I am a Senior QA Automation Engineer and Scripting Specialist with 6+ years of experience delivering high‑quality solutions across web, mobile, and backend systems. My expertise spans Python, Java, JavaScript, TypeScript, and C#, and I design scalable automation frameworks using Playwright, Selenium, Cypress, Appium, K6, Jenkins, and JUnit. Beyond traditional QA, I bring a diverse portfolio of projects, from Shopify storefronts and Shop.app flows to AI annotation, model training, and data pipelines. I excel at performance testing, CI/CD integration, and DevOps practices, ensuring automation is not only functional but also production‑ready. My work includes advanced data processing (Pandas, SQL, Excel/Google Sheets, JSON, OCR, image/PDF conversion) and AI‑assisted automation that accelerates testing and improves accuracy.

I provide a long-running PHP Laravel developer team that ships SaaS, CRM, marketplaces and admin tools. 7,000+ hours worked, 200+ PHP Laravel developer projects delivered, 100% Job Success Score, Top Rated Plus. As COO I scope, plan and oversee every PHP Laravel developer engagement we sign. I qualify the brief, run discovery, match the right engineers and own commercial relationships. My team owns the code. Why hire my team: - 20+ years of PHP Laravel developer delivery - 200+ PHP Laravel developer, Full Stack Laravel, Laravel Vue and PHP React projects shipped - Long-term retainers (3 - 10+ years) The PHP Laravel developer team I run is a full PHP Developer and Backend Developer bench. Every PHP Developer on it works in Laravel, MySQL and Redis with RBAC, audit trails, Stripe billing, queues and WebSocket real-time, so when a client needs a PHP Developer or a Backend Developer who owns the data model and the API, that is the seat I staff. The Backend Developer side covers schema design, REST and GraphQL APIs, background jobs and Nylas, Mailgun and Stripe integrations. On the frontend my Vue.js Developer and React Developer engineers pair with that backend. A Vue.js Developer takes admin panels, dashboards and multi-tenant SPAs on Inertia.js, Vue 3 and Pinia; a React Developer takes SaaS dashboards, marketplaces and content platforms on React + Next.js. Laravel Vue is what we reach for when a project needs a clean PHP backend with a reactive SPA. PHP React is the go-to when Laravel pairs with React + Next.js, with react node services and a javascript developer mindset across both sides. Our Full Stack Laravel team owns systems end-to-end - a Laravel + PHP backend paired with a Vue or React frontend, MySQL, APIs and AWS. Clients hire a Full Stack Laravel team instead of splitting backend and frontend specialists. Adjacent Full Stack Laravel: full stack web developer rebuilds, full stack php delivery, python full stack developer pairings for data and AI, full stack developer ai and full stack developer react funnels. A lot of the work is line-of-business systems, so I also staff a dedicated CRM Developer and ERP Developer. A CRM Developer rebuilds messy spreadsheet-and-email workflows into a single Laravel CRM with pipelines, roles and reporting; an ERP Developer wires registration, billing, inventory, lab and back-office modules into one platform with shared RBAC and audit. We have shipped a clinic ERP with cashier, doctor and lab desks and a CRM rebuild that ripped out a legacy Gutenberg setup. The CRM Developer and ERP Developer seats sit on the same Laravel core. Above the role labels, every engineer is a Software Developer first. That Software Developer discipline - clean architecture, code review, predictable deploys, tests - keeps a multi-month build stable and is what a client really buys when they hire a Software Developer through me. Migrations the team handles often: ruby on rails moved onto Laravel + React or Laravel Vue, an android developer hand-off when a backend feeds a mobile app, a flutter laravel companion when mobile is on the roadmap, a wordpress developer track for storefront and CMS migrations, and php laravel react rebuilds for clients outgrowing a Gutenberg setup. Clients hire me when they need: - a PHP Developer or Backend Developer who owns the data model, API and infra - a Vue.js Developer or React Developer to pair with a Laravel backend - a CRM Developer for pipelines, roles and reporting on Laravel - an ERP Developer for registration, billing, inventory and back-office modules - a Software Developer team for SaaS, marketplace or CRM products - a Full Stack Laravel team that owns frontend, infra and deploys - a wordpress developer hand-off and a long-term web developer and website design partner Recent work my team shipped: - Identity-verification SaaS. Backend Developer + Full Stack Laravel. Laravel + Node.js real-time, MySQL + Redis. 4K+ DAU, 1M+ checks via Developer API. - Multi-currency Voting SaaS. Full Stack Laravel / PHP React. Laravel + MySQL, real-time vote locking, Stripe payouts. 2M+ users in 10 countries, $2.5M+ revenue. - Clinic ERP. ERP Developer / Backend Developer. React + Next.js, Laravel, Node.js, Redis, AWS. Registration, cashier, doctor, lab desks, 500 patients/day. - Education B2B platform. Vue.js Developer + React Developer. Laravel 8, Vue.js admin, React portals, CKEditor, Stripe. Hierarchical content editor, student seats. - CRM rebuild on Laravel. CRM Developer / PHP Developer. Legacy WordPress + Gutenberg ripped out, photoshop assets, photographer briefs and product photography pipelines re-routed into a custom Laravel CMS with Nylas and Stripe. The COO hat keeps multi-month delivery predictable. Need a PHP Developer, Backend Developer, Vue.js Developer, React Developer, CRM Developer, ERP Developer or Software Developer team that ships on time and stays long-term - let's talk.

The gap between "it works in testing" and "it works in production" is where good products quietly lose users. You have probably seen it happen. A payment quietly fails at checkout. An API call times out under real load. A plugin update breaks something that worked yesterday. A customer hits an edge case nobody saw coming. The demo looked perfect, but production had other plans. None of that means anything is wrong with your product or your team. It is just what happens when software grows faster than its testing. Reliability is not a last-minute add-on. It is built quietly into the product from the first line of code, and that is exactly the work I do. With 5 years of QA across Fintech and Healthtech, where a single missed test case meant a compliance risk or a lost transaction, I learned to build with reliability designed in from the first API call, not bolted on after things break. So what you ship actually holds up when real users, real money, and real load hit it. What you get: -Web apps in Next.js, Node.js, and Supabase that are built to scale, not just to demo -Custom WordPress plugins with API integrations that survive updates instead of breaking on them -AI integrations using OpenAI and ChatGPT API that hold up under real user load -End to end QA automation with Selenium and Playwright, so edge cases get caught before your customers find them -API testing for Fintech and Healthtech products, where a silent failure costs real money and real trust -WooCommerce and ecommerce builds with custom functionality, including checkout flows that just work Live products running in production with real users are linked in the portfolio section below, so you can see the standard before we ever talk. If you want something built right the first time, so it works in production and not just in a demo, let's talk.
