🚀 Top Rated Plus Full-Stack Developer helping startups and SaaS companies build fast, scalable web apps that actually ship, from idea to production.
Senior Full-Stack Developer with 8+ years in Laravel, Node.js, Vue.js, Nuxt.js, React, and Next.js. I specialize in SaaS platforms, booking systems, CRMs, and high-scale web applications. From marketing sites to complex CRMs, dashboards, and multi-tenant platforms, I build the full stack end to end. You get clean code, measurable performance, and a developer who takes full ownership.
⭐ 100% Job Success Score across 19 projects and 2,100+ hours on Upwork.
✅ Proven results:
📈 Scaled an enterprise SaaS from 200 to 5,000+ users with zero downtime, using multi-tenant architecture, RBAC, and real-time collaboration.
🏢 Built a multi-tenant platform and role-based CRMs handling leads, routing, and compliance for real estate and lead-gen businesses.
💳 Shipped a complete booking platform in 5 weeks with Stripe, PayPal, and Klarna plus Google Calendar sync. It now processes 500+ bookings/month.
🚀 Cut page load times by 65% for a multilingual real estate platform (10,000+ monthly visitors) via PageSpeed audits, refactoring, Redis caching, and CDN.
⚡ Built APIs handling 50,000+ daily requests with auto-scaling and distributed caching, improving response times by 20%.
🔍 Boosted organic traffic by 60% on a chauffeur booking site through mobile-first architecture and SEO.
🧩 Problems I solve:
App is slow → end-to-end optimization (lazy loading, caching, CDN, query tuning)
Payments failing → reliable Stripe, PayPal, and Klarna flows
Systems don't talk → clean REST and GraphQL APIs
Codebase is messy → refactor into scalable, documented architecture
Need to scale → multi-tenant, fault-tolerant systems with auth, RBAC, encryption
Design isn't pixel-perfect → Figma to responsive, accessible code
⚙️ Core stack:
Frontend: Vue.js, Nuxt.js, React, Next.js, TypeScript, Tailwind CSS
Backend: Laravel, Node.js, Express.js, Python (Django, FastAPI)
Databases: MySQL, PostgreSQL, Redis
Integrations: Stripe, PayPal, Klarna, Twilio, OpenAI / ChatGPT
Cloud: AWS, Docker
🚀 How I work: phase-based delivery, live previews, transparent communication, and post-launch support. Every build is performance-tested and security-hardened.
✨ Ready to build? Send me your project details and you'll get a clear, actionable execution plan within 24 hours.

⭐ Some of our notable Projects in a nut shell
🔹 Life Smarter – Consumer Home Security Edge Gateway
We developed a highly customized security solution for consumer home security, enabling real-time intrusion, fire, theft, and burglary detection with automated police dispatch. The system is built on the Dusun 210-F Edge Gateway with Rockchip RK3328, integrating LoRa, Zigbee, Z-Wave, BLE, WiFi, LTE, and Hardware Security Modules (HSM) for encrypted communications. The firmware supports Secure Boot, AVB, DM-V, Rootfs encryption, and A/B firmware updates via Mender to ensure a highly secure and reliable system.
🔹 Custody Protect – IoT Smart Handcuff
We recently developed an IoT Smart Handcuff used for monitoring prisoners in custody in the USA. Custody Protect helps police and prison monitoring officers track each prisoner’s health status and detect violations of predefined conditions. Our team developed the entire end-to-end stack – backend, user apps, firmware, and PCB design. The ESP32 interfaces with multiple components like RFID, LoRaWAN, BLE, WiFi-BLE Mesh Network, and UWB to securely transmit data to the cloud.
🔹 Device Thread – OpenWRT & Intel NUC-Based Edge Server
We built an Edge Gateway solution where OpenWRT powers a captive portal for user activity logging and intelligent bandwidth management, including IP-based controls. An Intel NUC running Ubuntu functions as a robust OTA server for seamless updates and hosts a local server for secure Smart TV management and Automated Device Binding (ADB) operations. This setup ensures efficient, secure, and scalable network management for enterprise deployments.

I build AI automation and integrations for startups and growing businesses. Voice agents, AI-powered workflows, and API integrations that actually run in production, backed by a full-stack engineering base when a project needs the whole thing built, not just wired together.
Most of my work now connects AI into real products. Retell voice agents, OpenAI and Claude API integrations, RAG systems, and end-to-end automation with Make and n8n. I built the automation behind Tranflo, an AI voice agent for restaurants that ties Retell, OpenAI, Twilio and POS systems together, so this is shipped work, not theory.
When a build needs a backend, dashboard, or full app around the automation, I cover that too. PHP/Laravel and Node/MERN, Vue and Angular on the front end, MySQL and MongoDB, Firebase and Supabase, Stripe and PayPal. Custom dashboards, multi-vendor eCommerce, and Chrome extensions when the job calls for it.
I'm comfortable joining an existing team or working with other freelancers, I'm flexible on hours, and I write code meant to run in production. If you want someone who understands the business side as well as the build, message me and tell me what you're working on.
