Alexander P.

Senior Laravel Developer & SaaS Architect | B2B Integrations

I architect, build, modernize, and take long-term ownership of business-critical Laravel SaaS products, custom CRM/ERP systems, and integration-heavy B2B platforms. With 15+ years in software development and 200+ projects delivered worldwide, I have taken products from business requirements and data architecture through hands-on development, infrastructure, launch, and production support. Some systems I built more than a decade ago are still supported and evolving today. Clients hire me when a product is too complex for fragmented technical ownership: multiple companies and user roles, approvals, payments, documents, real-time collaboration, large data flows, or several external systems that must work reliably together. I understand the business process, make the architectural decisions, write production code, and remain accountable after launch. 𝗦𝗘𝗟𝗘𝗖𝗧𝗘𝗗 𝗣𝗥𝗢𝗗𝗨𝗖𝗧𝗜𝗢𝗡 𝗦𝗬𝗦𝗧𝗘𝗠𝗦: • Fleet operations platform — Built for a New York client and running in production for 5+ years. It brings vehicle rentals, contracts, recurring charges, Stripe Connect and ACH payments, owner payouts, maintenance, and operational reporting into one system. • Secured-lending operations system — Manages the complete workflow around property-backed loans: borrowers, collateral, DOCX/XLSX documents, external registry checks, background processing, audit trails, and real-time project updates. • Marketplace operations platform — Automates twice-daily synchronization of product data, prices, and inventory from a source ERP to multiple seller accounts, reconciles differences, and updates only what has changed. • Legal-services ecosystem — Combines client intake, expert profiles, project workspaces, protected payments, document generation, real-time chat, CRM integration, and structured OpenAI-assisted answers. 𝗪𝗛𝗘𝗥𝗘 𝗜 𝗖𝗥𝗘𝗔𝗧𝗘 𝗧𝗛𝗘 𝗠𝗢𝗦𝗧 𝗩𝗔𝗟𝗨𝗘: • Architecture and end-to-end delivery of new Laravel SaaS and B2B products • Custom CRM/ERP, operational back-office systems, portals, dashboards, roles, approvals, and workflows • REST APIs, payments, webhooks, banking and third-party integrations • AI/OpenAI features, automated documents, large imports, queues, search, and real-time functionality • Stabilization, performance work, and modernization of existing PHP, Laravel, Yii, and JavaScript systems • Flutter applications that extend an existing web platform to iOS and Android 𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞: Clients work directly with me throughout the engagement. I convert business requirements into a coherent architecture, divide delivery into verifiable milestones, surface risks and trade-offs early, and keep progress and next decisions clear. I can start a product from zero, take over an existing codebase, or stay involved as the long-term technical owner after launch. 𝗖𝗢𝗥𝗘 𝗦𝗧𝗔𝗖𝗞: PHP 8.4, Laravel 13, PostgreSQL/MySQL, Redis, Vue 3, TypeScript, Inertia, Livewire, Filament, Tailwind CSS, REST APIs, OpenAPI, webhooks, Horizon queues, WebSockets, Stripe, Pest, Flutter, Linux/NGINX, CI/CD, and production observability. 𝗕𝗘𝗦𝗧 𝗙𝗜𝗧: I work best with established businesses, funded startups, and product teams that have a serious operational problem, a realistic budget, and a decision-maker who values direct, calm, professional collaboration. My work is priced for senior technical ownership rather than commodity implementation. The right clients hire me because avoiding poor architecture, fragile integrations, operational downtime, and repeated rebuilds is worth more than choosing the lowest initial rate. Send me the current state of your product, the business result you need, and the main constraints. I will identify the critical risks, recommend the most practical path forward, and propose a clear first milestone.
