I build the data systems behind marketing and operations decisions: tracking and attribution that actually reconciles, pipelines from your tools into BigQuery, and dashboards whose numbers hold up. Lately that includes AI agents: systems that read, decide, and act inside your stack, with a human in the loop where it matters. 80+ Upwork projects, 100% Job Success, Top Rated. Before freelancing full time I spent five years at a global IT services group, first running SAP production operations for a global beauty retailer, then automating those same processes with UiPath. That automation programme took the operations team from 21 technicians to 8. Most of my work is one of four things. Fixing broken tracking and attribution, so lead source and conversions match across your site, forms, CallRail, CRM and Google Ads. Consolidating scattered data into a BigQuery warehouse with clean reporting on top. Automating the manual reporting and data entry that eats your team's time. Or building an AI agent for a bounded job: reading and routing inbound email and documents, or turning your numbers into a written summary that explains what moved and why. What I build - AI agents (Claude, GPT): email and document triage that extracts, tags and routes; reporting agents that query your data and write the plain-language summary; built with human review where it matters - Marketing tracking & attribution: GA4, Google Tag Manager, Google Ads offline and enhanced conversions, Meta CAPI, GCLID capture, CallRail, CRM event mapping - BigQuery data warehouses: ingestion from GA4, Shopify, ad platforms and APIs, modeled with SQL (dbt/Dataform) into clean, documented tables - KPI dashboards in Looker Studio and Power BI (executive, marketing, finance, ops) - Workflow automations with n8n, Make and Zapier: data syncs, alerts, validations, email and attachment parsing - Automated Google Sheets and Excel systems (advanced formulas, Apps Script, VBA) - Internal tools for tracking, forecasting and analysis Tools & platforms - AI: Claude API, GPT, prompt design, LLM document parsing - BI: Looker Studio, Power BI - Warehouse & data: BigQuery, dbt/Dataform, REST APIs, webhooks, CSV pipelines - Automation: n8n, Make, Zapier, Google Apps Script, UiPath (enterprise RPA) - Spreadsheets: Google Sheets, Excel (advanced formulas, Apps Script, VBA) - Marketing & analytics: GA4, Google Tag Manager, Google Ads, Meta Ads, CallRail, Shopify, HubSpot - Other: Airtable, Softr, Smartsheet, Monday com Typical use cases - An agent that reads inbound emails and PDFs, pulls out the fields, and updates the CRM or sheet automatically - Fixing attribution so lead source, GCLIDs and conversions reconcile across web, forms, CallRail, CRM and Google Ads - Marketing performance dashboards: spend, CAC, ROAS, funnel, by channel - Financial tracking: revenue, margins, forecasts - Consolidating multiple sources into one warehouse and one source of truth - Replacing manual reporting with automated workflows How I work - Structured and detail-oriented - I work through written communication: clear specs, Looms and documentation - I build simple, maintainable solutions, not over-engineering - I document what I build so your team can run and extend it If you want someone to own the data side end to end, from raw inputs to reporting you can rely on, send me your setup and where it is breaking and I will tell you where I would start.

Hi, I'm Alex - a Senior WordPress/WooCommerce Developer specializing in peptide and research-compound eCommerce stores. I build, rebuild, and optimize peptide stores end-to-end: design, WooCommerce setup, high-risk payment gateway integration, and — as part of every build — WordPress Speed Optimization to hit 98–100% PageSpeed Insights scores and pass Core Web Vitals. Slow WordPress sites lose visitors, hurt SEO, and cost you money — and peptide stores are especially vulnerable, with heavy catalogs, compliance widgets, COA/lab-result pages, and high-risk gateway scripts all stacking up. Even with WP Rocket, fast hosting, and optimization plugins, many sites still underperform. That's where my expertise in WordPress JavaScript optimization, performance tuning, and real-world Core Web Vitals fixes comes in — built into how I build every peptide store from the ground up, and applied to any WordPress/WooCommerce project that needs it. 🚀 What I Do Peptide eCommerce (my core focus) ✔ Full WooCommerce builds for peptide & research-compound brands ✔ High-Risk Payment Gateway integration (Authorize.net, NMI, and other high-risk processors) ✔ Multilingual / WPML builds for international peptide brands ✔ Compliance-aware UX (age-gate, disclaimers, COA pages) without sacrificing speed WordPress Speed Optimization (for any WP/WooCommerce site) ✔ WordPress Speed Optimization — reduce load times, optimize WordPress JavaScript, improve mobile and desktop performance ✔ Core Web Vitals Optimization — LCP, CLS, INP fixes aligned with Google ranking factors ✔ PageSpeed Expert Audits — deep performance analysis using GTmetrix, PageSpeed Insights, and Google Search Console ✔ WP Rocket Configuration — advanced caching, CSS/JS optimization, lazy loading (configured to not break checkout, gateway, or compliance scripts) ✔ Mobile Speed Optimization — mobile-first Core Web Vitals improvements ✔ WordPress SEO Performance Optimization — speed-focused SEO enhancements ✔ eCommerce Speed Optimization — WooCommerce performance tuning for high-SKU catalogs ✔ Elementor Speed Optimization — reduce builder bloat and improve rendering ✔ Hosting & CDN Optimization — Cloudflare, SiteGround, server-level tuning ✔ Ongoing Speed Maintenance — continuous monitoring and optimization 🛠 My Approach as a PageSpeed Expert 1️⃣ Performance Audit — full audit using GTmetrix, PageSpeed Insights, and Google Search Console 2️⃣ Technical Optimization — WP Rocket, caching, database cleanup, image optimization, CDN setup 3️⃣ Core Web Vitals Fixes — real improvements for mobile and desktop 4️⃣ Testing & Validation — before/after testing with industry tools 5️⃣ Documentation & Handoff — clear report and recommendations I work with all types of WordPress projects: peptide & research-compound stores, WooCommerce stores in general, blogs, SaaS landing pages, agency websites, Elementor builds, and membership platforms — wherever performance, conversions, and SEO are critical. 📊 Results Clients Get 95–100% PageSpeed Insights scores Major Core Web Vitals improvements Faster load times (often 2–5 seconds faster) Better WordPress SEO and Google rankings Higher conversions and lower bounce rates Stable, scalable peptide stores that don't break under high-risk gateway or compliance requirements 🔧 Tech Stack & Keywords WordPress Speed Optimization | PageSpeed Expert | WP Rocket | Core Web Vitals | Google Search Console | WordPress JavaScript | WordPress SEO | GTmetrix | Mobile Optimization | Elementor Performance | WooCommerce Speed | Cloudflare | SiteGround | PHP | CSS/JS Optimization | Lazy Loading | CDN | Peptide eCommerce | High-Risk Payment Gateway | WPML ✔ Top Rated Plus WordPress & PageSpeed Expert ✔ 12+ years WordPress development experience ✔ 200+ WordPress sites optimized, including peptide & high-risk eCommerce stores ✔ Trusted by agencies, SaaS companies, and peptide/eCommerce brands If your WordPress or peptide store is slow — even with WP Rocket and good hosting — I'll fix it with real, data-backed optimizations. As someone deeply focused on peptide eCommerce and WordPress Speed Optimization, I work not just as a PageSpeed Expert, but also as a hands-on WordPress/WooCommerce Developer who understands how performance, code quality, high-risk payment flows, and real-world business goals connect — ensuring every build and every speed improvement is stable, measurable, and scalable.

A top 3% Upwork Senior Full Stack Developer - and your site is in expert hands. When you work with me, you keep full ownership of everything I build. I am a full stack developer, SaaS developer, and dashboard developer in the UK. As a full stack developer I own the entire stack — PostgreSQL design, Node.js and Nest.js backend, React and Next.js frontend, REST API integrations, Stripe payments, and Vercel deployment. Need a full stack developer, SaaS developer, or dashboard developer who owns the technical side end to end? Let's talk. My recent full stack developer work includes a SaaS platform for trades businesses — a Next.js app with job management, client records, quoting, and role-based access — and a B2B admin dashboard on PostgreSQL, Node.js, and React that a team of 20 depends on every day. Technical consultant. Architecture. Audit. For non-technical founders my tech stack and architecture audit with written report shows what you have, what's broken, and what to build next — vendor selection, developer estimate review, security review, and a roadmap. As a Next.js performance specialist I improve Lighthouse and Core Web Vitals — measurable gains for users and search ranking. SaaS developer. Multi-tenant. Production-ready. As a SaaS developer I delivered a multi-tenant SaaS starter on Next.js with Stripe subscriptions, PostgreSQL via Neon, role-based access, billing portal, and team invites — fully documented, repo transferred on handover. I led a platform rebuild from legacy PHP and WordPress to a modern Next.js and Nest.js architecture — 40% lift in user engagement post-launch. I also build multilingual B2B platforms — Next.js with Sanity CMS, localised content and routing, editorial workflows non-technical teams actually use. Security audit. Supabase RLS. Multi-tenant isolation. As a technical consultant I run pre-launch security audits for SaaS founders — the review that must happen before real customer data goes live. My audits cover Supabase Row Level Security (RLS), multi-tenant isolation, PostgreSQL policy design, authentication flows, and exposed API keys in client code. I've audited a multi-tenant property maintenance SaaS on Supabase, and on another platform found RLS policies that lived only in discarded migrations, never applied to the database — the silent data leak an audit catches before a breach. If you're a SaaS founder on Supabase, Next.js, or PostgreSQL and aren't certain your tenant data is isolated, that's the audit I do. Backend developer. Nest.js. PostgreSQL. Data pipelines. As a backend developer I build production Nest.js and Node.js APIs on PostgreSQL with TypeScript end to end. Recent backend work: a Nest.js and PostgreSQL backend for a raffle SaaS platform — JWT authentication, OAuth providers, password recovery, and a clean REST API layer for a Next.js and React frontend. I also engineered a web scraping and data aggregation engine: Nest.js cron pipelines with adapters for multiple third-party sites, anomaly detection, stale-data cleanup, and webhook alerting — thousands of records refreshed daily on Railway, Prisma, and Neon. Every endpoint authenticated, every role enforced, every query isolation-aware. Dashboard developer. AI features. Data that changes decisions. As a dashboard developer with a KendoReact commercial licence I build enterprise-grade interfaces standard React developers can't replicate — advanced data grids, real-time charts, complex forms under load. My portfolio includes a marketing analytics dashboard with AI insights that cut campaign review time by 60% for a British agency, and a SaaS analytics dashboard with Chart.js and PDF export that replaced weekly manual reporting. I integrate LLM APIs (Anthropic Claude, OpenAI) into production apps — AI insights, content pipelines, and matching features, keys secured server-side. Integrations. Authentication. Infrastructure. OAuth integration and API authentication — credential flows for Google, GitHub, and custom providers using NextAuth, Nest.js, and JWT. Google Tag Manager with GA4 and Meta Pixel across complex Next.js apps, GDPR cookie consent and Consent Mode included. Transactional email on Resend and Brevo, plus Next.js blog and CMS setup with Sanity Studio. Stripe. Payments. Automation. I built a Stripe internal payment interface with role-based access on Next.js — PaymentIntent flow, full audit log, zero card data stored. I delivered Stripe subscription billing with webhooks handling upgrades, downgrades, and failed payment recovery. I wire Stripe with Make, GoHighLevel, and Google Sheets so every transaction triggers the right email, CRM tag, and notification.

8 iOS apps live on the App Store — built solo, from architecture through App Review approval. If your app is half-built, stalled, or stuck in review, that's the exact problem I solve. WHAT I SHIP - iOS/macOS in SwiftUI (Swift 6 strict concurrency) — architecture to App Store approval - StoreKit 2 subscriptions and IAP that pass review (8 approvals, including Catalyst, watchOS, CarPlay) - FastAPI backends and Next.js/React frontends for the same product - Rescue work: half-finished codebases, rejected builds, abandoned repos PROOF YOU CAN CHECK IN 30 SECONDS Search "SwiftQuantum" on the App Store, or open ide.swiftquantum.tech. Everything I claim is running right now. WHY THE BACKGROUND HELPS My own products are quantum-computing tools — a 127-qubit circuit IDE, a post-quantum cryptography scanner (NIST FIPS 203). Building those alone is why ordinary product work moves fast for me, and why I catch edge cases early. Patent holder (AI systems). Excellence Award, Korea Open Data Forum 2024. 1st place, national startup competition. Former CTO of a product serving 10,000+ daily users. IEEE member, presenting at IEEE Quantum Week 2026 in Toronto. HOW I WORK Honest scoping — I'll tell you if something is a bad idea before you pay for it. Daily written updates. Nothing I demo is fake. Seoul time (UTC+9): you send feedback at end of day, you wake up to progress. Send me your spec, or even a rough idea. I'll reply with a plan, a realistic timeline, and what I'd cut to ship sooner.
