I am a Full-Stack Web and Mobile Developer with 8+ years of experience and 11,000+ hours worked on Upwork, helping clients build high-quality web and mobile applications. With strong experience in both frontend and backend development, I can take your idea, Figma design, existing app, or business requirement and turn it into a clean, production-ready product. I work on web apps, mobile apps, dashboards, admin panels, SaaS platforms, API integrations, payment systems, Firebase/Supabase projects, and custom business tools. I also use modern AI development tools like Claude, Cursor, GitHub Copilot, and ChatGPT to move faster, debug smarter, improve code quality, and deliver better results in less time. But I do not blindly depend on AI — every line of code is reviewed, tested, and structured properly before delivery. What I can help you with: - React, Angular, Ionic, and React Native app development - Node.js backend and REST API development - Mobile app development for Android and iOS - Figma to pixel-perfect frontend implementation - Firebase, Supabase, Stripe, Razorpay, and third-party API integrations - Admin dashboards and SaaS platforms - Bug fixing, performance improvement, and code refactoring - AI-assisted development for faster delivery and better productivity I focus on writing clean, maintainable code and building products that are easy to use, easy to scale, and easy to improve in the future. Whether you need a new app from scratch, improvements to an existing project, or a reliable developer to support your team, I can help you deliver high-quality work with speed and clarity.

Mobile apps don't fail because of missing features. They fail because of bad architecture, compliance gaps, and developers who disappear after handoff. 𝐎𝐯𝐞𝐫 𝐭𝐡𝐞 𝐩𝐚𝐬𝐭 𝟖 𝐲𝐞𝐚𝐫𝐬, I've built and shipped 𝟏𝟓+ 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧 𝐚𝐩𝐩𝐬 across Flutter, React Native, Swift, and Kotlin, including a payment SDK deployed to 𝟏𝟎𝟎+ 𝐉𝐏𝐌𝐨𝐫𝐠𝐚𝐧 𝐦𝐞𝐫𝐜𝐡𝐚𝐧𝐭𝐬, a healthcare communication app that grew 𝟑𝟎𝟎% in 𝐀𝐩𝐩 𝐒𝐭𝐨𝐫𝐞 𝐫𝐞𝐯𝐞𝐧𝐮𝐞, a Flutter music player app with 𝟏,𝟎𝟎𝟎,𝟎𝟎𝟎+ 𝐝𝐨𝐰𝐧𝐥𝐨𝐚𝐝𝐬, and an AI-powered sports rule app that added $𝟏𝟒𝟎𝐊+ 𝐢𝐧 𝐀𝐑𝐑 through native paywalls. These weren't projects where I wrote code to spec. Each one required owning technical decisions, navigating App Store policy, designing architecture that could scale, and integrating systems that had no simple documentation - Twilio VOIP, BLE firmware OTA, PCI-DSS payment flows, NDIS compliance workflows, RAG pipelines on top of LLMs. 𝐎𝐧 𝐭𝐡𝐞 𝐀𝐈 𝐬𝐢𝐝𝐞, I've built production 𝐑𝐀𝐆 𝐬𝐲𝐬𝐭𝐞𝐦𝐬 𝐮𝐬𝐢𝐧𝐠 𝐋𝐚𝐧𝐠𝐂𝐡𝐚𝐢𝐧 𝐚𝐧𝐝 𝐏𝐢𝐧𝐞𝐜𝐨𝐧𝐞, 𝐢𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐞𝐝 𝐎𝐩𝐞𝐧𝐀𝐈 𝐀𝐏𝐈𝐬 𝐢𝐧𝐭𝐨 𝐦𝐨𝐛𝐢𝐥𝐞 𝐚𝐩𝐩𝐬 for real-time task detection and natural language search, and shipped an LLM-powered rules engine that became a commercial product.

If you're building something that has to work - App Store approval, compliance requirements, payment flows, AI features, or a migration that can't break production, that's where I do my clearest work.

Python developers, React developers, Node.js developers, AI engineers — all from a pre-vetted pool of top 3% talent. ✔️ PROJECT RESCUE Half-built product? Vibe-coded MVP that needs finishing? App that's live but has performance issues, security vulnerabilities, or can't scale? I take ownership, audit the codebase, and ship. Performance optimization, security hardening, technical debt reduction, production-grade refactoring — all part of what I do. ✔️ HOW I WORK Every engagement runs through a 36-point Quality Standards framework — a proprietary delivery process built over 200+ projects. Accurate estimates. Transparent tracking. On-time delivery. No surprises.

Full-Stack AI Developer — I build AI-powered web & mobile apps, AI agents, and cinematic AI video production with Higgsfield, Veo 3.1, Runway & Kling. 8+ years of deep learning experience turning "is this even possible?" ideas into shipped, revenue-generating products. Most clients need four hires for one AI product: app developer, ML engineer, automation specialist, backend dev. I'm all four — one accountable person from architecture to the launch of the product 🧠 AI AGENTS, LLMs & CHATBOTS Production-grade AI agents and RAG systems that answer from YOUR data — built with GPT-5, Claude, Gemini, Llama 4 & Mistral via LangChain, LlamaIndex & Amazon Bedrock. Voice AI agents (Vapi, Retell, LiveKit, Whisper, Deepgram, ElevenLabs) that handle real customer calls, not just demos. Vector search at scale: Pinecone, Weaviate, FAISS, ChromaDB. 📱 AI-POWERED WEB & MOBILE APP DEVELOPMENT Full-stack SaaS platforms, dashboards & mobile apps with AI at the core — Next.js, React Native, Flutter, Python. Deployed on AWS SageMaker, GCP Vertex AI & Azure with Docker/Kubernetes, optimized with TensorRT so your inference costs don't eat your margins. 🎬 AI VIDEO PRODUCTION & GENERATIVE MEDIA Product ads, UGC-style content, AI avatars & brand films using Higgsfield, Veo 3.1, Runway Gen-4.5, Kling & HeyGen — plus custom ComfyUI pipelines, ElevenLabs voice cloning, lip-sync, and FFmpeg/OpenCV post-production. Output that looks studio-made, not prompt-made. ⚙️ AI AUTOMATION & CUSTOM MODELS Workflow automation connecting LLMs to your CRM, WhatsApp & 100+ tools via n8n, Make & custom APIs. Fine-tuned, industry-specific models (LoRA, DreamBooth, ControlNet) when off-the-shelf isn't enough. WHY ME OVER THE OTHER 10 PROPOSALS → I don't just call APIs — I fine-tune, self-host and optimize models. Where API-wrapper freelancers hit a wall is where I start. → Your product and its marketing content share one brain, one vision. → Working demo or sample clip BEFORE you commit to the full build. Not sure if your idea is technically possible — or what it would cost? Send me ONE line describing it. Within 12 hours you'll get 2–3 concrete build approaches and an honest feasibility check. Free, no strings. 📩 Hit Invite or message me now — let's ship the product AND the content that sells it.
