Hire the Best Android Developers in Jaipur, IN

AWS Certified Solutions Architect with 9+ years building high-traffic cloud systems - now I build AI systems that run entire workflows end to end, not chatbots. Done properly that is a 5x change in what a team can get through, not a 5% one. ** See my portfolio below for working examples with architecture diagrams. ** MY SERVICES 1. Custom AI Agent Development - Multi-agent systems that plan, use tools, call your internal APIs and carry a task through to completion instead of stopping at a suggestion. - Document and correspondence automation: ingest from email, upload or API, work out the intent, retrieve related facts from your own documents, classify, and draft the response. A person approves before anything is sent. - Planning, scheduling and routing agents: constraint-aware assignment and optimised routing, with an agent monitoring performance against plan. - Applications: claims, invoices, support escalations, compliance filings, procurement, HR casework, underwriting, contract review, dispatch and scheduling. 2. RAG Over Your Private Data - Retrieval that returns the right passage: chunking, embeddings, hybrid search, reranking, and evaluation so you know it actually works. - LLM cost and latency optimisation: caching, routing, model selection and prompt design so the system stays affordable at production volume. 3. Cloud Architecture, Cost & Security (AWS) - Full review of your AWS estate, ranked by money saved and risk removed. Around 20% typically comes off the bill from sizing and configuration tweaks alone, before any re-architecture. - AI-driven cost anomaly detection: an agent that watches spend continuously, separates a real anomaly from normal variance, explains the cause and names the fix. HOW I BUILD Every system follows the same architecture, which is why it ports to any domain: 1) ingest 2) understand intent 3) retrieve related context 4) classify 5) generate or decide 6) human approval gate 7) learn from every correction. Non-negotiables: the AI drafts and a human approves, every decision is auditable, and corrections feed back so accuracy improves over time instead of drifting. MY EXPERTISE - AI Agents: OpenAI (GPT), Anthropic (Claude), multi-agent orchestration, LangChain, RAG, intent classification, human-in-the-loop review, continuous-learning feedback loops - Back End: Python, FastAPI, REST APIs, constraint and route optimisation - Cloud & DevOps: AWS (Lambda, ECS/Fargate, RDS, S3), Docker, Terraform, CI/CD, observability and cost control WHY MY SYSTEMS SURVIVE PRODUCTION Nine years as a cloud architect on high-traffic systems, and AWS Certified Solutions Architect. Most AI projects die in the gap between the demo and the deploy. I handle both halves: the agent logic, plus the infrastructure, evals, observability and cost control that keep it working once real volume arrives. TRACK RECORD 11 Upwork contracts, 5.0 stars on every single one - the cloud-infrastructure foundation my AI systems run on. "Excellent work delivered from Akshay." / "Very good in aws and devops skills" Recent private-client systems: a legal correspondence agent and an AI field-ticket planner, each delivering roughly 5x efficiency gains. Tell me the process you want automated, or the cloud bill you want cut, and I'll tell you straight whether AI is the right tool, what it takes to build, and what it costs to run. Let's discuss your project.

I help startups, brands, and businesses build immersive, interactive digital experiences using Unity. If you're looking to create more than just an app — if you need engagement, interactivity, gamification, or simulation — I can help turn your concept into a scalable, production-ready product. 🚀 What I Build ✔ AR applications (AR Foundation – marker & markerless) ✔ VR experiences (Meta Quest, immersive simulations) ✔ Gamified mobile apps (education, fitness, training, kids learning) ✔ Interactive simulations & training tools ✔ Product configurators & visualizers ✔ 2D & 3D Unity applications ✔ MVP development for startups ✔ Android, iOS & WebGL deployment 🎯 Who I Work With • Startups building interactive MVPs • Businesses creating training simulations • Brands developing AR product demos • Agencies needing reliable Unity expertise • Founders looking to gamify their app idea 💡 Why Clients Work With Me - Strong Unity architecture & clean code structure - Focus on core engagement loop - Clear milestone planning & communication - Stable builds optimized for performance - Long-term collaboration mindset I don’t just develop features — I help shape ideas into products users actually enjoy using. 🌐 Multi-Engine Experience In addition to Unity, I’ve also developed projects using: • Roblox (multiplayer & UGC-style experiences) • Cocos Creator (2D mobile games) • Matter.js (browser-based physics games & simulations) This allows me to recommend the right technology based on your goals — not just push one engine. 🛠 Tech Stack Unity (2D/3D) AR Foundation Meta Quest VR C# Firebase REST APIs Multiplayer basics Animation systems Ads & In-App Purchases integration 📦 My Process - Understand your product goal - Define the interactive core loop - Build a stable MVP - Iterate based on feedback - Prepare for scale & launch If you're planning to build: • An AR product visualizer • A VR training experience • A gamified learning app • An interactive simulation • Or a scalable Unity-based MVP Let’s discuss your idea.
