Hire the Best Bitcoin Developers
in Pakistan

I build production grade systems at the intersection of Web3, fintech, and AI from high frequency trading infrastructure to DeFi protocols and ML powered signal engines. Recent work includes a perpetual DEX built from scratch comparable to Hyperliquid, a high frequency trading bot on Polymarket's BTC prediction market using real time CLOB streams and millisecond latency execution, and ML models trained to find correlations across thousands of markets to generate trading signals seconds before a market moves. I've also built and scaled a crypto exchange handling 20 million transactions daily with zero security incidents over six years. On the AI development side, I build and deploy LLM powered applications using OpenAI, Anthropic, and open-source models (LLaMA, Mistral). This includes RAG pipelines with vector databases (Pinecone, Weaviate, pgvector), AI agents and tool use workflows with LangChain and LlamaIndex, fine tuning models for domain specific tasks, and integrating AI layers into trading systems for signal filtering and adaptive strategy logic. On the fintech and payments side, I've worked directly with Transak, MoonPay, and Paybis including a year long direct collaboration with the Paybis team across two projects integrating card, Apple Pay, and Google Pay flows into Binance scale platforms. I've built full KYC pipelines via Sumsub, crypto wallet infrastructure with multisig key management, and mobile apps for iOS and Android in the crypto and payments space. Infrastructure wise, I design for scale from the start — Kubernetes, EKS, microservices, clustered databases, Kafka, and the full AWS stack. Security is treated as a core requirement, not an afterthought, across every fintech and blockchain system I've shipped. Core areas: Web3 / DeFi / Solana / EVM · HFT & algorithmic trading · ML/AI for trading signals · LLM integrations · RAG & AI agents · Crypto exchange development · Fiat onramp integrations · Cloud infrastructure (AWS, GCP) · Mobile (React Native, iOS, Android) · Smart contracts (Solidity, Hardhat, Foundry)

I help startups, SaaS companies, and e-commerce brands turn data and AI into real business results — smarter predictions, faster automation, and high-impact AI content. With 100% Job Success across 26 projects on Upwork, I deliver production-ready solutions across five high-growth AI and data disciplines: MACHINE LEARNING ENGINEERING I design, train, and deploy predictive models for churn prediction, demand forecasting, lead scoring, recommendation engines, and anomaly detection. Stack: Python, Scikit-learn, XGBoost, PyTorch, TensorFlow, MLflow. DATA SCIENCE & ANALYTICS End-to-end data pipelines, exploratory analysis, experiment design (A/B testing), KPI dashboards, and clear reports that non-technical teams can act on. Tools: Python, Pandas, NumPy, SQL, Matplotlib, Seaborn. AI & PROMPT ENGINEERING I build LLM-powered workflows, RAG chatbots, and multi-agent systems using GPT-4/4o, Claude, LLaMA, LangChain, Hugging Face, and vector databases (Pinecone, ChromaDB, Neo4j). Prompt libraries, FAQ bots, research copilots, and AI-driven content automation integrated with your existing tools (Slack, Notion, Shopify, CRM). AI VIDEO SPECIALIST I produce AI-generated video content — product explainers, training modules, and social media clips — using AI avatars, voice synthesis, and prompt-driven scripts. AI video grew 329% year over year on Upwork in 2025 and I stay current with the latest tools to deliver fast, scalable content packages. CYBERSECURITY-AWARE AI SYSTEMS I build AI and ML solutions with security best practices baked in — controlled data access, secure API usage, and audit-friendly pipelines aligned to your organization's policies. TYPICAL DELIVERABLES - ML models: forecasting, classification, regression, anomaly detection - NLP pipelines: sentiment analysis, topic modeling, document Q&A - LLM apps: RAG chatbots, AI agents, prompt libraries, workflow automation - AI video: short-form clips, product demos, training videos - Dashboards and reports stakeholders can use without a data background Why clients work with me again: 100% Job Success | Clear communication | Business-first thinking | Fast turnaround Share your goal and I will propose a concrete plan with timeline, deliverables, and milestones.

A Full Stack AI Developer who builds production-ready, AI-powered web applications that hold up under real-world use. My work sits at the intersection of Full Stack Developer and AI Developer, pairing modern LLM features with clean React frontends and reliable Node.js & Python backends, so you get one engineer who can own a product end-to-end instead of splitting it across a separate React developer, backend developer, and AI specialist. As an AI Developer, I help founders and teams add intelligence to their products that actually works in production not throwaway demos. I build LLM-powered features, RAG chatbots, AI Automations using tools like N8N, Zapier, Make and Claude and AI agents using the OpenAI and Claude APIs, LangChain, and Custom GPT integrations, with a focus on systems that are reliable, observable, and cost-controlled. Recently I designed and shipped AI automation and Custom GPT workflows that streamlined real business operations, and I supervised the launch of a B2B SaaS AI platform through architecture and code review work my clients rated 5 stars. As a Full Stack Developer, I take ownership of the whole system. My frontend work is React and Next.js with TypeScript and Tailwind CSS; my backend work is Node.js, Express, NestJS and Python, exposing clean REST and GraphQL APIs. This end-to-end ownership is why clients bring me in as a Full Stack AI Developer rather than coordinating three roles. I keep the architecture coherent from database to UI, and I make sure AI features integrate cleanly into the product instead of sitting bolted on the side. A large part of my work involves turning an idea or a rough prototype into a stable, scalable platform: multi-role dashboards, admin panels, subscription and authentication systems, and the API layer that ties LLM and AI agent features into the product. I've built SaaS platforms serving thousands of users and shipped crypto wallets that handle real transactions, so I'm comfortable with the parts of a product where data integrity, security, and performance genuinely matter.

𝐇𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤: I think like a product owner, not just a coder. Before writing code, I align on the business outcome who the user is, what they pay for, and where the product needs to be in six months. Then I ship in clear weekly milestones, communicate proactively, and stay available for fast turnaround. The result is a 100% Job Success score and clients who come back for their next build.
