I know how it feels to work on an Automotive or Motorsport project that demands deep analysis, from technical writing and software development, and end up frustrated by generic AI results that lack precision and real engineering depth. With industry experience at leading automotive and motorsport companies, I specialise in turning complex engineering concepts into clear, engaging, and accessible writing! (and software). Whether you need a script for your YouTube channel or a technical article for your website. I focus on precision, clarity, and impactful results. What I Offer: -------------------------------------------------------------- * YouTube scripts for Motorsport and Automotive projects. * Technical documentation for EV, automotive and complex engineering systems. * User manuals for hardware/software platforms. * Proofreading & editing your already-existing documents. Why Work With Me? -------------------------------------------------------------- As an engineer and writer, I know how to speak both “tech” and “human.” I understand how engineers think, and how end users learn. With a strong grasp of systems such as electric powertrains, vehicle dynamics, battery development, and simulation tools (like MATLAB/Simulink or Python), I create scripts that bridge the gap between your target audience and your YouTube channel. Whether you're a YouTube channel owner, a motorsport brand, or an engineering platform looking to clarify your message, I can help you build trust and understanding through professional technical communication. Get in touch; I’d love to hear about your project! Ali

I'm a Full Stack Developer who ships the whole product, the web app, the mobile app, the backend and the integrations, so founders hire one partner instead of coordinating three contractors. 8+ years, 100% Job Success Score across 19 contracts and 2,324 hours on Upwork, Top Rated Plus. Two of those ran past 450 hours each: a $16.7K community platform and a $15.8K fintech build on Plaid and Stripe. One client is now on their fourth contract with me and my team. "Hani is the most capable, brilliant technical partner I have ever worked with. He is not only an expert, but also kind, an excellent communicator, and has generated business ideas..." Client review, $16,765 engagement, 559 hours. WHAT 100% JOB SUCCESS ACTUALLY MEANS Upwork calculates Job Success from how contracts ended, including the private feedback you never see, plus disputes, refunds and repeat hires. Mine is 100% across every contract I have taken. Top Rated Plus is Upwork's highest tier and it is removed the moment performance slips. Neither is bought. The thing you are actually worried about when hiring a stranger, that they go quiet or hand you something you have to argue about, has not happened yet. WHAT I BUILD AS A FULL STACK DEVELOPER SaaS platforms and multi-tenant products. As a SaaS Developer I handle end to end SaaS development, from database schema through role-based access and row-level isolation to Stripe billing and production monitoring. GoodNests is a white-label community SaaS where every organisation gets its own branded web and mobile app off a single codebase, with member analytics and a founder dashboard. JESY is an invite-only B2B marketplace connecting DJs, venues and brands across the global electronic music industry, with in-app negotiation, escrow-secured payments, KYC verification and 360 degree ratings. AI features that survive production. My AI work runs inside shipped products, not demos. ZOVOX, listed on my portfolio as Genesys Financial, is a mobile-first financial platform for self-employed users with Plaid bank sync, Stripe and in-app purchase subscriptions running side by side, and an AI assistant grounded in live transaction data so it never invents a balance. Designed against GLBA and SOC 2 requirements. As an AI integration developer I build with the Claude API and OpenAI, RAG pipelines, embeddings and vector search, streaming chat interfaces with real loading and error states, and per-user token spend caps from day one rather than after the first bill. Next.js and React frontends. I build Next.js dashboards, admin portals and operations consoles in TypeScript, with real-time data and Stripe billing portals. App Router, server components, and component libraries that survive a second developer joining. Node.js backend and APIs. As a Node.js Backend Developer working in Express and NestJS, I design authentication, business logic, background jobs and REST and GraphQL APIs on Postgres, MongoDB, Firestore and Supabase, with integrations across Stripe, Plaid, Twilio, SendGrid, OAuth and mapping providers. Flutter mobile. Cross-platform iOS and Android from one codebase, with push notifications, deep linking, in-app purchases and offline-first patterns. WXW Delivery is three connected apps, customer, driver and operations dashboard, so dispatch, tracking and support live in one stack. I handle App Store and Play Store submission including reviewer pushback, and I have cut load times by 47% on a production release. MY STACK Web: React, Next.js, TypeScript, Tailwind. Backend: Node.js, Express, NestJS, REST, GraphQL. Mobile: Flutter, Dart, Bloc, Riverpod. Databases: Postgres, MongoDB, Firestore, Supabase. Cloud: AWS, GCP, Firebase, Vercel, CI/CD. AI: Claude API, OpenAI, RAG, embeddings, vector search. Integrations: Stripe, Plaid, Twilio, OAuth, Maps. HOW I WORK I think like a product owner and code like a tech lead, so I push back on a spec that will not hold up before we build it rather than after. I flag scope risk early, not at the deadline. Daily updates, predictable timelines, no Friday night surprises. Architecture that scales from the start instead of being retrofitted at Series A. I run a small senior team, a QA lead and full-stack engineers, and I stay through bug bashes, store reviews and v1.1. You talk to me, not a project manager. Message me with your project. Within one business day you will get a real estimate, a suggested approach, and two or three examples from my portfolio that match what you are building, whether you need a Full Stack Developer for long-term product work, a SaaS Developer for a new platform, or a Next.js and Node team to take over an existing codebase. Keywords: Full Stack Developer, SaaS Developer, Next.js Developer, Node.js Backend Developer, React Developer, Flutter Developer, Mobile App Developer, AI Integration, Claude API, OpenAI, RAG, Multi-Tenant SaaS, Stripe, Plaid, Escrow, KYC, Fintech, Marketplace, TypeScript, Supabase, Postgres, AWS, MVP, Startup CTO

What does a Hybrid engineer do?

A hybrid engineer bridges the gap between traditional networking and modern software development by applying DevOps principles to network infrastructure. This role treats network configurations as code, allowing for automated testing and deployment rather than manual device updates. You integrate new technologies with existing systems while maintaining strict security policies and operational stability. The work requires translating technical network changes into business value for stakeholders who need reliable connectivity.

  • Check out current network configurations to verify compatibility before applying any feature or logic changes. You assess how new capabilities interact with legacy systems to prevent outages or security violations during the integration process. This step ensures that every modification aligns with established security policies and operational requirements before it reaches production devices.
  • Apply configuration changes through automated continuous integration and testing pipelines to validate logic and security compliance. You run automated assessment tests to catch errors early, reducing the risk of human mistake in complex network environments. This workflow allows you to push approved changes to network devices with confidence, knowing that each update has passed rigorous validation checks.
  • Deploy tested and validated configurations to production network devices, activating new features or capabilities in live environments. You monitor the activation process to confirm that changes take effect without disrupting existing traffic or services. This deliverable includes documentation of the automation-backed change process, which improves reliability and reduces future deployment errors for the engineering team.

How to hire a Hybrid engineer on Upwork

Step 1: Post a job

Define the intersection of networking and software development your project requires. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description. Describe your needs in a few sentences and Uma drafts a job post for the role. You can write a new post, update a saved draft, or reuse an existing post.

  • Specify requirements for bridging network infrastructure with automated software deployment pipelines.
  • List necessary experience with continuous integration tools that validate network configuration changes.
  • Detail security policy compliance checks needed before pushing updates to production devices.

Step 2: Evaluate candidates

Look for portfolios showing automated network feature deployments and validated configuration scripts. Uma can run instant video interviews and build shortlists with side-by-side comparisons to speed up this review.

  • Verify examples where the candidate tested logic and compatibility before activating changes on live networks.
  • Check for documented workflows that reduce manual errors through automated assessment testing processes.
  • Review case studies demonstrating clear communication of technical network updates to business stakeholders.

Step 3: Interview your top choices

Discuss how candidates balance speed with security when integrating new technologies into existing systems. Interviews can be scheduled and conducted within Upwork Messages with an immediate transcript and summary after each one.

  • Ask how they configure automated pipelines to check security policies before applying network device updates.
  • Request specific examples of troubleshooting failed deployments in a continuous integration environment.
  • Evaluate their method for translating complex network architecture changes into plain business terms.

Step 4: Agree on scope and begin work

Set clear milestones for deploying tested network capabilities and automating configuration checks. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.

  • Define deliverables such as activated network features and validated configuration scripts for specific devices.
  • Establish protocols for running changes through automated testing before pushing to production environments.
  • Agree on reporting formats that track deployment success rates and security compliance validation results.
