If you need an indicator, hire anyone. If you need a system that survives production, keep reading. Most trading devs have built an EA. I've built prop firms, and I still run them. I'm an Algorithmic trading systems developer, having experience with MetaTrader (MT5/MT4, MQL5/MQL4), Python, and quantitative infrastructure, Expert Advisors, trading bots, prop firm platforms, backtesting engines, and AI signal generation for forex, crypto, and equities. I build these systems end to end: strategy logic, execution layer, risk engine, and the infrastructure that keeps it running when real money is on the line. Where I've done it: Prop firms (3+ built, currently managing live), challenge and evaluation engines, drawdown and rule enforcement, trader dashboards, payout logic, MT5 integration. AI-driven signal generation systems. Custom indicator platforms. Real-time alerting infrastructure. Autonomous systems that run without me watching them. The stack: • MQL5 / MQL4 - Expert Advisors, custom indicators, execution logic, backtest optimization • Python - strategy research, backtesting, broker & exchange APIs, live execution engines • AI/ML - signal generation, model integration, decision layers • The layer around it - FastAPI/Django APIs, dashboards, Telegram/Discord alerts, deployment What actually separates me: Production experience. I've watched traders find the gap in a rule engine I wrote. I've dealt with latency, slippage, broker quirks, edge cases in breach logic, the things that never appear in a backtest and always appear in week two. That's the difference between code that works and a system that holds. Tell me what you're building. I'll tell you straight whether it's feasible, where the scope will bite you, and what it'll actually take, before you spend anything.

I work with service businesses, agencies, and operations teams whose leads, conversations, quotations, appointments, invoices, tasks, and customer records are scattered across disconnected platforms. I design CRM and workflow automation that brings these processes together, removes repetitive administration, prevents data errors, and gives teams a reliable system for managing customers and daily operations. 🏆 Top Rated Plus ✅ 100% Job Success Score ⭐ 4.9 rating across 86 ratings 💼 144 completed Upwork jobs ⏱ 3,700+ Upwork hours 🧠 13 years of technical experience My core platforms include GoHighLevel, HubSpot, n8n, Zapier, Make (Integromat), ActiveCampaign, Zoho CRM, ClickUp, Monday CRM, REST APIs, webhooks, OpenAI, and custom Node.js integrations. Documented results from recent projects include: • Reduced automation costs by more than 90% by replacing expensive Zapier workflows with a custom HubSpot–JobTread integration. • Maintained zero duplicate records while synchronizing jobs, deals, contacts, vendors, tickets, daily logs, and documents. • Reduced administrative workload by over 80% by connecting ActiveCampaign, Zoho CRM, Zoho Books, Zoho Desk, OnceHub, and Zapier. • Achieved complete synchronization across CRM, invoicing, payments, scheduling, support, and reporting. • Delivered bidirectional HubSpot–ClickUp synchronization with zero reported update loops. • Built AI-powered GoHighLevel workflows that summarize conversations across thousands of CRM contacts. • Connected approximately 10 operational stages across quotations, orders, purchasing, production, inventory, dispatch, and accounting. • Integrated QuickBooks, Xero, Sage, Pastel Partner, and Evolution into one operational order-management platform. I can help you implement: • GoHighLevel pipelines, opportunities, tags, custom fields, forms, workflows, email, and SMS automation • HubSpot deals, contacts, companies, properties, dashboards, pipelines, and workflow automation • n8n, Zapier, and Make workflow development, optimization, repair, and migration • Lead capture, qualification, assignment, nurturing, and follow-up workflows • Quotation, contract, appointment, onboarding, invoicing, and payment automation • CRM migration, data cleaning, field mapping, and pipeline recreation • Bidirectional synchronization between CRM, project-management, accounting, scheduling, and support platforms • REST API, webhook, and third-party application integrations • AI conversation summarization and structured CRM-note generation • Duplicate prevention, trigger-loop prevention, retries, logging, reconciliation, and error handling • Custom Node.js middleware where native integrations cannot support the required business process • Zapier and Make cost audits, including migration to self-hosted n8n or custom integration infrastructure My process begins with mapping the complete workflow: where information enters, which teams use it, how records move between systems, what conditions trigger the next action, and where failures currently occur. From there, I design the CRM structure, integrations, automation logic, validation rules, failure handling, and reporting required to keep the process dependable after deployment. Send me your current workflow, CRM setup, or automation problem. I’ll review the process, identify the gaps, and recommend the right implementation approach.

An AI demo can look great until real users start using it. Then things like wrong answers, slow responses, high costs, data issues, and scaling problems start to matter. Some systems I have worked on handle 1M+ monthly requests. A good AI system needs more than an LLM. It needs the right data, RAG, AI agents, APIs, databases, integrations, security, and a backend that can handle real traffic.
