I am a software engineer with 14 years of software development experience. I am experienced in web and cross-platform OS development using JavaScript, TypeScript, Rust, Python, C#, Kotlin, Java, Swift, Go, and AWS services. I have been working in enterprise software for Fortune 400, gas and oil conglomerates, and tiny startups. I have also designed and developed systems that are running under load using combinations of different runtimes and environments. Starting from Tauri and finishing GraalVM. When working on a new project, my main priority is to make sure that your needs are met and the problems are solved. Thank you in advance for your time and consideration. I look forward to working with you soon.

I help startups and growing businesses build fast, scalable web and mobile apps using Python, Laravel, React Native, and React. I work as a full stack developer who can take a product from idea to production with clean code and predictable delivery. If you need a reliable web developer for modern UI work and a strong mobile app developer for iOS/Android builds, I can cover both while staying hands-on as a full stack developer focused on performance, UX, and maintainability. I’ve delivered solutions for founders who need speed now and stability later, and I communicate clearly at every step.🔥 I’m an experienced Web engineer, React engineer, Vue engineer, and React Native engineer with 7 years of production experience. As a full stack developer I can build backend APIs, admin panels, dashboards, and customer-facing apps, and as a web developer I pay attention to UI details that improve conversion and retention. I’ve completed a wide range of successful projects, from MVPs to large systems with long-term maintenance and continuous improvements. 🚀I also lead a web development team, techXen Solutions . We have multiple Laravel developers (Senior PHP and Custom PHP MySQL), Python (Django), and JavaScript (React, Vue, React Native) developers. If your project needs a dedicated mobile app developer, we can staff that role quickly, while I stay involved as a full stack developer to keep architecture, delivery, and communication aligned. When the UI scope grows, a senior web developer can join the project while I remain the full stack developer responsible for end-to-end quality.🚀 Our team has already worked in such industries as: ✅ Marketplace ✅ E-commerce ✅ Travel and Hospitality ✅ Custom ERP (Enterprise Resource Planning) ✅ ChatGPT integration (LLM model in your website front end) ✅ Automotive (car inspection, automotive ERP, car sharing, rental, selling) ✅ Social media (Tinder-like networks, short video platforms, communities) ✅ Sales (CRM systems for sales teams, retail, hospitals, sales departments) ✅ Sport (gym management systems, trainer platforms, fitness apps, club portals) ✅ Legal (document automation, AI-assisted legal processing) ✅ Healthcare (clinic management, booking, mental health software) ✅ Education (LMS, automated training, coaching marketplaces) ✅ Finance (fintech platforms, investment platforms, bank API integrations, calculators) ✅ Manufacturing (shop floor management and automation) ✅ Human resources (HRM systems) ✅ Digital marketing (Meta, Facebook/Instagram, TikTok, Google APIs, analytics) Stack of technologies we use: ✅ HTML/CSS, Bootstrap, Tailwind ✅ JavaScript (React, Vue, Node.js, Express, AdonisJS, Nuxt) ✅ React Native for cross-platform mobile delivery ✅ API integrations (Stripe, PayPal, Twilio, TextMagic, Xero, DocuSign, Google Maps, Meta APIs, and more) ✅ API development (Laravel, Node/Express, Firebase, Python/Django, Go, REST, GraphQL) ✅ PWA (Progressive Web App) ✅ Databases: MySQL, PostgreSQL, MongoDB, DynamoDB, Elasticsearch ✅ Infrastructure: AWS, DigitalOcean, Firebase, Supabase ✅ DevOps and administration: LAMP, CentOS, Ubuntu As a full stack developer, I connect the front end, back end, and infrastructure so releases are smooth. When the scope includes native-like UX, I can collaborate with a mobile app developer without slowing down the API roadmap, and a web developer can refine UI flows while we keep the backend stable. You can hire me as a full stack developer for full ownership, or extend the team and keep me as the full stack developer leading architecture and delivery. If timelines are tight, add a mobile app developer to parallelize mobile features, and add a web developer to accelerate dashboards and front-end work. 🚀 Buzz words clients search for: website development, JavaScript, React MySQL, Amazon Web Services, API integration, database architecture, CRM, custom ERP, REST, GraphQL, Laravel, React, Vue, React Native. If you need a full stack developer who can also guide a delivery team, I’ve done that for years. If you need a reliable mobile app developer for consistent releases and store readiness, we can support that too, and if you need a web developer for pixel-perfect UI, that’s covered. In our work history you’ll find successful products built with React, JavaScript, MySQL, React, Vue, and React Native, plus multiple systems built with Python (Django, Flask, FastAPI). I also use LLM capabilities and AI APIs (including OpenAI integrations) when they genuinely improve the product experience. We have 15 senior developers across React, JavaScript, MySQL, Python, Go, and Node.js. As a full stack developer, I can jump into an existing codebase, stabilize releases, fix bottlenecks, and plan the next iterations. Please contact me for further details and fruitful work. Best regards, Asmar Naeem CEO, TechXen Solutions

Communication was excellent throughout the collaboration, with daily updates and consistent progress reflected in GitHub. He was incredibly professional, reliable, and remained on the project for several months, which was a highlight for us after past challenges with other agencies. We highly recommend Anton and look forward to working with him again. Thank you for the fantastic collaboration! ❞ 🗣 𝙆𝙚𝙫𝙞𝙣 𝙆𝙪𝙝𝙣 - 𝘾𝙀𝙊 - 𝙂𝙤𝙥𝙛 (𝘼𝙜𝙚𝙣𝙩𝙞𝙘 𝘼𝙄 𝙎𝙤𝙡𝙪𝙩𝙞𝙤𝙣𝙨) 🗣 ⭐⭐⭐⭐⭐
