Senior Sylius/Symfony Developer for Existing E-commerce Platform Stabilization

I am looking for an experienced Sylius/Symfony developer or a small technical team to help take over and stabilize an existing e-commerce project and bring it to production as a simple live e-commerce MVP. The project is Electrocruze, a gaming & IT e-commerce platform built on Sylius 2.2.1 / Symfony 7.4. This is not a greenfield project. I do not want a full rebuild unless the existing codebase clearly proves that stabilization is not commercially or technically reasonable. The immediate goal is simple: Take the existing project and make it live as a functional e-commerce shop. The long-term vision is larger, but it is not the scope of the first phase. The platform already has: * VPS Ubuntu 24.04 setup * Docker + Coolify deployment * Bitbucket repository * Sylius admin * Supplier import pipeline * Product catalog * Products, variants, stock, prices, images and attributes * Custom modules started for marketplace/ads and supplier management Current stack: * Sylius 2.2.1 * Symfony 7.4 * PHP 8.3 * MySQL * Docker + Coolify * Twig + SCSS + Stimulus/Webpack * Bitbucket * Ubuntu VPS Current status: * Around 13,000 products imported * Target catalog can grow much larger over time, potentially toward 250,000 products * Supplier integrations exist but need stabilization and correction * Pricing exists but needs correction; some products have price 0 * Frontend exists but needs UI/UX, responsive, PDP/listing/checkout improvements * Technical SEO is not fully implemented/validated * Payments, shipping, taxes/VAT and transactional emails still need configuration * Marketplace/ads module is started but is not part of the first live MVP I already have: * Verified full backup, around 11–12 GB * Bitbucket repository with history * Internal technical review / audit summary * Access to server, Sylius admin and Coolify * Known issues and priorities Important commercial clarification: I am not looking to start with a separate paid audit, paid discovery, paid validation or paid planning phase. I already have an internal technical review and known issues. What I need now is a practical preliminary implementation estimate for taking the existing project to production as a simple live e-commerce MVP. The first paid phase should be real stabilization / implementation work toward the live MVP, not another audit. I understand that no estimate can be perfect without deeper review. However, I need a realistic preliminary implementation range based on the project description and available information before deciding who to continue with. If the preliminary estimate and approach are aligned, I can provide controlled access after NDA: 1. Existing internal audit summary. 2. Read-only Bitbucket access. 3. Staging/test environment access if needed. 4. No production changes without explicit approval. 5. No direct production deployment rights at this stage. First live MVP scope: Please estimate only the work needed to reach a simple live e-commerce shop. Include: * Stable product catalog * Categories / taxons * Product variants * Correct prices and stock * Product images * Product listing pages * Product detail pages * Cart * Checkout * Payment configuration * Shipping configuration * VAT / tax configuration * Transactional emails * Supplier import stabilization at MVP level * Basic technical SEO * Safe staging-to-production deployment Please exclude from the first MVP: * Marketplace / ads module * Second-hand / resigilate module * PC Builder * Loyalty / rank system * Academy / courses * eSports * Job board * Community features * Complex promotion automation * Any long-term platform features that are not required for a simple live shop What I expect from you: Please apply only if you have real Sylius/Symfony e-commerce experience. Experience with supplier/API catalog imports is very important. Experience with Sylius Product, ProductVariant, ChannelPricing, Taxon and Attributes is important. Experience with Docker deployments is important. Experience with Twig, SCSS and Stimulus is useful because this is not a React frontend. Please include in your application: 1. Sylius projects you have worked on. 2. Symfony versions you have experience with. 3. Experience with supplier/API imports or large catalogs. 4. Experience with Sylius Product, ProductVariant, ChannelPricing, Taxon and Attributes. 5. Experience with Docker/Coolify or similar deployment setups. 6. Your preliminary estimate for taking the existing project to a simple live e-commerce MVP. 7. Estimated hours/range and cost range. 8. What is included in your estimate. 9. What is excluded from your estimate. 10. What your first real implementation/stabilization sprint would include. 11. Your availability over the next 2–4 weeks. Please do not apply if your only proposal is to start with a separate paid audit/discovery/planning phase before giving any preliminary implementation estimate. I prefer a phased, transparent collaboration with clear deliverables and controlled costs, but the first paid work should move the project toward production, not repeat an audit from zero.
