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: โœ“ Laravel SaaS backends - multi-tenant architecture, billing integrations (Stripe, PayPal), job queues, real-time features with Reverb or Pusher โœ“ RESTful and headless API development - versioning, authentication (Sanctum, Passport, JWT), third-party integrations, and passive contract monitoring so integrations don't silently break โœ“ WordPress - custom plugins, hook architecture, WooCommerce extensions, REST API bridges between WP and Laravel systems โœ“ 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 โœ“ 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

I build data- and API-heavy platforms on Laravel + React โ€” and own them end-to-end. My focus is the parts most developers bolt on as an afterthought: interactive maps (Mapbox / Leaflet / Google Maps) and Meta / Google marketing-API integrations. 15 years, 50+ projects delivered, 100% Job Success. I work best on systems built to last and grow โ€” but I'm just as happy taking a single, well-scoped task to start. โš™๏ธ FULL-STACK WEB PRODUCTS Laravel APIs paired with React frontends, built to last โ€” not just to ship. From SaaS platforms and admin dashboards to a multi-brand CMS engine powering 15+ automotive dealer websites (Volvo, Mercedes-Benz, Alfa Romeo, Jaguar, Land Rover). ๐Ÿ—บ Interactive Maps โ€” Mapbox / Leaflet / Google Maps API โ—พ Custom maps: styled tiles, markers, plotting live data โ—พ Map tools: drawing & editing shapes, measurements and calculations on the map โ—พ Example: a solar-PV design tool with live roof mapping ๐Ÿ› ๏ธ Meta Graph / Marketing API โ—พ Lead capture: real-time leads delivered straight to CRM, email, or messenger โ—พ Ad tooling: custom reporting logic, automated insights, campaign automation โ—พ Publishing & analytics: posting to Instagram/Facebook (feed, stories), post & profile insights ๐Ÿ—ƒ๏ธ Google API โ—พ Custom Looker Studio connectors โ—พ Google Merchant Center feeds (recent project: 30k+ SKUs synced) โ—พ Google Ads automation tools ๐Ÿ’ณ Payments โ—พ Standard and custom Stripe / PayPal / Afterpay integrations However you want to start โ€” a full build, a senior pair of hands on an existing codebase, or one focused task (a map feature, a Meta/Google API integration, a tracking or feed setup) โ€” I'm easy to work with and quick to get going. Send a short note about your project, even a rough idea, and I'll tell you honestly how I'd approach it. ๐Ÿค Thank you, Vitalii Komliev

API developer hiring guide

API developers design and build the connections that power modern software ecosystems. From enabling real-time data exchange between platforms to creating secure endpoints for mobile apps, these professionals help businesses automate workflows, improve system integration, and unlock new product capabilities.

What does an API developer do?

An API developer builds and maintains application programming interfaces (APIs) that allow software systems to connect, share data, and perform tasks. These professionals focus on designing secure, well-documented, and scalable APIs that enable seamless integration between platforms, mobile apps, and web services.

Companies hire API developers to streamline operations, connect external providers, automate internal workflows, and enable third-party access to their software products.

How to hire an API developer on Upwork

Hiring the right API developer starts with a clear job post and continues through evaluating skills, communication, and compatibility.

Step 1: Craft a targeted job post

A well-crafted job post attracts qualified API developers who match your project requirements.

  • Share your objectives. Start with a clear job description that outlines your technical needs and goals.

  • Define your tech stack. Mention if your system uses RESTful APIs, GraphQL, AWS, or specific frameworks like Flask or Express.

  • List use cases and deliverables. Explain what the API should do and include whether you need documentation, testing, or integration support.

To streamline this step, use the Job Post Generator, powered by Umaโ„ข, Upworkโ€™s Mindful AI, to quickly draft a customized job post for your review.

Step 2: Filter and evaluate candidates

Systematically assess candidates based on technical expertise, project history, and tool proficiency.

  • Search the talent pool using Upwork's filters for skills, hourly rate, and work history.

  • Review portfolios. Look for experience building secure APIs with scalable architecture.

  • Check API design experience. Strong developers demonstrate knowledge in API management, life cycle, and versioning.

  • Look for relevant tools. Confirm familiarity with Postman, Swagger/OpenAPI, AWS, and authentication systems like OAuth.

You can use Upworkโ€™s instant video interviews to screen applicants for a best-fit shortlist, with Uma providing side-by-side candidate comparisons.

Step 3: Interview your top choices

Direct conversations reveal how candidates approach technical challenges. Consider these common back-end developer interview questions to structure your discussions.

  • Discuss their process. Ask how they design, test, and deploy APIs and handle edge cases.

  • Explore documentation standards. Clear API documentation improves developer experience and long-term usability.

  • Ask about scalability. Confirm the developer understands how to optimize APIs for performance.

Upwork Messages allows you to schedule and conduct live video interviews on the platform, with call transcripts and summaries available after the calls.

Step 4: Agree on scope and begin work

Before starting the work, youโ€™ll want a firm contract in place Establishing well-defined project parameters before work begins creates a foundation for successful collaboration.

  • Define project structure. Choose between a fixed-price or hourly contract based on your project scope.

  • Outline deliverables and timelines. Break work into sprints or milestones where possible.

  • Discuss access and security. Ensure safe sharing of API keys, credentials, and runtime environments.

  • Plan for maintenance. Set terms for ongoing support if needed.
