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)

Blockchain is easy to pitch.
Building something people actually use is where things get interesting.
Over the last 10+ years, I've worked across software engineering, product development, and blockchain infrastructure, helping startups and businesses turn ideas into working products.
A large part of my recent work has focused on:
• Carbon Credit Tokenization
• Real Estate Tokenization
• RWA (Real World Asset) Platforms
• Smart Contracts
• DeFi Applications
• Web3 Products
• Exchange & Trading Infrastructure
I've worked on projects ranging from token ecosystems and blockchain integrations to SaaS platforms, backend systems, automation tools, and customer-facing applications.
One thing I've learned over the years is that most projects don't fail because of technology.
They fail because requirements aren't clear, complexity gets out of control, or important technical decisions are postponed until they become expensive.
That's usually where I get involved.
Sometimes it's a new product.
Sometimes it's an existing platform that needs to scale.
Sometimes it's a project that's been through multiple developers and needs a practical way forward.
What I Can Help With:
Asset Tokenization & RWA
✔ Carbon Credit Platforms
✔ Real Estate Tokenization
✔ Fractional Ownership Models
✔ Asset-Backed Token Solutions
✔ Investor Portals
✔ RWA Infrastructure
Blockchain & Web3
✔ Smart Contract Development
✔ ERC20 / BEP20 Tokens
✔ Wallet Integrations
✔ dApps
✔ DeFi Platforms
✔ NFT Infrastructure
✔ Web3 Integrations
✔ Staking & Reward Systems
Exchange & Trading Systems
✔ Crypto Exchanges
✔ Matching Engine Integrations
✔ Trading Platforms
✔ Wallet Management
✔ Payment Processing
Software Engineering
✔ SaaS Platforms
✔ Backend Systems & APIs
✔ AI Integrations
✔ Automation Solutions
✔ Cloud Infrastructure
✔ System Architecture
✔ Database Design & Optimization
Technology Stack
Blockchain: Solidity, Ethereum, Web3, DeFi, ERC20, BEP20, Tokenization, RWA Infrastructure
Backend: Node.js, TypeScript, PHP, Laravel, Python, REST APIs, GraphQL, Microservices
Frontend: React, Next.js, JavaScript
Infrastructure: AWS, Docker, Linux, CI/CD
Databases: PostgreSQL, MySQL, MongoDB, Redis
Clients Usually Reach Out When
• They need an RWA or tokenization platform built correctly from the start
• A blockchain product needs experienced technical leadership
• Smart contracts require implementation or integration
• Existing systems need blockchain functionality
• Development has slowed down and technical direction is unclear
• An MVP needs to become a production-ready product
• They need someone who can take ownership rather than simply complete tasks
If you're building something in blockchain, tokenization, Web3, or adjacent technologies and need someone who can contribute beyond implementation, I'd be happy to discuss it.

At A Glance: Bitcoin
Bitcoin is the new digital form of money, one that exists solely on the Internet. No one holds it, no one controls it — offering users a new level of privacy in all their online transactions. As a virtual currency, Bitcoin allows users to take the shopping experience to the next level with anonymity, security, and rewards. Many vendors accept this new form of currency, as it offers lower transaction fees than most other kinds of payments. As a business, the ability to accept and utilize Bitcoins can boost your clientele as well as your profits. However, you may not be experienced in this rising craze, or potentially cannot spare the time from your other work to ensure your business, organization, or personal transactions are being managed properly. The Bitcoin specialists on Upwork are here to help, making the Bitcoin experience more efficient, profitable, and easier than ever before.
Fluent in the online workplace, these freelancers boast of excellent communication skills and the ability to collaborate remotely with clarity and efficiency.
