Though I can work in many different domains my favorites are artificial intelligence, web development and algorithm development. I'm keen on working on game development too.

96.8% retrieval accuracy. 150-page contracts processed in under 60 seconds. Zero cross-tenant data leakage. I build RAG and AI systems that survive real production, not just demos, and clients keep hiring me back to build the next one. I'm Top Rated Plus, with 3+ years building AI systems and 7+ years in full-stack engineering. A lot of my work is repeat business. One client has brought me back 5+ times, because the systems hold up after launch, when real users and messy data arrive. RAG and document intelligence are my deep end, but I build complete production systems end to end: SaaS platforms, automations, and full-stack MVPs. The same discipline that keeps a RAG system reliable keeps the simpler builds clean, which is why teams trust me with both. RECENT WORK DocsFlow | Document Intelligence Platform 96.8% retrieval accuracy Hybrid search with source-linked, citation-backed answers 150-page documents processed in under 60 seconds, down from 3 to 5 minutes Four-layer tenant isolation with zero cross-tenant data leakage Around 85% AI cost reduction through model routing and caching SureCiteAI / LPA Analyzer | Legal & Contract Intelligence RAG across thousands of documents with grounded, citation-validated outputs Deterministic validation layer so financial figures are never generated by the LLM Built for legal and compliance-sensitive workflows LeadFlow AI | Multi-Agent Operations Platform AI-powered qualification, routing, and follow-up Integrated across Supabase, WhatsApp, APIs, and n8n Reduced manual operational effort by 40 to 70% (Also: multi-agent game-dev systems and real-time computer vision for fitness. Happy to share.) WHY TEAMS HIRE ME A cheaper freelancer can usually get an MVP working. The problems show up later, when real users, messy data, scaling, edge cases, security, and AI cost all arrive at once. That is exactly when architecture starts to matter, and when getting it wrong gets expensive. I'm more senior and product-minded than a typical freelancer, but more hands-on and cost-effective than an agency or an early senior hire. In practice: fewer wrong turns, faster decisions, and a system built right from day one.

SPEAKING TechStars Startup Week, DeFi Summit London, LevelUP KL Tell me what you're building and the outcome you need. If it has to actually work in production, that's where I'm strongest.

I am a backend software developer with over 5 years experience in systems programming. I like to develop scalable applications and take on challenging tasks. My focus is on distributed systems, compilers and databases.

I’m a senior full-stack engineer (6+ years) who builds scalable, production-ready web and blockchain apps using React, Next.js, Node.js, , TypeScript, Golang, Solidity, Rust, PHP e.t.c. I specialize in merging clean architecture with real-world speed — shipping complete products that don’t break under pressure. My background spans FinTech, Healthcare, Real Estate, and AI automation, where I’ve delivered end-to-end SaaS dashboards, CRMs, CMSs, and blockchain dApps. I move fast, write maintainable code, and integrate complex systems seamlessly. ✅ Core Technical Stack Frontend: React.js, Next.js, TypeScript, TailwindCSS Backend: Node.js, Nest.js, Express, PostgreSQL, MongoDB Blockchain: Solidity, Web3.js, Ethers.js, Solana, Smart Contracts, Wallet Integrations Automation / AI: n8n, Make.com, Zapier, LangChain, OpenAI APIs DevOps: Docker, CI/CD, AWS, Vercel, GitHub Actions Integrations: OAuth, Twilio, Payment Gateways, Google/Meta APIs I’m not just a coder — I help teams architect, automate, and deploy real systems that scale. Whether it’s integrating AI workflows, building blockchain-powered products, or setting up robust CI/CD pipelines, I deliver clean results and clear communication. If you need a developer who can own projects from prototype to production, move quickly, and think like an engineer — let’s build something that lasts.

Your team didn't sign up to copy-paste data, chase follow-ups, or babysit workflows that should run on autopilot. I build AI automation systems that close that gap. Not prototypes. Not "works in demo" scripts that fall apart the moment a real edge case hits. Systems that run quietly in the background, handle the repetitive work your team hates, and give back the hours your business is quietly hemorrhaging every week. I've worked with fintech companies, SaaS founders, and ops-heavy businesses across the US, UK, and Southeast Asia. The patterns are almost always the same, a growing team, a manual ops layer underneath it, and a founder who knows it needs to change but hasn't found someone who can own the architecture and the build at the same time. That's the gap I fill. The tools I work with most are n8n, Make. com, LangChain, LangGraph, OpenAI API, Python, Node.js, and Pinecone, but I pick based on your problem, not my preferences. Before anything gets built, you get a full architecture blueprint. You see exactly what's being built and why before a single line of code is written. Every delivery includes documentation and a Loom walkthrough so your team owns the system after handoff, no dependency on me to keep the lights on. If your job post has the words "automate our operations," "we're still doing this manually," or "our team is drowning in repetitive work", message me. Tell me what you're trying to fix. We'll take it from there.

Full-Stack Developer | Java Spring Boot • TypeScript • React With 8 years of professional development experience, I build robust, scalable applications that solve real business problems. I specialize in modern full-stack development, delivering clean code and reliable solutions. Technical Expertise: • Backend: Java, Spring Boot, RESTful APIs, microservices architecture • Frontend: React, TypeScript, responsive UI development • Database: SQL/NoSQL design and optimization • DevOps: CI/CD pipelines, cloud deployment, containerization What I Deliver: Clean, maintainable code that follows best practices and industry standards. Whether you need a complete application built from scratch, legacy system modernization, or specific feature development, I bring technical excellence and problem-solving skills to every project. My Approach: I focus on understanding your business requirements first, then translating them into efficient technical solutions. Clear communication, thorough testing, and meeting deadlines are non-negotiable in my workflow. Available for both short-term projects and long-term collaborations. Let's discuss how I can contribute to your project's success.

Most backend systems work fine until real users arrive , then APIs slow down, automation breaks under load, and AI integrations that worked in testing fail in production. That's the gap I close. I build backend systems, AI automation pipelines, and cloud infrastructure designed for real-world conditions from day one not patched together after the first failure. Where I typically get involved: AI automation systems replacing manual workflows — n8n, Make com, LangChain, and agent-based pipelines built for production scale Backend architecture using Node.js and Python — API design, scalable systems, and microservices that handle real traffic AI integration into existing products — OpenAI, LLM workflows, AI agents connected cleanly to backend systems DevOps and cloud infrastructure — AWS, Terraform, Docker, CI/CD pipelines built for reliability Data pipelines and web scraping — extraction, processing, and automation at scale using Python and Node.js Full stack delivery when needed — MEAN/MERN stack with clean frontend-backend architecture How I work: Architecture first, no quick fixes. Every system I build is designed to scale, stay maintainable, and not create technical debt that costs more to fix than it would have to build correctly. I've maintained long-term client relationships because the first version doesn't need to be rebuilt six months later. Tech Stack: Node.js | Python | Django | MEAN Stack | MERN Stack n8n | Make com | LangChain | AI Agents | OpenAI API AWS | Terraform | Docker | CI/CD | DevOps PostgreSQL | MySQL | MongoDB | REST APIs | API Integration Data Scraping | Web Crawling | Scalable Data Pipelines LLM Prompt Engineering | AI Implementation | Automated Workflows If you're building something backend or AI-driven and need it to work reliably at scale, let's talk.

Some developers need a full specification before they start thinking. I start solving the moment you start talking. Whether you are building a new AI-powered SaaS MVP from scratch, or you already have one that is not performing the way it should, I come in as a full stack technical partner, understand the business, and build systems that are production-ready from day one. Not prototypes that need rebuilding in six months. Not demos that break under real load. Actual systems built to scale, using Next.js, Supabase, and modern production-grade infrastructure. I work on projects starting from $3,000. If that does not align with your budget, I would rather be upfront now, there are plenty of developers at every price point, and finding the right fit matters more than just filling a slot.
