Hire the Best FourSquare API Developers

You don't need someone to write code. You need someone who understands your business problem and delivers a backend that doesn't need to be rebuilt in a year. 6+ years working in PHP and Laravel across SaaS platforms, e-commerce systems, and custom WordPress backends. I've shipped 450+ projects and I maintain open-source Laravel packages actively used by other developers - that's not a line on a resume, you can read the code on GitHub before you hire me. What I actually work on: ✓ Laravel SaaS backends - multi-tenant architecture, billing integrations (Stripe, PayPal), job queues, real-time features with Reverb or Pusher ✓ RESTful and headless API development - versioning, authentication (Sanctum, Passport, JWT), third-party integrations, and passive contract monitoring so integrations don't silently break ✓ WordPress - custom plugins, hook architecture, WooCommerce extensions, REST API bridges between WP and Laravel systems ✓ Performance and refactoring - I regularly take over legacy Laravel codebases, add test coverage, resolve N+1 issues, and modernize to current standards without breaking production ✓ E-commerce - order pipelines, multi-channel inventory (Shopify, WooCommerce, Amazon, Etsy), payment gateway integrations A few things I've shipped publicly: Built a multi-channel notification engine for Laravel 12 with parallel dispatching and smart routing. A static analysis tool that catches dangerous migrations before they hit production. A passive API contract monitor that detects breaking changes in third-party REST APIs using probabilistic inference. These aren't portfolio pieces - they're tools other developers use. On working with AI: Yes, I use AI tools in my workflow. The difference between a developer who uses AI well and one who doesn't is knowing what to verify, what to question, and what to never let near production without review. My open-source work exists partly because I kept running into problems that AI-generated boilerplate can't solve. Who I work well with: Founders and technical leads who know what they want to build but need someone who can own the backend without constant hand-holding. If you have a spec, I'll ask the right questions and deliver clean, documented code. If you have a problem, I'll figure out the architecture. Available for fixed-price projects and ongoing contracts. Response time is fast - usually within 10 minutes

US-Based Principal Engineer | Zero Outsourcing | 25 Years in the Trenches I provide the technical certainty that only comes from longevity. With over 100 projects completed on Upwork and experience dating back to the earliest days of the web, I build robust backend architecture that works the first time. Current Featured Solution: Advanced Jobber & HubSpot Sync I recently developed a custom Python listener & PHp-based integration for the service industry that automates: Real-time Client Sync: (Create/Update) between HubSpot and Jobber. Job Lifecycle Automation: (Create/Update) via high-performance webhooks. If Zapier or native integrations are failing your workflow, I can build you a custom, resilient bridge. Core Expertise: Python & FastAPI: Modern, asynchronous, and strictly typed APIs. API Integration & ETL: REST, GraphQL, and legacy SOAP services. PHP & Backend Systems: Custom architecture, Laravel, and database optimization. Data Architecture: Custom SQL design and complex JSON transformations. Why Work With Me: You are hiring a Subject Matter Expert, not a junior developer. I do not outsource, I do not subcontract, and I do not require hand-holding. I translate business requirements into production-ready code that is documented and resilient.

Most SaaS, AI, and healthcare platforms do not fail because the first version cannot be built. They fail because the architecture, workflows, permissions, integrations, and scaling decisions were not planned properly from day one. I help startups, founders, and growing teams build production-ready SaaS platforms, AI-powered web applications, healthcare systems, admin dashboards, and backend products using React, Next.js, Node.js, NestJS, Python, and cloud infrastructure. 🏆 Top Rated | 100% Job Success | 120+ Projects | 2,900+ Upwork Hours | 10+ Years Experience Most developers deliver code. I help deliver software that can support real users, internal teams, admins, payments, integrations, and long-term business growth. 𝗪𝗵𝗮𝘁 𝗠𝗮𝗸𝗲𝘀 𝗠𝗲 𝗗𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁 Clients usually hire me when they need someone who can take ownership of the product, not just complete assigned tickets. I think through product architecture, user roles, data structure, API design, scalability, performance, security, user experience, cost optimization, and long-term maintainability before writing code. The goal is not just to launch quickly. The goal is to launch with a system that can keep growing without creating unnecessary technical debt. 𝗣𝗿𝗼𝘃𝗲𝗻 𝗘𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 I have built healthcare and telehealth platforms such as Instant Consult and Instant Touch, covering patient portals, doctor portals, admin dashboards, PMS workflows, appointment scheduling, video consultations, role-based access, AWS infrastructure, reporting, inventory workflows, and secure healthcare operations. For telehealth platforms, I have also worked with custom WebRTC-based video consultation flows, helping reduce dependency on expensive per-minute third-party video providers and making high-volume daily consultations more cost-efficient to operate at scale. I also build practical AI systems for real business workflows, including RAG applications, AI chatbots, document intelligence, knowledge-base chat systems, AI assistants, AI agents, OpenAI/GPT integrations, Claude, Gemini, LangChain, Qdrant, speech-to-text, text-to-speech, and internal AI tools. I have also built admin and business systems that help teams manage users, subscriptions, reporting, content, payments, workflows, and daily operations from one reliable platform.

If you are building a SaaS platform, AI application, healthcare system, dashboard, or custom web product, send me a message with a few details about your project. I’ll review the requirement and suggest the cleanest technical path forward.

Integrated systems rarely break on the first successful API call. They break three weeks later: a failed Shopify webhook, an ERP order that never synced, a CRM contact missing from the pipeline, or POS inventory that no longer matches the store. I build and fix the middleware/API layer behind those systems. My strongest work is around Shopify, ERP, CRM, POS, and Laravel-based backend systems where product data, orders, inventory, customers, payments, and reporting all need to stay aligned. What I usually handle: - Shopify / Shopify Plus integrations and custom commerce workflows - ERP and CRM syncs: Acumatica, Salesforce, Zoho, HubSpot, SAP-style systems - POS and inventory workflows: Clover, store operations, loyalty, order flows - Laravel/PHP middleware, APIs, webhooks, queues, cron jobs, retries, and logs - Admin dashboards, reporting panels, and operational data models - Production debugging where the issue is hidden across multiple systems Relevant background: - Built and supported systems handling 24k+ products, 3M+ users, and 2,000+ locations - Led technical delivery across teams of 20+ - Worked across Shopify, Shopify Plus, Magento, BigCommerce, Acumatica, Salesforce, Zoho, Clover POS, Laravel, REST/GraphQL APIs, PostgreSQL, MySQL, AWS, Firebase, and payment systems I also take on SaaS MVPs and React Native app work when the project depends on backend architecture, integrations, subscriptions, analytics, or production stability. If your store, ERP, CRM, POS, or internal dashboard is held together by fragile syncs and unclear data flow, I can help trace where it breaks and make the system reliable.
