Hire the Best Gradio Specialists

🚀 I help startups and enterprises build scalable, production-ready software with a strong focus on Java, Spring Boot, and modern backend architecture. As a Software Engineer, I have designed and delivered systems ranging from start-up MVPs to enterprise and government platforms serving thousands of daily users. My expertise is cantered around building clean, maintainable, and high-performance backend applications, while also collaborating across the full software stack whenever projects require it. What I can help you build: ✔ Java & Spring Boot Applications ✔ REST APIs & Backend Services ✔ Microservices Architecture ✔ Authentication & Security (JWT, OAuth2, Keycloak) ✔ Event-Driven Systems (Kafka, RabbitMQ) ✔ Database Design & Optimization ✔ Performance Optimization ✔ System Integration ✔ Cloud-ready Applications ✔ Software Architecture & Code Refactoring Technologies I work with include Java, Spring Boot, Spring Security, Hibernate, PostgreSQL, MySQL, MongoDB, Redis, Kafka, RabbitMQ, Docker, Camunda, Keycloak, AWS, and modern observability tools. Beyond my primary backend expertise, I have also delivered successful projects using Python, FastAPI, Django, React, Next.js, Flutter, and Supabase whenever they were the right technology for the job. 🌟 Highlights • Architected and developed the complete backend microservices platform for "Crewpr", a Dubai-based startup, designing 10+ microservices, integrating multiple third-party services, and building a scalable production system serving thousands of active users. • Contributed to digital transformation projects for Irish government organizations, including Enterprise Ireland, NEH, and Startup Ireland, building secure and scalable backend systems. • Improved the performance and scalability of Yugo, a large-scale European student accommodation platform, by developing backend features and integrating external hospitality systems including RentCafe, Student Suite, and Entrata.

I ship production code faster using Claude Code as my primary development tool. Every project I deliver, from backend APIs to full-stack web apps, is built through an AI-native workflow (Claude Code Max Plan, GitHub Copilot, Warp AI) that lets me move at the pace of a small team while maintaining 80%+ test coverage and CI/CD from day one. Currently building AI-powered services for two Fortune 500 companies: an actuarial data processing API (FastAPI, Azure DevOps) for a global reinsurance firm, and cloud infrastructure for a major insurer's 10,000-employee desktop migration (Azure VDI, Terraform). WHAT I DELIVER AI Agents & LLM Systems: Built a multi-scope contextual memory platform for autonomous AI sales agents using FastAPI, AWS Bedrock, OpenSearch Serverless, and LangChain. RAG pipelines, vector search, prompt engineering, embeddings, and deploying LLMs to production with proper error handling and monitoring. OpenAI, Claude API, Deepgram, and AWS Bedrock integration. I build agents that persist memory, learn user style, and operate autonomously. Full-Stack AI Development: MERN stack, Spring Boot (Java 21), Python (FastAPI, Django), Next.js, React Native. From database schema to deployed frontend, I own the entire stack so you coordinate with one person instead of three. Built and maintain FocusHive (focushive.app), a live multi-service platform with Spring Boot microservices and a Next.js frontend. 1,376+ tests across my Stripe integration toolkit alone. Claude Code & AI-Native Workflow: Claude Code Max Plan is my daily driver for architecture decisions, complex refactoring, TDD, and debugging. Combined with GitHub Copilot and Warp AI, I deliver at a velocity that typically requires a 2-3 person team. This isn't a gimmick; it's how I maintain quality at speed across 59 delivered contracts. DevOps & Cloud: Azure DevOps pipelines, Docker, GitHub Actions, Terraform. Designed hub-spoke Azure infrastructure with ExpressRoute, Firewall rules, and multi-region DR for an enterprise migration. Multi-environment deployments with monitoring and automated rollbacks. MLOps: Production NLP pipeline processing 1,000+ daily messages with OpenAI + VADER fallback, delivering 60% reduction in manual moderation and 70% cost savings. Experience with AWS Bedrock inference, embedding pipelines, vector database management (OpenSearch, Pinecone, Chroma), and model monitoring. BEST FIT FOR - Teams that want an AI-native developer who ships fast with Claude Code - Companies building AI agents, RAG systems, or LLM integrations - Enterprise API development with compliance requirements (GDPR, SOX, HIPAA) - SaaS product development from database to deployment Available 30-40 hours/week for dedicated engagements. Timezone: IST (UTC+5:30), flexible overlap with US/EU/Canadian hours.

I’m Mohammed — an AI Systems Architect, Software Engineer, Certified Requirements Engineer, and senior WordPress/WooCommerce expert with 16+ years of experience building business-critical digital platforms. Today, I help businesses design and build practical AI systems: AI agents, RAG assistants, automation workflows, LLM-powered apps, internal tools, and AI features connected to real business processes. My advantage is simple: I combine deep software engineering experience with modern AI engineering, so the result is not just a chatbot demo — it is a usable, maintainable, and business-focused system. 💡What I build: ✅ AI agents that reason, use tools, automate tasks, and connect to business systems ✅ RAG assistants that answer from documents, PDFs, websites, knowledge bases, or internal data ✅ LangGraph, CrewAI, AutoGen, and OpenAI Agents SDK workflows ✅ n8n automation connected to Gmail, Google Sheets, Google Drive, CRMs, APIs, Stripe, Telegram, and business tools ✅ AI-powered chatbots for support, education, sales, HR, operations, and e-commerce ✅ Python, FastAPI, Streamlit, Gradio, and API-based AI applications ✅ AI features inside WordPress, WooCommerce, LMS platforms, SaaS products, and existing web systems Whether you need an AI assistant trained on your company data, an automation workflow that saves hours every week, or a production-ready AI-powered web application, I can help plan it, build it, test it, and improve it. 💡Core AI & Automation Expertise: • AI agents and multi-agent systems • Retrieval-Augmented Generation (RAG) • Vector databases and semantic search • LangChain and LangGraph • OpenAI API, Anthropic/Claude, and open-source LLMs • n8n AI automation workflows • Prompt engineering and structured outputs • Tool calling and function calling • AI-as-a-judge evaluation workflows • LLM/RAG evaluation and quality improvement • Fine-tuning concepts, QLoRA, Hugging Face, and model benchmarking • Speech recognition, transcription, and audio intelligence • Responsible AI, privacy guardrails, and risk-aware AI implementation I think about AI systems from both sides: the technical architecture and the business outcome. That means I care about reliability, cost, latency, UX, maintainability, data privacy, and measurable value. 💡Relevant AI Systems I've Built (My portfolio includes): • Evaluated RAG knowledge workers for business Q&A • LangGraph support agents with persistent memory • n8n automation agents for accounting, SEO, legal operations, and real estate workflows • Multi-agent deep research systems with planning, web search, reports, and email delivery • AI privacy guardrails for safer ChatGPT use in business teams • AI meeting and call intelligence tools using speech recognition • AI interview coaches, course tutors, and knowledge-base chatbots • AI agents using CrewAI, AutoGen, OpenAI Agents SDK, LangGraph, and MCP-style tool integrations 💡WordPress, WooCommerce & Web Engineering Background: Before focusing deeply on AI engineering, I spent 16+ years building and improving WordPress, WooCommerce, and custom web platforms. I have hands-on experience with custom plugins, themes, WooCommerce workflows, LMS platforms, booking systems, multivendor stores, memberships, LearnDash, H5P, GamiPress, ACF, Gravity Forms, Elementor, Divi, Gutenberg, CRM integrations, payment gateways, APIs, performance optimization, database debugging, custom PHP, JavaScript, React, and Vue.js. This background matters because many businesses do not need AI in isolation. They need AI integrated into their website, store, CRM, internal tools, support process, learning platform, or existing software stack. 💡Why Work With Me: When you work with me, you are not just hiring someone to write prompts or connect APIs. You are working with someone who can understand requirements, translate business goals into technical architecture, choose the right AI approach, build clean systems, connect AI with real tools and databases, and think about reliability, safety, scalability, and long-term improvement. I can help with idea validation, architecture planning, MVP development, workflow automation, AI feature integration, debugging, optimization, and scaling. 💡Let's Build: If you are looking to: ✅ Build an AI agent or RAG assistant ✅ Automate business workflows with AI and n8n ✅ Add AI features to your website, SaaS, WooCommerce store, or internal platform ✅ Turn documents, calls, emails, spreadsheets, or business data into intelligent workflows ✅ Design a practical AI system that is actually useful for your team or customers Send me a message and let’s discuss the best way to turn your idea into a working, high-impact solution.
