I’ve driven +50% net revenue growth, 4x ROAS, and 0.7%→2.5% CVR as a growth operator and ex-CGO at a premium lifestyle subscription brand. 30+ clients across 7 and 8-figure DTC, SaaS, and subscription businesses. Results are verified – Clutch 5.0, CEO-signed. I can see things that others don’t (in the data, not losing my mind). You’re running a $1M–$10M eCommerce or SaaS business. Growth is working – but it’s getting more expensive and less predictable. You’ve tried agencies. You’ve tried freelancers. Someone increased your CVR and your revenue didn’t move. Someone ran ads and ROAS looked great until you checked MER. You’re not sure who to trust anymore – and you’re right to be skeptical. That’s exactly where I come in. I’ve seen what happens when conversion rate gets optimized in isolation – LTV drops, MER deteriorates, and the business looks better on paper while quietly losing efficiency. Most growth people optimize the metric you asked for, not the business behind it. I don’t work that way. Every engagement starts with a revenue audit – finding the real constraint before touching anything. Then everything runs through a structured Growth Growth Experimentation Framework: every hypothesis across acquisition, retention, pricing, or conversion is data-driven, ICE-scored, and tied to measurable outcomes – RPV, CVR, CAC, and ROAS – with the full system oriented toward LTV and MER over time. Not random tests. Not isolated wins. One connected experiment engine where every decision compounds. I take 1–2 clients per month – not because of availability, but because this work requires full attention to produce results worth paying for. Verified results: → +50% annual net revenue growth → LTV +50% through cohort identification and activation → ROAS 0.75 → 4x while scaling paid spend → +16.9% ARR | +25% paid subscribers in 3 months (SaaS) → Conversion rate 0.7% → 2.5% across core funnel → +80% CVR uplift on main product page What I cover: → Full-funnel CRO and structured experimentation → Revenue analytics: LTV | CAC | MER | RPV | cohort modeling → BigQuery | Looker Studio | GA4 | PostHog | GTM → Shopify subscription and monetization (Recharge | Loop | Klaviyo) → Paid acquisition efficiency: Meta | Google → SaaS activation | pricing | product-led growth → AI-powered reporting and experimentation workflows Who I work with: 7 and 8-figure eCommerce and SaaS – DTC, B2B, CPG, and subscription. Credentials: → Clutch 5.0 (CEO-verified) | Top Performance Marketing Company 2025 → CXL Certified CRO | AIPMM Certified Product Manager | MBA → 30+ clients | 100% Job Success Score If your growth has plateaued and you’re not sure why – that’s exactly the problem I solve. Let’s find it in the first conversation.​​​​​​​​​​​​​​​​

Every technological revolution has expanded human capability by offloading cognitive work. Writing externalized memory. The printing press democratized literacy. Today, AI, cloud computing, and open-source software are doing the same for software development. I help founders bridge the gap between abundant technology and scarce cognitive bandwidth and implementation capability. As the solo developer behind y2map(dot)com, I design systems that minimize recurring costs, technical debt, and operational complexity so businesses can spend less time maintaining software and more time improving products, serving customers, and making better decisions. What I Optimize: 1. Cognitive bandwidth by replacing repetitive work with automation and better workflows. 2. Technical debt through simple architectures, modern frameworks, and proven open-source libraries. 3. Monthly burn by reducing unnecessary SaaS subscriptions and designing cost-efficient infrastructure. 4. Decision making by building data pipelines, dashboards, and AI workflows that surface actionable insights instead of information overload. 5. Founder leverage by creating systems that require less maintenance and compound in value over time. The objective is reducing cost and complexity. With the rise of AI, more teams are moving key functionality in-house. Whether that means replacing an expensive SaaS subscription with an open-source alternative, designing an architecture that minimizes future maintenance, building an internal automation, or creating analytics that improve business decisions, every recommendation is guided by one question: Will this save time, reduce mental effort, and compound over the next five years? You can expect clear communication, thoughtful trade-offs, rapid iteration, and software designed not only to launch quickly—but to remain maintainable, affordable, and valuable long after version one.

A good developer builds what you asked for. A great one builds what your product still needs six months from now, when your first version isn't enough anymore, your users have multiplied, and every new feature has to fit into something that was actually built to last. When the foundation is built right the first time, every feature after it gets easier to add instead of harder. Your app stays fast as your users grow, your codebase stays welcoming to any developer who joins the project later, and your launch date stays a promise you can actually keep instead of a guess you're hoping pays off.. That is the problem I solve. My work centers on Next.js, paired with React, NestJS, and Node.js on the backend, PostgreSQL for data, and Docker and AWS for deployment, all wrapped in TypeScript for a codebase that stays maintainable as it grows. Recent work includes architecting a multi-dashboard SaaS platform, eight separate dashboards running under one domain with shared single sign on, a shared database, and shared navigation, so the whole system behaves like one product instead of eight disconnected ones. I have also built an Office add-in for Word and Outlook using React, TypeScript, and Fluent UI, migrating an entire legacy add-in off older C# technology into a modern stack, complete with custom ribbon actions, custom Outlook fields, and a rich text editor built in. On the automation side, I have built a WhatsApp based AI ticketing system for handling incoming reports, where AI reads and responds to messages, creates tickets automatically, places calls to contractors when needed, and even analyzes photos to detect emergencies and flag urgency. I have also built an information platform that pulls data from multiple third-party services into a single place, so a business can see everything without switching between tools. On the infrastructure side, I design network topology and manage AWS servers directly, including database and web server setup, so projects run reliably. On Upwork: 100% Job Success Score.

I build production-grade AI agent systems, automation infrastructure, and DeFi/blockchain solutions for startups and protocol teams the kind that run reliably in the real world, not just in demos. My work spans AI agent development (Claude / Anthropic APIs, Claude Code, Claude Agent SDK, MCP tool integrations), workflow automation (n8n, Make, webhook-driven pipelines, REST/API integrations), and DeFi infrastructure (FLASH LOAN ARBITRAGE BOTS, MEV- SHIELDED EXECUTION, LIQUIDATION KEEPERS), built in Python, TypeScript, Rust, and Solidity, deployed across Ethereum, Arbitrum, Polygon, and Solana. What I deliver: AI agents that take real action tool use, multi-step workflows, browser automation (Playwright), CRM/API integrations, with guardrails and human-in-the-loop approval for high-impact actions Automation systems built with n8n/Make or custom Python/TypeScript runtimes, wired to REST APIs and webhooks Flash loan arbitrage & liquidation bots (Aave V3, Compound, Euler), MEV-aware execution with Flashbots Protect Full-stack delivery: FastAPI/Node.js backends, React front ends, AWS deployment Machine learning-backed decision layers where they add measurable value not just an LLM bolted onto an API call Every system I ship is production-tested, documented, and built with clear permissions, error handling, and logging so your team can actually maintain it, I don't build things that only work 70% of the time. If you're working on an AI agent product, an automation pipeline, or a DeFi protocol and need an engineer who can move fast without cutting corners, let's talk.
