Services
I work across crypto and AI: the contracts, the bots, the data tools and the backends behind them. Pick what you need, or tell me the problem and I'll tell you which of these it is.
Solidity contracts designed, tested and deployed for production: tokens, launchpads, multi-DEX swap routers and upgradeable architectures (diamond / EIP-2535 and transparent proxies).
Who it's for
Token teams and DeFi startups who need contracts that can ship, be verified and be upgraded safely.
What's included
- Contract architecture and upgrade strategy
- Solidity implementation with Hardhat + TypeScript tests
- Deployment and explorer verification scripts
- Handover docs for your team

Telegram bots that do real on-chain work: deploy and verify tokens, guard groups against spam and bots, push gas and price alerts, and sell paid packages with crypto payments.
Who it's for
Crypto communities and projects that run on Telegram and want automation their members actually use.
What's included
- Bot commands and conversation flows
- Wallet, token and explorer API integrations
- Crypto payment flow for paid features
- Admin and broadcast tools, hosting setup

Tools that turn raw chain data into answers: top holders and their history, wallet behaviour, airdrop recipients, historical snapshots and clean CSV exports.
Who it's for
Founders, analysts and communities who need to understand who holds a token and what wallets are doing.
What's included
- Data extraction from explorers, APIs or nodes
- Filters, snapshots and structured exports
- Dashboards (React / Node.js) when you need a UI
- Documentation so you can rerun it yourself
The backend behind a Web3 product: APIs, wallet flows, transaction handling, crypto payment gateways and batch automation across many wallets.
Who it's for
Products that need reliable chain integrations behind their app or website.
What's included
- API design and data models
- Wallet, signing and transaction pipelines
- Crypto payment gateway integration
- Validation, logging and safety checks
Backend architecture for AI products in demanding environments: Python (FastAPI) microservices, Kafka/Redis event pipelines, LLM integration and cloud deployments.
Who it's for
Teams building AI products that need to be secure, observable and ready for regulated customers.
What's included
- Service architecture and API design
- Event-driven pipelines (Kafka, Redis)
- LLM and AI API integration
- Cloud deployment (GCP) and hardening

A hands-on review of your Solidity code for common vulnerability classes, access-control mistakes and upgrade risks, with a written list of findings and fixes.
Who it's for
Teams about to launch, or preparing for a formal audit, who want a second set of experienced eyes first.
What's included
- Manual review of the contracts in scope
- Findings ranked by severity, with fix suggestions
- Upgradeability and access-control check
- Follow-up review of your fixes
How a project runs
Free 20-min call
You explain the goal; I ask the questions that decide scope and risk.
Scope & quote
A written scope with milestones and a fixed quote or milestone plan.
Build in the open
Regular check-ins, a repo you can see, tests with the code.
Handover
Deployment, documentation and a walkthrough for your team.
Questions clients ask
Short answers first. If yours isn't here, ask it on a call.
What kind of projects do you take on?
Smart contracts and DeFi systems, Telegram crypto bots, on-chain analytics tools, Web3 backends and AI platform backends, plus focused security reviews of Solidity code. If your project sits between crypto and AI, that is exactly where I work.
Which chains and stacks do you work with?
EVM chains (Ethereum, BNB Chain, Polygon) with Solidity, Hardhat, ethers.js, web3.js and web3.py, and the XRP Ledger in Python. On the backend: Node.js / Express, Python / FastAPI, PostgreSQL, MongoDB, Kafka, Redis and GCP.
Can you review my smart contracts before launch?
Yes. I review your contracts for common vulnerability classes, access-control and upgrade risks, and give you a ranked list of findings with suggested fixes, then re-check your fixes. For protocols holding significant value, treat it as preparation for a formal audit, not a replacement.
Do you also build AI systems, or only crypto?
Both. I led backend architecture for Alara, an enterprise AI platform used by major banks: Python (FastAPI) microservices, Kafka/Redis event pipelines and GCP deployments. I also build AI features triggered by on-chain events.
How do we get started?
Book a free 20-minute call or send the contact form with a short description and budget. We agree on scope and milestones before any work begins.
How much does a project cost?
It depends on scope. Each service on the Services page has a starting price, and you get a fixed quote or milestone plan after the first call.
Can I hire you through Upwork?
Yes. You can hire me through my Upwork profile, or get in touch here first and we choose the setup that fits.
Have a contract, bot or backend to build?
Tell me what you are building. A free 20-minute call is enough to tell whether I am the right engineer for it, and what it would take.
