I built the ad-operations platform behind 20,000+ Meta ad launches a month at a company doing $100M+ a year. I build that kind of system for founders and small teams: AI automation, internal tools, and production software on Node.js, React and AWS.
Selected production work:
- Automated video creative production for a 30-person design team producing 600+ assets daily, cutting per-creative editing time from 20–25 minutes to 5–7 with parallel batch processing.
- Automated monthly invoicing for 200 people, eliminating 2 days of manual work per cycle.
- Shipped and supported 70+ production automations across one company's operations.
- Owned application development for a B2B SaaS that reached 30+ active brands in three months.
Founders hire me to:
- Replace spreadsheet-heavy operations and manual handoffs with production systems
- Build internal tools that non-technical teams can actually operate
- Launch an MVP that can evolve past the prototype stage
- Integrate subscriptions, checkout, webhooks, or usage-based billing
My approach is straightforward: identify the business outcome, cut the first release to the smallest valuable production slice, surface risks early, and deliver in demonstrable milestones.
I work UTC+8, with daily overlap for European and APAC mornings and US calls in my evening. You get written end-of-day updates, so you always know where things stand.
Send me your current process or product, the outcome you want, and your deadline. I'll come back with the smallest sensible first milestone, the assumptions I'm making, and the risks I see.

I build SaaS products and Chrome extensions using Next.js, Supabase, TypeScript, and React.
Most of the products I work on start as MVPs but are expected to grow, so I think about authentication, billing, permissions, and maintainability from the beginning.
I usually work with founders who already have a product idea and need someone who can take ownership of the technical side of implementation. That might mean building a system from scratch, improving an existing codebase, or cleaning up a prototype that has become difficult to maintain.
Some of the work I’ve done recently:
- Building full-stack SaaS applications with authentication, file uploads, Stripe billing, dashboards, and AI-powered functionality
- Developing Chrome extensions connected to SaaS backends through secure authentication, background processing, and data synchronization
- Refactoring large Next.js applications to improve SEO, SSR, caching strategies, and long-term maintainability
- Designing Supabase systems involving Auth, PostgreSQL, Row Level Security (RLS), Storage, and server-side logic
- Improving search and filtering performance through query optimization and server-side rendering
- Integrating third-party services such as Stripe, OpenAI, and Podio into existing products
Technologies I work with regularly include Next.js, React, TypeScript, Supabase, PostgreSQL, Stripe, Vercel, OpenAI API, Chrome Extensions (Manifest V3), REST APIs, serverless functions, SSR, caching strategies, and role-based access systems.
If you're ready to hand off the technical heavy lifting and focus on growth, drop me a message and let's map out your roadmap.

As a WordPress developer and WooCommerce developer I build custom WooCommerce plugins, migrate WordPress sites off page builders, and run WordPress speed optimization - without breaking the revenue that depends on them.
If your WooCommerce store is slow, stuck on Elementor, Divi, WPBakery or Crocoblock, or failing Core Web Vitals - that's the work I handle every day as a WordPress developer and WooCommerce developer.
10+ years as a WordPress WooCommerce developer - Top Rated, 100% Job Success - working on live WordPress and WooCommerce sites that can't afford downtime.
WOOCOMMERCE DEVELOPMENT
Custom WooCommerce plugin development in PHP. As a WordPress plugin developer and WooCommerce plugin developer: custom hooks and filters, admin tooling, REST API endpoints, WooCommerce checkout customization, custom checkout fields, payment gateway troubleshooting (Stripe, PayPal), product catalog and inventory logic, supplier price and stock sync, and third-party API integrations (CRM, ERP, shipping).
I also handle WooCommerce Subscriptions, WooCommerce Bookings, memberships, product bundles, B2B and wholesale pricing, and multilingual WooCommerce stores (WPML). I build and maintain custom WordPress plugins inside proprietary codebases - not just off-the-shelf configuration. Git-based workflow, staging first, clean maintainable WooCommerce development.
WORDPRESS MIGRATION
WordPress migration, done without breaking things: I move sites off Elementor, Crocoblock (JetEngine, JetSmartFilters, JetMenu), Divi and WPBakery page builders onto clean, native WordPress - Gutenberg, Full Site Editing (FSE), theme.json, template parts and reusable patterns. Elementor to Gutenberg migration, page builder to block theme rebuilds, classic theme to FSE, and website migration between hosts with SEO preserved (301 redirects, meta, structured data).
I move custom post types, ACF and JetEngine fields, taxonomies and relationships to a native content model, and rebuild faceted filters and search (FacetWP), mega menus, TablePress tables and multilingual setups (WPML, Polylang) - including Elementor WooCommerce sites. As a WordPress theme developer I rebuild the design as a native block theme: lighter, faster, easier to maintain, and API-ready if you ever go headless.
WORDPRESS SPEED OPTIMIZATION
WordPress speed optimization and WooCommerce speed optimization: Core Web Vitals (LCP, INP, CLS), PageSpeed Insights and GTmetrix scores, page speed optimization, TTFB reduction, Redis object caching, edge and CDN caching (Cloudflare, AWS CloudFront), WP Rocket and LiteSpeed configuration, image optimization and WebP, database and slow-query optimization, plugin bloat audit. I find and fix the real bottleneck - server, database, WordPress theme or plugins - not just install another cache plugin.
AI SEARCH AND AUTOMATION
Where AI genuinely pays off, I add it: semantic search and recommendations across your WordPress and WooCommerce content, AI sales-agent chatbots, and automation of repetitive store operations - on your own infrastructure, with an API-ready content model that keeps a headless future open.
RECENT WORK
- Built a custom WooCommerce Dokan plugin (price-decay engine) - "flawless architecture, clean, modular and optimised for performance."
- Rebuilt a trading-education platform (~15M monthly visits) from a page builder to a custom WordPress theme, as team lead of 4 developers. WordPress speed optimization took PageSpeed from 25-35 to 95-100.
- "Page performance is now 100/99 (desktop/mobile)" - a WordPress and WooCommerce Page Speed Optimization client.
- Built a custom AI sales-agent WooCommerce plugin for a live store: product search, cart actions, admin UI, REST API, LLM integration.
- Two WooCommerce stores on one server: homepage 2.01s to 0.07s, 95% of traffic answered before it reached the origin.
HOW I WORK
My rule: a live WordPress site is treated as live. Staging first, clear scope and milestones, and you see changes before they go near production. Honest estimates, updates every couple of days - one-off projects or ongoing maintenance and support.
WHO THIS IS FOR
WooCommerce store owners and ecommerce teams who want their store faster and more dependable. Companies moving off Elementor, Divi or Crocoblock to a clean, native WordPress setup, built by a WordPress developer who knows WooCommerce inside out - from WooCommerce website development to custom plugins.
Skills: WordPress, WooCommerce, WordPress migration, WordPress speed optimization, Core Web Vitals, PHP, MySQL, REST API, custom WordPress plugin development, Elementor, Gutenberg, Full Site Editing, ACF, FacetWP, WPML, WooCommerce Subscriptions, WP Rocket, Redis, Cloudflare, WordPress theme development, WordPress theme customization, Github.

I'm a UI/UX Product Designer who ships, not just designs. 400+ projects, $500K+ earned, Top Rated Plus - your product can be live this week, not just as a Figma file! 🚀
I design in Figma, then build the real thing myself with Claude Code, Cursor and Framer.
SaaS dashboards, web app design, B2B platforms, landing pages - built and deployed, not just clickable prototypes. You skip the design-to-dev handoff entirely or I hand off clean documentation if your team takes it from there
Trusted by Creednz ($7M seed, Blumberg Capital), Dopavision (€14.7M, Novartis), and Americanflat (Target, Amazon, Wayfair) - see how below 👇
‣ Why this works for your product:
Most UI/UX designers stop at wireframes and hand you to a developer.
I run the whole flow as a product designer: UX research, user flows, information architecture, wireframing, high-fidelity UI in Figma, prototyping. Then AI-assisted development with Claude Code, Cursor and Framer. Projects that used to take months now ship in week
SEO and GEO (generative engine optimization, so you show up in AI answers like ChatGPT and Perplexity) get built in from the first wireframe
If you need a fast MVP or a landing page live this week, that's the whole point of working with me. If the timeline is tight, I can turn around a scoped, working solution fast
‣ What I design & buid:
SaaS and B2B product design - dashboards, complex platforms, admin panels, from discovery through production-ready UI
MVP design and development - landing pages and web apps built, not just designed. Figma to Claude Code, Cursor, Framer, or Figma Make, live fast
Design systems in Figma - auto-layout, variables, component libraries, dev handoff docs for teams that build in-house
Mobile app design (iOS and Android) and mobile UI UX for e-commerce - Shopify, Webflow, WordPress - when it's part of the same product
AI-generated creative content - product photography, social content, and campaign imagery I generate and art-direct myself, reviewed and refined, not shipped raw out of a model
Product audits - UX, UI, usability testing, accessibility (WCAG), SEO/GEO readiness, and AI-readiness reviews of your existing site or app. What's broken, what's costing you conversions, and what's blocking a faster AI-assisted rebuild, with a prioritized fix list, not just a slide deck
‣ Some achievements:
400+ projects completed & 100% Job Success Score
Top Rated Plus
Clients across the US, DACH, Israel, the Gulf & Australia
‣ Tools:
Figma, Figma Make, Claude Code, Cursor, Framer, Webflow, Shopify, WordPress
‣ How it works (pretty fast tbh):
1) Discovery call first
2) Scope and timeline in 24 hours
3) Milestone-based delivery
4) 2 revision rounds
5) Figma handoff with a Loom walkthrough on completion
6) Rush timelines accommodated when the project needs to move fast
