With 13+ years of professional engineering experience, 6,900+ logged hours, and a consistent 100% Job Success Score on Upwork, I don't just write code — I architect robust digital infrastructure. As an AI-enabled technical lead, I take complex business applications from raw requirements and system design through to secure deployment and long-term maintenance. I specialize in intelligent SaaS platforms, custom enterprise ERP/CRM systems, and seamless business automations — combining traditional backend reliability with modern AI/LLM integration. ━━━━━━━━━━━━━━━━━━━━ 𝗪𝗛𝗔𝗧 𝗜 𝗔𝗥𝗖𝗛𝗜𝗧𝗘𝗖𝗧 & 𝗕𝗨𝗜𝗟𝗗 ━━━━━━━━━━━━━━━━━━━━ ▸ 𝗔𝗜 & 𝗟𝗟𝗠 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀 Production-ready AI workflows, RAG pipelines, custom GPT assistants, and document intelligence platforms. ▸ 𝗘𝗻𝘁𝗲𝗿𝗽𝗿𝗶𝘀𝗲 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 & 𝗘𝗥𝗣𝘀 End-to-end custom Frappe/ERPNext apps, multi-instance production deployments, and automated business workflows. ▸ 𝗦𝗰𝗮𝗹𝗮𝗯𝗹𝗲 𝗕𝗮𝗰𝗸𝗲𝗻𝗱 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 High-performance PHP (Symfony, Laravel) and Python systems, optimized with Redis, Elasticsearch, and RabbitMQ. ▸ 𝗔𝗣𝗜𝘀 & 𝗥𝗲𝗮𝗹-𝗧𝗶𝗺𝗲 𝗖𝗼𝗺𝗺𝘂𝗻𝗶𝗰𝗮𝘁𝗶𝗼𝗻 Custom REST APIs, multi-party WebRTC audio/video streaming, and third-party vendor integrations. ▸ 𝗠𝗼𝗱𝗲𝗿𝗻 𝗙𝗿𝗼𝗻𝘁𝗲𝗻𝗱𝘀 Responsive, high-fidelity interfaces built with React, Vue, and Angular. ▸ 𝗖𝗹𝗼𝘂𝗱 𝗗𝗲𝘃𝗢𝗽𝘀 Containerized development with Docker, AWS, DigitalOcean, and strict CI/CD pipelines. ▸ 𝗟𝗲𝗴𝗮𝗰𝘆 𝗠𝗼𝗱𝗲𝗿𝗻𝗶𝘇𝗮𝘁𝗶𝗼𝗻 Safe upgrades of complex legacy platforms (PHP 5 → 8, Symfony 2 → 6) while keeping business functionality intact. ━━━━━━━━━━━━━━━━━━━━ 𝗥𝗘𝗖𝗘𝗡𝗧 𝗣𝗥𝗢𝗝𝗘𝗖𝗧 𝗛𝗜𝗚𝗛𝗟𝗜𝗚𝗛𝗧𝗦 ━━━━━━━━━━━━━━━━━━━━ ✔ 𝗨𝗻𝗶𝗳𝗶𝗲𝗱 𝗘𝗻𝘁𝗲𝗿𝗽𝗿𝗶𝘀𝗲 𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺 — Custom Frappe/ERPNext v16 platform with multi-instance deployment workflows. ✔ 𝗛𝗶𝗴𝗵-𝗧𝗿𝗮𝗳𝗳𝗶𝗰 𝗗𝗶𝗿𝗲𝗰𝘁𝗼𝗿𝘆 — Scaled a directory platform with Redis caching and fast Elasticsearch search. ✔ 𝗔𝗜-𝗘𝗻𝗵𝗮𝗻𝗰𝗲𝗱 𝗦𝘂𝗽𝗽𝗼𝗿𝘁 — Intelligent email customer-support ecosystem integrated with GPT/LLM APIs. ✔ 𝗥𝗲𝗮𝗹-𝗧𝗶𝗺𝗲 𝗩𝗶𝗱𝗲𝗼 𝗙𝗶𝘅𝗲𝘀 — Solved deep multi-party WebRTC issues affecting cross-platform iOS environments. ✔ 𝗟𝗲𝗴𝗮𝗰𝘆 𝗖𝗼𝗻𝘁𝗮𝗶𝗻𝗲𝗿𝗶𝘇𝗮𝘁𝗶𝗼𝗻 — Audited and moved a monolithic Symfony system into isolated, secure, reproducible Docker setups. ━━━━━━━━━━━━━━━━━━━━ 𝗪𝗛𝗬 𝗖𝗟𝗜𝗘𝗡𝗧𝗦 𝗦𝗧𝗔𝗬 𝗟𝗢𝗡𝗚 𝗧𝗘𝗥𝗠 ━━━━━━━━━━━━━━━━━━━━ My two longest partnerships here ran 𝟭,𝟰𝟲𝟯 𝗮𝗻𝗱 𝟭,𝟰𝟯𝟭 𝗵𝗼𝘂𝗿𝘀 — over three consecutive years of high-trust collaboration. I focus on clean, standards-compliant, maintainable code. I can step into a large existing codebase, find the real infrastructure problem, design an elegant fix, deploy it securely, and keep supporting it. I use modern AI-assisted tools to speed up debugging, testing, and deployment — but architecture, security, and business-logic decisions always stay with experienced human judgment. ━━━━━━━━━━━━━━━━━━━━ 👉 Modernizing a legacy platform, adding AI to your product, or deploying an enterprise ERP?
