🥇 Top Rated Plus | 41+ Jobs Completed | 3,200+ Hours | 100% Job Success I'm Syed Umair, a senior mobile app developer with 9+ years of experience building and hardening production apps in Flutter and React Native. Clients come to me for two things: building solid mobile apps from scratch, and honestly telling them what's broken, unfinished, or risky in apps they already have. I don't sugarcoat audits, if something isn't production-ready, I'll say so clearly and back it up with evidence. WHAT I DO: 📱 Mobile App Development Custom Flutter & React Native apps for iOS and Android, from idea to App Store launch. Clean architecture, maintainable code, real production readiness (not just "it works on my machine"). 🔍 Code & Production-Readiness Audits I review existing Flutter/React Native + Laravel/Node/Firebase codebases and give you a clear, prioritized verdict: what's a launch blocker, what's safe for beta, what's just technical debt. Non-technical founders especially value this, I explain everything in plain language. 🔗 Backend & Integrations Laravel, Node.js, and Firebase backends. Stripe payment integration (subscriptions, auto-charges, webhooks, refund/failure handling), Google Maps/Navigation SDKs, real-time features (WebSockets/Firebase). 🚀 App Store & Launch Support In-app purchase setup, App Store/Play Store submission, and post-launch troubleshooting. WHY CLIENTS WORK WITH ME: ✔ Direct, honest technical judgment, I tell you what's actually true, not what's easiest to hear ✔ Clear communication tailored for both technical and non-technical founders ✔ Strong track record auditing and hardening apps others built ✔ Full-cycle: architecture review → development → integration → launch TOOLS & TECH: Frontend: Flutter, React Native, Kotlin (native Android) Backend: Laravel, Node.js, Firebase Payments: Stripe (webhooks, subscriptions, auto-billing) Other: Google Maps/Navigation SDK, TestFlight, App Store/Play Store submission Have an app that needs to get built right, or an existing app you're not sure is really production-ready? Send me a message or click "Hire Me" and let's talk.

Java sits at the center of the platforms I build. Spring Boot runs the backend services and APIs, handling business logic, data access, and the core behavior of the system. Many of these platforms pair a Spring Boot backend with Angular on the frontend, forming structured web applications such as internal dashboards, operational platforms, and SaaS systems used by teams every day. Angular provides the application interface while the Java backend manages services, data, and integrations behind the scenes. Python also comes into play when automation or data workflows are needed. Small services and scripts written in Python handle background tasks, integrations, and operational processes that support the main platform. Java and Spring Boot handle the backend services, Angular runs the platform interface, and Python supports automation and background tasks.

$700K+ delivered on Upwork across 145 projects with a 100% Job Success Score. I architect and ship production AI systems, Voice AI agents handling live calls under 2-second latency, computer vision platforms processing 8M+ daily events, and full-stack products running in production for years. What I build: 𝗩𝗼𝗶𝗰𝗲 𝗔𝗜 & 𝗖𝗼𝗻𝘃𝗲𝗿𝘀𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗔𝗴𝗲𝗻𝘁𝘀 Real-time voice pipelines combining speech-to-text, LLM reasoning, and natural voice synthesis. I built SloanConnect, an AI telephony platform that automates insurance verification calls end-to-end, navigates IVR systems, holds dynamic conversations with representatives, and scales to hundreds of concurrent calls. Sub-2-second response time, encrypted compliance handling, production-stable. 𝗖𝗼𝗺𝗽𝘂𝘁𝗲𝗿 𝗩𝗶𝘀𝗶𝗼𝗻 𝗮𝘁 𝗦𝗰𝗮𝗹𝗲 Lead AI Engineer on two production CV platforms: Adlytic - privacy-safe in-store retail analytics with GDPR-compliant pipelines, heatmaps, and POS integration, and SportsEye - real-time soccer analytics from broadcast feeds with 96% accuracy across player tracking, field mapping, and tactical metrics with zero on-field hardware. 𝗠𝗮𝗰𝗵𝗶𝗻𝗲 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 Hybrid recommendation engines on PySpark processing 8M+ daily impressions. NLP and sentiment systems wired into live dashboards. Healthcare process automation with HIPAA-aligned data handling. Models built to live in real environments, not notebooks. 𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗟𝗟𝗠 𝗪𝗼𝗿𝗸𝗳𝗹𝗼𝘄𝘀 (𝗖𝗹𝗮𝘂𝗱𝗲, 𝗢𝗽𝗲𝗻𝗔𝗜, 𝗺𝘂𝗹𝘁𝗶-𝗺𝗼𝗱𝗲𝗹) End-to-end AI agents shipped to production: a Shopify + Amazon SP-API customer service agent with order lookup, refunds, returnless-refund policies, Slack/Email approval gates, and Klaviyo sync. Multi-step LLM pipelines with tool use, RAG, function calling, and human-in-the-loop checkpoints. I design these as systems, not single prompts, and I'm comfortable across Claude, OpenAI, and open-weight models depending on what fits the workload. 𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 𝗙𝗼𝘂𝗻𝗱𝗮𝘁𝗶𝗼𝗻𝘀 Every AI product needs scaffolding that holds. I've shipped Django/Node/React/Next.js platforms that ran 3+ years in production, Alchemist Real Estate, audIT.app, and a long-running B2B SaaS that grew from MVP to hundreds of users across $195K+ in contracted development. Distributed backends, REST/GraphQL APIs, AWS-native deployment, data pipelines, and the DevOps to keep them stable. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 As Lead Engineering Architect, I stay hands-on through the whole lifecycle, discovery, architecture, core implementation, deployment, and the long tail. I don't hand off and disappear. Most of my Upwork work is repeat business or long contracts measured in years, not weeks. If you're building a Voice AI agent, a computer vision platform, an LLM-driven workflow, or a full-stack AI product that needs to survive real load - let's talk.
