You will get a lightweight Google Chrome Extension + API Integration

Project details
I build production-ready Google Chrome extensions designed for real users and real workflows, not demos or experiments.
This project is ideal for teams that need a secure, maintainable Chrome extension, either as a standalone tool or tightly integrated with an existing SaaS. I’ve worked on extensions that reduce context switching by bringing key product functionality directly into the browser.
My approach is engineering-driven and product-focused. I pay close attention to extension architecture (popup, background, content scripts), permission scoping, state management, and performance—especially under Chrome’s Manifest V3 constraints. API integrations are handled securely, with clear authentication flows and error handling.
If your extension connects to a SaaS, I can align it with backend logic such as user roles, usage limits, or credit-based systems. You’ll get clean implementation, clear technical decisions, and an extension built to scale.

ReactJs (Sea project)
I hired Sultan to build our React.js front end on a tight deadline, and he delivered on schedule with pixel-perfect, responsive layouts.
His code is clean, modular, and easy to maintain, and optimized for faster load times.
Communication was outstanding, rapid responses, and thoughtful UI/UX suggestions.
Sultan met every request, treated our project as his own, and consistently demonstrated professionalism.
I highly recommend Sultan for any front-end development needs and I will be hiring him to complete M2 of the project and many other future projects.
Keep up the good work !!!

Hello!
I am a front-end focused Fullstack Developer, been in this industry since 2019 as pure-frontend skills. I am evolving with broader skills and got some exposure into backend tools and software, making me able to work as Fullstack. I've built software with wide-range cross-domain specialty; Travel Agent, Logistics and Shipping, SaaS, and now here I am in Hospitality Industry.
I am recognized as a product-minded Software Engineer with a strong passion for crafting digital products and solving everyday problems. My product sense was shaped during my time at a travel agent startup, where I had to deeply understand the business, users, and operations behind the product, not just the code.
Now, I am building 3 my own SaaS:
- FreelancerrFlow
- SPED goals iOS app
- motocare: Vehicle Maintenance app.
>>> Those SaaS builts on top of my own problem, trying to solve it by myself.
What I've delivered:
→ 50% faster builds on AWS Codebuild by fixing memory failures crippling deployments at Archipelago International (200+ hotels, 45,000+ rooms). 16 min → 8 min. This reduced the ops team waiting time.
→ 2.2× more shipped work. I replaced an unguarded release process with gated CI across 8 production repos. Reviewed PRs jumped 44 to 96, at a 100% pre-merge pass rate.
→ A new revenue channel from zero, I built a complete wedding inquiry platform across 4 hotel brands. Live API data, WhatsApp flow, SEO schema. Brands that couldn't capture wedding leads online now can.
→ An AI financing OS, built from scratch. I build FreelancerrFlow: full product, AI at the core, database to deployment.
→ Logistics that runs in production. I worked on OMS, WMS, and freight-forwarding features at Shifl, used in real supply chain operations.
I integrate Claude and OpenAI APIs with rate limiting and cost controls built in from day one, ship custom AI agents, and automate manual work with n8n.
This isn't portfolio work. It's in production right now.
Hire me for:
1. AI features that ship into your live product (search, chatbots, extraction, generation).
2. Hospitality & booking platforms I've already built at scale
3. Logistics tooling. I built this tooling during my time at Shifl.
4. CI/CD pipeline that makes your whole engineering team faster
5. Full SaaS, owned end to end
Stack: Vue 3 · Nuxt · React · Next.js · TypeScript · Node.js · Laravel · PostgreSQL · Supabase · Firebase · React Native · Claude API · OpenAI · n8n · Docker · Playwright · AWS CodeBuild
Send me the problem. I'll own the outcome.
