Top Rated Plus · 14 years building high-performance mobile and web products.
I'm a senior full-stack engineer specializing in React Native, React.js, Next.js, Node.js, NestJS, and Python — with a strong and growing focus on AI/ML integration. I also build cross-platform mobile apps with Flutter when the project calls for it. I help startups and product teams turn complex ideas into production-ready apps that scale.
→ React Native apps — Expo & bare workflow, TypeScript, New Architecture, offline-first, biometric auth, in-app purchases, real-time sync, and native module integration
→ Flutter apps — cross-platform mobile with clean architecture, BLoC/Riverpod state management, and FlutterFlow for rapid prototyping
→ React.js & Next.js web apps — SSR/SSG, App Router, performance optimization, and complex state management (Redux, Zustand, React Query)
→ Node.js & NestJS backends — REST & GraphQL APIs, microservices, WebSockets, event-driven architectures, and scalable modular monorepos
→ Python — Django, FastAPI, and Flask for backend services; scripting, automation, and data pipelines
→ AI/ML integration — LLM-powered chatbots and AI agents, RAG pipelines, recommendation systems, NLP, computer vision, and predictive analytics
→ Cloud & DevOps — AWS (Lambda, EC2, S3, RDS, Amplify), CI/CD pipelines, Docker, and Kubernetes
How I work-
I write clean, well-documented code and take architecture decisions as seriously as feature delivery. Whether you need a solo developer who can own a product end-to-end, a tech lead for your team, or someone to integrate AI into an existing product — I'll keep communication tight and timelines honest.
I've partnered with clients across the USA, Canada, the UK, Europe, the Middle East, Asia, Australia, New Zealand, Latin America, and Africa — from early-stage startups to established enterprises. I understand how different markets operate, how distributed teams collaborate, and what it genuinely takes to ship products that users love and businesses grow on.
If you're building something ambitious — let's talk.

I’m a Full Stack Developer, SaaS Developer and Backend Developer focused on building production-ready software that holds up under real-world usage. My work sits at the intersection of software developer, web developer, and SaaS platform builder, with a strong backend-first mindset and deep attention to scalability, performance, and long-term maintainability.
As a Full Stack Developer, I take ownership of systems end-to-end, pairing robust backend architecture with clean, modern interfaces. My frontend work is typically React-based and I often collaborate with or replace traditional React developer or web developer setups by owning both frontend and backend in a single, coherent system. While I’ve previously worked as a WordPress developer and integrated WordPress-based sites into custom platforms, my current focus is on custom SaaS and API-driven systems rather than CMS-centric builds.
As a SaaS Developer, I help companies design, build and scale SaaS products, internal tools and API-driven web applications intended for long-term use. My experience as both a Backend Developer and software developer allows me to think beyond features and focus on architecture, reliability and operational stability from day one. Many of the platforms I build support internal teams, customer dashboards and multi-role workflows where permissions, data integrity and business rules are critical.
In my day-to-day work as a Backend Developer, I design and implement backend services, APIs and data models that power SaaS platforms, complex web applications and mobile-connected systems. I regularly work with Node.js and Python, drawing on my background as a Python developer to build scalable services, background jobs and asynchronous workflows that perform reliably in production.
As a Full Stack Developer, I ensure these backend systems integrate cleanly with frontend applications, mobile extensions and third-party APIs. When required, I support frontend and mobile app developer workflows using React and React Native. This end-to-end ownership is a key reason clients bring me in as a Full Stack Developer rather than splitting work across multiple roles.
A significant portion of my work as a SaaS Developer and Backend Developer involves building internal platforms, dashboards and API-first systems that integrate external services. In these projects, I often collaborate closely with product, growth, or analytics teams, including teams focused on SaaS marketing by designing clean data pipelines, event tracking and backend logic that supports experimentation, reporting and lifecycle insights.
When projects require AI-powered functionality, I bring hands-on experience integrating AI into backend systems. While my primary role remains Full Stack Developer and Backend Developer, I regularly implement AI-enabled workflows, data processing pipelines and LLM-driven features inside SaaS platforms. This allows me, as a SaaS Developer, to deliver AI functionality that is reliable, observable and cost-controlled rather than experimental.
Clients typically work with me when they need:
- a Full Stack Developer who can own frontend and backend
- a SaaS Developer who understands long-term scalability constraints
- a Backend Developer experienced with real production systems
- mobile app developer and React developer experience as a software developer
- backend services built with Node.js or Python by an experienced Python developer
- web applications with complex workflows and business rules from a senior web developer
- API-driven architectures and third-party integrations
- SaaS platforms designed to support growth, analytics and SaaS marketing data needs
- MVPs that can realistically evolve into long-term SaaS products
A large part of my work as a Full Stack Developer, SaaS Developer and Backend Developer focuses on:
- multi-role dashboards and internal tools
- authentication, authorization and permissions
- API-first backend system design
- integrations with external platforms, including legacy CMS or WordPress-based systems when required
My core work as a Backend Developer and Full Stack Developer covers:
- backend services built with Node.js and Python
- APIs, background jobs and integrations
- databases such as PostgreSQL
- modern stacks using tools like Supabase
- AI-enabled backend features where they add real business value
I regularly work on MVP builds and early-stage products as a SaaS Developer, with strong focus on solid backend foundations, sensible scaling paths and avoiding short-lived prototypes. Based on scope and timing, I work hands-on as a Full Stack Developer, SaaS Developer and Backend Developer and when useful, involve specialists from my team.
Long-term results come from clarity and intentional system design. I focus on delivering software that teams can confidently run, maintain and scale.
