I build practical backend and Web3 integrations for APIs, dashboards, data pipelines, and automation workflows. I have 3 years of hands-on experience with Python and Node.js projects, REST APIs, databases, testing, monitoring, and production-oriented troubleshooting. I can develop Python and Node.js backend services, integrate REST APIs and webhooks, handle authentication and data processing, connect applications to blockchain and Web3 services, support wallet connectivity and transaction monitoring, work with smart-contract SDKs, and build market-data pipelines. I also work with PostgreSQL and SQLite, database schemas, audit logs, migrations, scheduled workers, automation scripts, bots, testing, debugging, validation, documentation, and deployment-ready setup. I focus on clean, maintainable code, clear communication, reproducible tests, and secure credential handling. I can work from an existing codebase or build a focused solution from a clear specification.

I perform a focused, local/devnet-first security review of smart contracts, wallet flows, payment/escrow logic, and Web3 APIs for Solana or EVM systems. Deliverables: - threat model and prioritized findings - deterministic local or devnet proof of concept where appropriate - severity/impact analysis and practical remediation - regression tests or a focused patch when the codebase is available - concise evidence package with hashes and reproduction steps I do not request private keys, custody funds, use social accounts, or test live funds without explicit written authorization. Work is milestone-based and can start with a small scoped review. Fixed-price packages start at 200 USDC, with escrow before implementation.

I will test one focused web or API workflow and deliver a concise defect report plus reproducible automated checks in Python/pytest or TypeScript/Playwright. The starter engagement is designed for a fast first milestone: acceptance criteria review, happy-path and negative-path coverage, minimal reproductions for valid defects, and a final evidence summary with exact commands and results. Ideal for FastAPI, REST APIs, Next.js/React flows, CLI tools, and data-integrity checks. Public examples: https://github.com/atlascraft-codex and https://atlascraft-codex.github.io/google-adk-memory-migration-showcase/#demo. Introductory pricing is available for a small, escrow-funded trial while I build Worqen reputation; no production credentials are required unless explicitly agreed.

I turn an existing API into clear, testable OpenAPI 3.x documentation and a practical security test plan. This is a focused fixed-scope engagement for teams that need a fast handoff rather than a large blockchain build. For a 200–400 USDC milestone I can deliver: • an OpenAPI spec or cleanup of an existing spec; • endpoint, schema, auth and error examples; • route and permission inventory; • reproducible checks for broken access control, replay/nonce handling, rate limits, input validation, webhook and RPC assumptions; and • a prioritized remediation checklist with acceptance criteria. Where appropriate I can include a small read-only or local/devnet proof of concept. I document assumptions, keep secrets out of test artifacts, and never request private keys, bypass CAPTCHA, or test live funds without written authorization. Escrow is required before paid work begins. Public portfolio: https://github.com/xordanx/arc-security-research https://github.com/xordanx/solpulse-report https://github.com/xordanx/jup-risk-gated-dca https://github.com/xordanx/zeroclaw-solana-payout-guardian Available now for a reviewable 200–400 USDC milestone.

I provide a focused, reproducible security and integration package for Solana/Web3 products, agents, games and APIs. I review wallet and transaction flows, token/payment logic, authorization boundaries, replay/nonce handling, webhook and RPC assumptions, and smart-contract/API interaction risks. Deliverables are agreed up front and can include: • architecture and threat model; • read-only or devnet-first proof of concept; • OpenAPI 3.x documentation and endpoint examples; • local regression tests with exact reproduction steps; • prioritized findings with remediation guidance; and • a concise deployment/runbook handoff. I use Solana RPC/SPL and can keep the design chain-agnostic when an EVM boundary is required. I do not custody client keys, bypass access controls, or test live funds without explicit written authorization. Paid work is milestone-based with escrow funded before implementation. Public portfolio: https://github.com/xordanx/arc-security-research https://github.com/xordanx/solpulse-report https://github.com/xordanx/solana-loyalty-rewards-challenge https://github.com/xordanx/jup-risk-gated-dca https://github.com/xordanx/zeroclaw-solana-payout-guardian Available now for a fixed-scope review, integration plan, or security handoff. Typical engagements: 500–1,500 USDC, with smaller 200–400 USDC API documentation/test-plan packages available on request.
