Hire the Best Systems Developers in Lahore, PK

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.

Turning MVPs into Scalable, Revenue-Generating Product I build production-grade AI systems that plug directly into real businesses, cutting operational costs, eliminating manual workflows, and turning LLM reasoning into measurable revenue. Not demos. Not experiments. Infrastructure that works. 𝐖𝐢𝐭𝐡 𝟕+ 𝐲𝐞𝐚𝐫𝐬 𝐢𝐧 𝐛𝐚𝐜𝐤𝐞𝐧𝐝 𝐚𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮r𝐞 𝐚𝐧𝐝 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧 𝐀𝐈, I've delivered enterprise-grade Generative AI systems for enterprise companies and SaaS founders that run reliably under real-world load at scale, on budget, and with predictable results. Real Results. Real Numbers. 🔸 70–90% reduction in manual operations 🔸 2X increase in qualified appointments via AI-driven workflows 🔸 60% campaign cost reduction through intelligent automation 🔸 95%+ accuracy in enterprise database intelligence agents 🔸 99% cost reduction on market intelligence pipelines 🔸 29% conversion rate improvement via hybrid RAG retrieval These aren't estimates. These are outcomes from systems I've built and deployed. 🔧 Core Services ① AI Agents & CRM Automation I build autonomous backend AI agents that take real actions, not hardcoded bots that break under edge cases. My agents update and sync HubSpot, Salesforce, Pipedrive, and GoHighLevel, qualify inbound leads, trigger follow-ups, schedule appointments, and execute multi-step decision workflows with tool access, live API calls, and persistent memory all connected through Zapier and native integrations across your full sales and ops stack. ② LLM & RAG Engineering Production LLM systems built across OpenAI (GPT-4o, GPT-4.x), Claude (Anthropic), and Grok with intelligent model routing, fallback logic, and cost controls built in from day one. I design structured RAG pipelines using pgvector, ChromaDB, and Pinecone with hallucination reduction, guardrails, token optimization, cost tracking, and runtime-controlled AI behavior. Multi-agent architectures handling 10+ coordinated agents. Systems engineered to behave predictably under real business constraints, not just in testing. ③ Voice AI Systems Real-time voice pipelines built on VAPI and ElevenLabs (TTS), with Whisper streaming STT, WebSocket architecture, interruption handling, and session memory delivering sub-second latency across phone, web, and WhatsApp channels. I deploy voice AI that holds natural, production-grade conversations, not scripted demo flows that fall apart when a user goes off-script. ④ Backend & SaaS Architecture AI-first backend systems using FastAPI, PostgreSQL, MongoDB, Redis, SQLAlchemy, Docker, AWS, and GCP with async services, background workers, event-driven workflows, multi-tenant SaaS patterns, and full CI/CD pipelines. AI is infrastructure here not a frontend feature bolted on after the fact. ⑤ Deep Platform Integrations Twilio, WhatsApp Business API, Meta APIs, Stripe, Mailgun, OAuth flows, webhooks, and retry logic multi-platform automation pipelines built to operate reliably at enterprise scale without babysitting. 🏆 Flagship Work BookleeAI Multi-Channel AI Booking & CRM Automation Platform A full-stack AI platform combining voice, chat, and WhatsApp into one unified assistant — with a RAG-powered business knowledge engine, automated booking and follow-up workflows, real-time communication orchestration, and admin analytics dashboards. Enterprise Deployments: 🔸 Market intelligence automation system — 99% cost reduction 🔸 Natural language database querying engine across 1,000+ tables 🔸 CRM-integrated AI lead qualification pipeline deployed at scale 🔸 Hybrid RAG retrieval system 29% conversion rate improvement 💡 What Makes Me Different Most freelancers build chatbot demos, hardcode prompts, and ignore scalability. I build AI infrastructure architected for scale from day one, optimized for latency, cost, and reliability, and delivered as complete production-ready systems. You get end-to-end ownership: architecture, backend, AI pipelines, deployment, and ongoing optimization, not a hand-off after a prototype. ✅ I Work Best With SaaS founders adding AI-powered features → CTOs scaling backend AI infrastructure → Agencies delivering automation services → Businesses replacing manual sales workflows with AI Not the right fit for: one-off scripts, simple chat widgets, or pure frontend tasks. 🟢 If you need Generative AI, LLM engineering, RAG systems, Voice AI, or CRM automation built for production, not experimentation, let's talk. Send a message, and I'll walk you through the right architecture for your system.

Businesses often outgrow spreadsheets, disconnected tools and off-the-shelf software that no longer fits how they operate. I design and build custom, database-driven business systems that bring processes, users and information together in one reliable platform. I work as a long-term technical partner for organizations that need complete, end-to-end solutions, including: • Custom CRM and ERP systems • Customer, member, employee and vendor portals • SaaS and multi-tenant web platforms • Internal operations and workflow systems • Database design and administration tools • Reporting dashboards and management visibility • API integrations and data synchronization • Legacy-system modernization and data migration As a Top Rated Plus Upwork professional with $300K+ earned and 6,900+ hours, I combine full-stack development, systems analysis and technical project leadership. I can take a project from initial discovery and process mapping through architecture, database design, development, testing, deployment and ongoing improvement. My experience includes building and supporting membership systems, admissions and learning platforms, expense-management workflows, operational dashboards, administrative portals, marketplace platforms and API-connected business applications. My approach is practical and structured: 1. Understand the business process and existing pain points 2. Define users, roles, workflows, data and reporting requirements 3. Design a maintainable system and database architecture 4. Deliver the solution incrementally with regular demonstrations 5. Manage testing, deployment, documentation and user adoption 6. Continue supporting and improving the platform as the business grows Core technologies include C#/.NET, ASP.NET, PHP, JavaScript, SQL Server, MySQL, REST APIs, HTML/CSS, Power Platform and modern web-development frameworks. Automation and AI can be incorporated where they deliver genuine business value, but the foundation is always a secure, maintainable and usable business system. I am best suited to clients looking for more than a short coding assignment—especially organizations seeking a dependable technical partner who can understand their operations, own delivery and support the system over the long term. Let's discuss your project and get the ball rolling, Zain H.

I build production-ready Generative AI application,AI Agents, RAG chatbots, LangGraph multi-agent systems, and n8n workflow automation not demos that break when real users arrive. If your business is still running on manual follow-ups, half-finished AI prototypes, or disconnected workflows, that's not a technology problem. It's a systems problem.
