Ramy D.

Senior full-stack engineer and technical lead. I take prototypes, AI-generated codebases, and stalled systems to production, and I own them end to end: architecture, backend, frontend, mobile, DevOps, and security. Top 1% on Upwork & Top Rated Plus, 100% Job Success, $400K+ earned across 127 projects. Most of my clients are not looking for someone to take tickets. They have a product that exists in some form: a dashboard built with an AI coding tool that looks finished and is not, a platform the last team left half-built, or a system that works in a demo and breaks on real data. They need one senior person who can assess what is there, decide what to keep, and ship the rest with discipline: schema, business logic, API, UI, tests, deployment, monitoring. That is the work I do. I have inherited codebases from departed teams and taken them to production. I architected and ran a Layer 1 blockchain hardened with post-quantum cryptography, with 79 servers in production and a team of 30+ engineers under me. I built an executive digital twin, an AI agent that acts on a leader's behalf and delivers outcomes like a real hire. I put real estate on-chain for one of the top-producing teams at the world's largest real estate franchise. And I have shipped multi-tenant platforms where one customer's data cannot leak into another's. WHAT I BUILD - Full-stack SaaS: Next.js / React / TypeScript, Node.js, Python, Go, Rust, and PostgreSQL, delivered as complete vertical slices with tests - AI agents and automation: multi-agent systems, LLM integration, RAG, tool calling, structured outputs, evaluation, and agents wired into CRMs, inboxes, and internal tools - Mobile: iOS and Android apps, cross-platform, from setup through App Store and Play Store release - DevOps and infrastructure: AWS, DigitalOcean, Docker, CI/CD, monitoring, alerting, and incident response on systems that cannot go down - Security and regulated data: audits, hardening, authentication and RBAC, audit trails, and compliance-aware architecture for fintech. Certified Blockchain Auditor - Blockchain and smart contracts (EVM and Solana): protocols, DEXs, tokenization, staking, third-party audited - Technical leadership: assessing existing code and teams, prioritized roadmaps with real estimates, pull-request discipline, and directing other developers SELECTED WORK - Post-quantum Layer 1 blockchain, live on mainnet: architecture, validator operations, a decentralized exchange and staking platform, and live security incident forensics as fractional CTO - On-chain property registry for a principal of Keller Williams' #1 Philadelphia team (15,000+ homes sold, $4B+ in sales): ERC-721 on Base, email sign-in and dollar payments over real on-chain rails, private deeds with public fingerprints, and automated deed retrieval from city records - Executive digital twin: an AI agent built to operate on a leader's behalf across their tools and deliver finished work, not suggestions - Autonomous multi-channel AI sales agent: lead scoring, reply classification, CRM sync, inbox monitoring, and auto-response, running live outbound - Founding AI Engineer for a holding company building vertical AI agents - Multi-chain DeFi yield platform (including Solana), third-party audited, with an AI advisor layer - AI-driven portfolio intelligence platform, built end to end for a client - Lock-to-Earn digital wellness mobile app, founded and shipped on iOS and Android HOW I WORK - Assessment before rebuild. I do not rewrite from scratch because it is easier to bill. I tell you what to keep, refactor, or replace, and why - AI-native, not AI-sloppy. I use Claude Code and similar tools aggressively for speed, and I hold the line on tests, security, and data integrity - Small, documented pull requests, weekly priorities, and tradeoffs explained in plain language to leadership - I can bring in a vetted team when a project needs more hands, without agency overhead Consultations are free of charge. If you have a system that needs to reach production, or a team that needs a technical lead who still writes code, message me with what you are trying to ship and what is standing in the way. I will tell you straight whether I am the right fit.
