$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.

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.

Senior CMS Developer | 14+ Years Experience | WordPress • Shopify • Webflow Specialist | Building Scalable Web Solutions I build tailored, modern websites for companies & startups. No templates. Minimal plugins. Maximum performance. ⭐️ 𝐂𝐨𝐧𝐜𝐢𝐬𝐞 𝐖𝐞𝐛 𝐃𝐞𝐬𝐢𝐠𝐧 𝐟𝐨𝐫 𝐖𝐨𝐫𝐝𝐏𝐫𝐞𝐬𝐬-𝐅𝐢𝐫𝐬𝐭 𝐂𝐨𝐦𝐩𝐚𝐧𝐢𝐞𝐬 For companies building their brand on a stable and proven platform, I architect purposeful WordPress websites that clearly communicate services, products, and core values. Here, design serves precise communication, ensuring your content, not a rigid template, drives the user experience. The process begins with your strategy and content to shape a tailored digital narrative, delivering results like the 40% lead increase for a Beverly Hills real estate brokerage (see portfolio). 🕹️𝐅𝐮𝐧𝐜𝐭𝐢𝐨𝐧𝐚𝐥 𝐏𝐫𝐨𝐝𝐮𝐜𝐭 𝐃𝐞𝐬𝐢𝐠𝐧 & 𝐖𝐏-𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐞𝐝 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 I design and develop functional digital products and user-centric application interfaces that leverage WordPress as a powerful, flexible headless CMS or a robust admin framework. My focus is on efficiently launching a lean, high-performance MVP, followed by an agile development cycle that continuously delivers new, tested features directly to your live environment. This approach powers platforms like the personalized beauty subscription service for IPSY (see portfolio), handling complex user flows and subscriptions. 🛠 𝐂𝐮𝐬𝐭𝐨𝐦 𝐖𝐨𝐫𝐝𝐏𝐫𝐞𝐬𝐬 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 & 𝐏𝐥𝐮𝐠𝐢𝐧 𝐀𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞 When your vision demands a solution that generic themes and standard plugins cannot fulfill, I analyze the requirements to architect the most effective technical strategy, whether it's a deeply customized theme, a suite of custom plugins, or a headless implementation. You will receive: — Bespoke solutions, seamlessly integrated into a custom-tailored theme or deployed as standalone, optimized WordPress plugins. — Enterprise-grade code that adheres strictly to WordPress core standards, ensuring long-term stability, security, and pain-free updates. 🚀 "𝐒𝐭𝐮𝐜𝐤" 𝐖𝐨𝐫𝐝𝐏𝐫𝐞𝐬𝐬-𝐏𝐨𝐰𝐞𝐫𝐞𝐝 𝐂𝐨𝐦𝐩𝐚𝐧𝐢𝐞𝐬? I specialize in helping businesses that launched successfully on basic WordPress setups but have hit a growth ceiling due to technical debt, performance bottlenecks, or scalability limits. I guide the strategic migration to more advanced architectures (like headless or custom plugin ecosystems), resolve critical system failures, implement professional development workflows, and codify essential business logic into maintainable, documented code—turning a static site into a dynamic business engine, similar to the platform that increased online bookings by 40% for a Milan steakhouse (see portfolio). 𝐖𝐇𝐘 𝐌𝐄❓ — A thinking designer with a strong programming foundation, teaching Full-Stack Development, and mentoring junior developers for the past two years. — 14+ years of experience in designing, developing, and marketing websites. — Expertise in managing large and continuous projects. — A long-term player in the field, having logged over 3,000 hours on Upwork, primarily working with fewer than 5 clients. I focus on solving problems, starting with the person, then the problem, and finally the code. I believe some issues can be resolved without coding, as common sense is the most valuable skill. 𝐖𝐡𝐚𝐭 𝐈 𝐃𝐨: — Web Design — Re-design/Revamp/Redo/Rebrand Sites — Complex High-End Development — Incremental Ongoing Website Development — WordPress Website Maintenance — Third-party API Integrations 𝐖𝐡𝐚𝐭 𝐈 𝐃𝐨𝐧’𝐭 𝐃𝐨: — Themeforest theme tweaks and template customizations — Elementor — No-code solutions — Sites with a “need it by tomorrow” deadline Your website should earn, not burn. Ditch the decorative design. Share your business model and the one metric that drives you. We'll build a strategy that turns traffic into revenue.
