I build blockchain systems and production AI agents. Two lanes, both deep.
Blockchain / Web3
› Solana programs in Rust and Anchor: SPL Token, Token-2022, PDA architecture, CPI patterns
› Solidity across Ethereum, Base, Arbitrum, BSC: tokens, staking, vesting, escrow, marketplaces
› Non-custodial wallet infrastructure: key management, multi-chain RPC, transaction signing
› DEX and AMM integration: Jupiter, Raydium, Meteora (DAMM v2, DLMM), Uniswap V2/V3/V4, PancakeSwap
› Trading systems: market making, order lifecycle and state management, exchange APIs over REST and WebSocket
› Security-first: signer and owner checks, reentrancy guards, overflow-safe math, audit-ready by default
AI Agents & Automation
› Claude API and Claude Code as daily drivers: tool use, structured outputs, subagents, prompt caching
› MCP servers exposing real systems (CRMs, ad platforms, internal APIs) as agent-callable tools
› RAG pipelines with pgvector: metadata filtering, reranking, source-citation verification
› Human-in-the-loop approval gates for anything that moves money or sends on your behalf
› n8n self-hosted on Docker, plus Make and custom Python and Node workers
› Eval harnesses so a prompt change doesn't silently degrade quality
Stack: TypeScript, Rust, Python, Node.js, NestJS, FastAPI, Next.js, React, React Native, PostgreSQL, pgvector, Redis, Docker, AWS, Vercel
Selected work
- Klip AI: live non-custodial multi-chain wallet on iOS, Android and web (Solana, Ethereum, Base, Arbitrum) with an embedded AI agent
- Pump.fun-style launch platform: bonding curve pricing, graduation flow, automatic LP seeding
- Meta Ads MCP server plus an autonomous ad-monitoring agent with Slack approval
- CTO on a Telegram trading bot build ($16k engagement, delivered)
Based in Lahore, Pakistan (GMT+5). I overlap comfortably with EU and US hours.
Some client work is under NDA. Happy to walk through it on a call.

I help startups and growing businesses build fast, scalable SaaS platforms, AI-powered applications, custom ERP systems, and web and mobile apps using Python, Laravel, React Native, Next and React. I work as a full stack developer who can take a product from idea to production with clean code and predictable delivery. If you need a reliable web developer for modern UI work and a strong mobile app developer for iOS/Android builds, I can cover both while staying hands-on as a full stack developer focused on performance, UX, and maintainability. I’ve delivered solutions for founders who need speed now and stability later, and I communicate clearly at every step.🔥
I’m an experienced Web engineer, React and Next.js engineer, Vue engineer, and React Native engineer with 7 years of production experience. As a full stack developer I can build backend APIs, admin panels, dashboards, and customer-facing apps, and as a web developer I pay attention to UI details that improve conversion and retention. I’ve completed a wide range of successful projects, from MVPs to large systems with long-term maintenance and continuous improvements.
🚀I also lead a web development team, techXen Solutions . We have multiple Laravel developers (Senior PHP and Custom PHP MySQL), Python (Django), and JavaScript (React, Vue, React Native) developers. If your project needs a dedicated mobile app developer, we can staff that role quickly, while I stay involved as a full stack developer to keep architecture, delivery, and communication aligned. When the UI scope grows, a senior web developer can join the project while I remain the full stack developer responsible for end-to-end quality.🚀
Our team has already worked in such industries as:
✅ Inventory & Warehouse Management
✅ Marketplace
✅ E-commerce
✅ Travel and Hospitality
✅ Custom ERP (Enterprise Resource Planning)
✅ AI & Automation (AI Agents, AI Calling Agents, Voice AI, LLMs, Chat)
✅ Automotive (car inspection, automotive ERP, car sharing, rental, selling)
✅ Social media (Tinder-like networks, short video platforms, communities)
✅ Sales (CRM systems for sales teams, retail, hospitals, sales departments)
✅ Sport (gym management systems, trainer platforms, fitness apps, club portals)
✅ Legal (document automation, AI-assisted legal processing)
✅ Healthcare (clinic management, booking, mental health software)
✅ Education (LMS, automated training, coaching marketplaces)
✅ Finance (fintech platforms, investment platforms, bank API integrations, calculators)
✅ Manufacturing (shop floor management and automation)
✅ Human resources (HRM systems)
✅ Digital marketing (Meta, Facebook/Instagram, TikTok, Google APIs, analytics)
Stack of technologies we use:
✅ HTML/CSS, Bootstrap, Tailwind
✅ JavaScript (React, Next.js, Vue, Node.js, Express, AdonisJS, Nuxt)
✅ React Native for cross-platform mobile delivery
✅ API integrations (Stripe, PayPal, Twilio, TextMagic, Xero, DocuSign, Google Maps, Meta APIs, and more)
✅ API development (Laravel, Node/Express, Firebase, Python/Django, Go, REST, GraphQL)
✅ PWA (Progressive Web App)
✅ Databases: MySQL, PostgreSQL, MongoDB, DynamoDB, Elasticsearch
✅ Infrastructure: AWS, DigitalOcean, Firebase, Supabase
✅ DevOps and administration: LAMP, CentOS, Ubuntu
As a full stack developer, I connect the front end, back end, and infrastructure so releases are smooth. When the scope includes native-like UX, I can collaborate with a mobile app developer without slowing down the API roadmap, and a web developer can refine UI flows while we keep the backend stable.
You can hire me as a full stack developer for full ownership, or extend the team and keep me as the full stack developer leading architecture and delivery. If timelines are tight, add a mobile app developer to parallelize mobile features, and add a web developer to accelerate dashboards and front-end work.
🚀 Buzz words clients search for: website development, JavaScript, React MySQL, Amazon Web Services, API integration, AI Agents, CRM, custom ERP, REST, GraphQL, Laravel, React, Next js, Vue, React Native. If you need a full stack developer who can also guide a delivery team, I’ve done that for years. If you need a reliable mobile app developer for consistent releases and store readiness, we can support that too, and if you need a web developer for pixel-perfect UI, that’s covered.
In our work history you’ll find successful products built with React, JavaScript, MySQL, React, Vue, and React Native, plus multiple systems built with Python (Django, Flask, FastAPI). I also use LLM capabilities and AI APIs (including OpenAI integrations) when they genuinely improve the product experience.
We have 15 senior developers across React, JavaScript, MySQL, Python, Go, and Node.js. As a full stack developer, I can jump into an existing codebase, stabilize releases, fix bottlenecks, and plan the next iterations.
Please contact me for further details and fruitful work.

Have you ever launched a blockchain or AI project that looked great on paper but fell apart in production? I've spent 8 years making sure that doesn't happen, across token launches, DeFi protocols, NFT platforms, and now AI agents and LLM-powered systems.
𝗛𝗲𝗿𝗲'𝘀 𝘄𝗵𝗮𝘁 𝘁𝗵𝗮𝘁 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 𝗹𝗼𝗼𝗸𝘀 𝗹𝗶𝗸𝗲 𝗶𝗻 𝗽𝗿𝗮𝗰𝘁𝗶𝗰𝗲:
Delivered an ERC20 token that reached an $18M market cap. Helped a blockchain startup close $10M in funding with audit-ready smart contracts. Built a multi-chain NFT marketplace that generated $1M+ in sales. More recently, built AI agents and LLM integrations that automate trading logic, customer workflows, and on-chain data analysis.
These aren't team numbers. These are projects I was directly responsible for.
𝗪𝗵𝗮𝘁 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 𝘀𝗮𝘆 𝗮𝗳𝘁𝗲𝗿 𝘄𝗼𝗿𝗸𝗶𝗻𝗴 𝘄𝗶𝘁𝗵 𝗺𝗲:
"Delivered ahead of schedule and the contract logic was airtight, exactly what we needed before our raise."
"Came back for a second project. That says everything."
"Flagged a vulnerability our previous dev missed. Saved us from a serious exploit."
𝗪𝗵𝗼 𝗜 𝘄𝗼𝗿𝗸 𝘄𝗶𝘁𝗵:
I work with founders, CTOs, and product teams building serious blockchain infrastructure or AI-powered products, not weekend side projects. If your project involves real capital, real users, or a real audit, that's where I'm most useful.
𝗔𝗜 & 𝗟𝗟𝗠 𝘀𝘆𝘀𝘁𝗲𝗺𝘀: AI agents, LangChain workflows, OpenAI/Claude API integrations, automated trading and analytics agents, chatbot and support automation
𝗗𝗲𝗙𝗶 𝗽𝗿𝗼𝘁𝗼𝗰𝗼𝗹𝘀: DEX platforms, staking systems, yield farming, token launchpads, cross-chain bridges. 𝗧𝗼𝗸𝗲𝗻 𝗲𝗰𝗼𝘀𝘆𝘀𝘁𝗲𝗺𝘀: ERC20, BEP20, SPL tokens with custom tokenomics, vesting, and IDO/ICO structures
𝗡𝗙𝗧 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺𝘀: marketplaces, GameFi, dynamic NFTs, royalty systems, IPFS hosting
𝗦𝗺𝗮𝗿𝘁 𝗰𝗼𝗻𝘁𝗿𝗮𝗰𝘁 𝘀𝗲𝗰𝘂𝗿𝗶𝘁𝘆: audit support, vulnerability assessment, gas optimization, test coverage with Hardhat and Foundry
𝗖𝗿𝘆𝗽𝘁𝗼 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻: MEV bots, arbitrage systems, Telegram trading bots, copy trading infrastructure, now paired with AI decision layers
𝗙𝘂𝗹𝗹 𝘀𝘁𝗮𝗰𝗸 𝗱𝗔𝗽𝗽/𝗔𝗜 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁: from Solidity or Rust contracts to Python AI backends to React/Next.js frontend

𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸:
I don't disappear after handing over code. Most of my clients come back for the next project and the one after that. I give daily or weekly updates depending on the project's scope, flag problems before they become blockers, and write contracts and systems that your auditor won't send back with a list of critical findings.
𝗖𝗼𝗺𝗺𝘂𝗻𝗶𝗰𝗮𝘁𝗶𝗼𝗻: Slack, Telegram, JIRA, Trello, GitHub, whatever your team already uses.
8 years. 3 major outcomes. 0 exploited contracts.

Most developers will build what you ask for.
I help you build what actually works.
I’m a mobile app developer with 10+ years in IT and a small team behind me. We help startups go from idea → MVP → scalable product - not just code.
At the same time, I’m building my own SaaS product, so I understand the full journey:
validation, MVP, users, retention, monetization.
🚀 How I can help you
- Turn your idea into a clear MVP plan
- Build fast using FlutterFlow + Flutter
- Avoid overbuilding and wasted budget
- Design product logic, not just screens
- Prepare your app for real users & growth
👉 Already have everything defined?
We can jump straight into development and deliver efficiently.
🎨 Design support
- UX/UI design from scratch
- Improving existing designs
- Product-focused user flows (not just visuals)
📱 What I do
- MVP development (fast & lean)
- FlutterFlow development
- Flutter app development
- Full-cycle product development
- Firebase / Supabase backend
- Subscriptions (RevenueCat, Stripe)
⚡ Why clients choose me
Because I don’t think like a freelancer.
I think like a product partner:
- I challenge weak ideas
- I simplify scope to launch faster
- I focus on what brings real value
⚠️ Not a good fit if:
- You’re looking for the cheapest option only
- You want someone to blindly follow tasks
✅ Perfect fit if:
- You’re building a startup or MVP
- You want to move fast and build it right
- You need someone to think with you, not just code
💬 Send me your idea, Figma, or even a rough concept -
I’ll break it down and suggest the best way to build your MVP.
