That combination of hands-on development and team leadership means I can either jump in and build your app myself or bring in my team for larger projects that need to move fast.
Ranked in the Top 10% on Upwork. Here's what I actually do:
Mobile App Development
- Cross-platform apps with Flutter and Dart — single codebase, native performance on iOS and Android
- Native iOS development in Swift and Objective-C (Xcode, SwiftUI, UIKit)
- Native Android development in Kotlin and Java (Android Studio, Jetpack Compose)
- iPad and tablet-optimized layouts for larger screen experiences
- Full lifecycle: architecture, prototyping, development, testing, App Store and Google Play deployment
Web Development
- Responsive web applications and progressive web apps (PWA)
- Front-end development with modern frameworks — React, Next.js, HTML5, CSS3, JavaScript, TypeScript
- Back-end development with FastAPI, Node.js, Django, and serverless cloud functions
- Admin dashboards, landing pages, SaaS platforms, and e-commerce websites
- UI/UX design collaboration using Figma & Stitch design with AI— wireframes, prototypes, and design handoff
AI Integration and Intelligent Features
- LLM integration using OpenAI API (GPT-4, GPT-5), Google Gemini API, and Claude API
- Custom AI chatbots and conversational AI assistants for mobile and web apps
- RAG (Retrieval-Augmented Generation) systems that answer questions from your own business data
- AI-powered features — smart recommendations, voice assistants, image recognition, predictive analytics
- Model fine-tuning for domain-specific tasks using OpenAI, Hugging Face, and custom datasets
- Machine learning pipelines with TensorFlow, PyTorch, and scikit-learn
- AI agent development — bots that reason, plan, and take actions across your business tools
- Prompt engineering and LLM optimization for production-grade accuracy
What ties all of this together is that I don't just plug in an API and call it a day. I build AI features that actually solve a business problem — whether that's reducing support tickets with a smart chatbot, personalizing a user feed with ML, or automating a workflow that used to take your team hours.
Backend and Infrastructure
- Firebase (Firestore, Auth, Cloud Functions, Storage, FCM push notifications)
- Databases: PostgreSQL, MongoDB, MySQL, real-time databases
- RESTful API design and third-party API integration
- Payment gateways: Stripe, PayPal, Worldpay, Apple Pay, Google Pay
- Cloud: AWS, Google Cloud Platform, Microsoft Azure
- CI/CD pipelines, GitHub Actions, automated testing
Industries I've delivered production apps in:
Healthcare and telemedicine, fintech and digital wallets, e-commerce and marketplaces, food and grocery delivery, ride-hailing and logistics, real estate, fitness and wellness, on-demand home services, SaaS platforms, social networking, video streaming, and education.
How I work:
I follow Agile methodologies — Scrum sprints or Kanban, depending on what fits your project. I use Jira, Trello, Asana, or Slack for project management and communication. Git and GitHub for version control. Clean architecture with MVVM and GetX patterns. I write code that the next developer can actually read.
I've managed client projects ranging from quick MVP builds for seed-stage startups to long-running products for established businesses processing thousands of daily users. I'm comfortable owning the full technical scope or collaborating alongside your existing team.
Not the cheapest option, but I show up every day, communicate clearly, and ship on time. If something goes wrong, I'll tell you before it becomes a problem.
Drop me a message with a quick summary of your project. Happy to jump on a 15-minute call to talk through the scope, timeline, and whether we're a good fit.
