powered research and analysis workflows that help traders make better decisions and operate more efficiently. 🔌 Brokers, exchanges, prediction markets, and market/data systems I have worked with include: Interactive Brokers (IBKR), Tradovate, Bybit, BingX, Binance, KuCoin, Polymarket, Databento, Polygon, Bookmap, Solana RPC, DexScreener, and Jupiter. 🤖 On the AI side, I build workflows using LangGraph, LangChain, RAG pipelines, Neo4j, and LLM APIs. That includes multi-agent research systems, market structure analysis, liquidity analysis, and decision-support tools that help process market information faster and more consistently.

If your agency is spending engineering hours on work that should run automatically, that is a systems problem, not a staffing problem. I build backend automation infrastructure that handles the execution layer your team should not have to think about: data pipelines that self-heal, AI workflows that scale, and integrations that do not break silently on a Friday night. WHAT I BUILD: Data & Scraping Pipelines Production-grade scrapers using Python, Scrapy, Crawlee, and Playwright. Rate-limit handling, proxy rotation, structured output to PostgreSQL, Google Sheets, or your CRM. Built a role-detection system that identified open hiring positions across hundreds of company websites daily and synced results automatically to a client's tracking sheet. n8n & Make Workflow Automation Multi-step workflows connecting CRMs, communication tools, databases, and third-party APIs. Built WhatsApp + Google Sheets + AI pipelines for automated client communication. Email-to-AI-to-database flows with full error handling and Slack alerting on failures. AI-Enriched Pipelines LLM integration via OpenAI, Gemini, and Anthropic APIs inside production workflows. RAG vector pipelines, document parsing (PDF, invoice, form), AI-driven lead enrichment and classification. Token-cost aware: I optimize prompt structures and model selection to keep API costs under control at scale. API Integrations & Custom Backends FastAPI endpoints powering workflow logic, OAuth2 and webhook handling, REST API development. Integrated across Stripe, HubSpot, GoHighLevel, Airtable, Notion, Slack, Google Workspace, and 50+ other platforms. Deployment & Reliability Self-hosted n8n on VPS, GitHub Actions for scheduling, Railway and Google Cloud Run for backend services. Every system ships with error monitoring, exception-handling wrappers, and documentation your team can actually use. TECHNICAL STACK: Orchestration: n8n (Cloud/Self-Hosted), Make, Zapier Languages: Python, Node.js, JavaScript AI: OpenAI API, Google Gemini, Anthropic, RAG Vector Pipelines Data: PostgreSQL, Airtable, Google Sheets Scraping: Scrapy, Playwright, Crawlee, Selenium Backend: FastAPI, REST APIs, Webhooks, OAuth2 Deployment: VPS, Google Cloud Run, Railway, GitHub Actions, Vercel WHO I WORK WITH: I work as an execution partner for agencies and consultants who need reliable backend delivery without the overhead of a full-time hire.
