I'm Syed Ali Raza, an Android-first mobile developer with 5+ years of experience building production-grade apps for startups, businesses, and global enterprises. My core strength is native Android development with Kotlin and Jetpack Compose — clean architecture, smooth performance, and code that scales. I also build cross-platform with Flutter when the project calls for it. What sets my work apart today is AI integration — I connect mobile apps with OpenAI, Claude, and Gemini APIs to deliver intelligent, modern user experiences that go beyond standard functionality. What I built: Native Android apps — Kotlin, Jetpack Compose, MVVM, Clean Architecture Cross-platform apps — Flutter & Dart AI-powered features — OpenAI, Claude, Gemini API integration Payment systems — Stripe & PayPal Realtime & backend — Firebase, REST APIs MVPs, SaaS tools, on-demand apps, e-commerce, social platforms I've delivered apps for global clients including Hochiki, Midas Safety, and Adseal — across safety compliance, retail operations, and on-demand services. Every solution was built around the client's actual business problem, not just a feature list. I communicate clearly, deliver on time, and stay available after launch. If you need a reliable mobile developer who understands both clean code and modern AI, let's talk.

Java Spring Boot full stack developer specializing in fintech platforms and payment systems - Stripe, Plaid, and custom payment gateway integrations for enterprise and growing startups. I build secure, scalable backend systems that handle real money: wire transfers, EFT payments, subscription billing, and bank integrations. My work sits at the intersection of clean Java architecture and financial compliance: Spring Security, ISO 20022, PCI-aware design, and AWS serverless infrastructure. My core focus is payment gateway integrations: Stripe integration, Plaid integration, Interac, and custom EFT/Wire flows built on Spring Boot microservices designed for high-volume transaction processing. I also deliver full fintech SaaS platforms from MVP to production-ready architecture, AWS serverless infrastructure using Lambda, Fargate, SQS/SNS and Aurora PostgreSQL, and React frontends connected to financial backends. How I work: I start with a technical audit or business analysis to map exact requirements before writing a line of code. Every integration is documented, tested with JUnit, and handed over with internal team training so you can maintain and extend it in-house. Recent work: Delivered a full Interac payment integration for a UK-based fintech expanding into Canada, launched in 20 days using Java microservices and ISO 20022 standards with zero post-launch issues. Separately scaled a B2B payment SaaS platform to handle 10x transaction volume using AWS serverless architecture, cutting infrastructure costs by 30%. If you're building a fintech platform, integrating a payment gateway, or need a reliable Java backend partner for the long term, let's talk.
