Senior Full-Stack Developer | GenAI, LLM & Agentic AI | Automation

I build end-to-end software and AI-powered products, from full-stack platforms to LLM-driven features and automation systems that eliminate manual work. With 6+ years shipping production systems across enterprise (Accenture Federal Services), fast-moving startups (Swiftly), and open-source teams, I don't just write code. I take ownership from product logic all the way to production. I focus on delivering 𝐫𝐞𝐚𝐥, 𝐫𝐞𝐥𝐢𝐚𝐛𝐥𝐞 𝐬𝐨𝐟𝐭𝐰𝐚𝐫𝐞 - not fragile prototypes or one-off demos. ✅ 𝐖𝐡𝐚𝐭 𝐈 𝐂𝐚𝐧 𝐇𝐞𝐥𝐩 𝐘𝐨𝐮 𝐁𝐮𝐢𝐥𝐝: - 𝐆𝐞𝐧𝐀𝐈 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬: Claude / OpenAI / Azure OpenAI integrations, AI copilots, agentic AI workflows - 𝐅𝐮𝐥𝐥-𝐒𝐭𝐚𝐜𝐤 𝐀𝐩𝐩𝐬: React / TypeScript / Angular frontends + Java, Scala, Python, Node.js backends - 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧 𝐒𝐲𝐬𝐭𝐞𝐦𝐬: CLI tools, Slack bots, serverless workflows that cut hours of manual toil - 𝐁𝐚𝐜𝐤𝐞𝐧𝐝 & 𝐀𝐏𝐈𝐬: scalable REST APIs, microservices, event-driven systems (Kafka, Spring Boot) - 𝐂𝐥𝐨𝐮𝐝 & 𝐃𝐞𝐯𝐎𝐩𝐬: AWS (Lambda, Serverless), Azure, Terraform, Docker, CI/CD - 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫 𝐄𝐱𝐩𝐞𝐫𝐢𝐞𝐧𝐜𝐞 𝐓𝐨𝐨𝐥𝐬: internal tooling adopted org-wide by 60+ engineers 💼 𝐄𝐱𝐩𝐞𝐫𝐢𝐞𝐧𝐜𝐞 𝐇𝐢𝐠𝐡𝐥𝐢𝐠𝐡𝐭𝐬: - 𝐀𝐜𝐜𝐞𝐧𝐭𝐮𝐫𝐞 𝐅𝐞𝐝𝐞𝐫𝐚𝐥 𝐒𝐞𝐫𝐯𝐢𝐜𝐞𝐬 - building GenAI features and developer tooling; leveraged agentic AI (Claude Code) to 𝐭𝐫𝐢𝐩𝐥𝐞 𝐝𝐞𝐥𝐢𝐯𝐞𝐫𝐲 𝐭𝐡𝐫𝐨𝐮𝐠𝐡𝐩𝐮𝐭 across 3 teams - 𝐒𝐰𝐢𝐟𝐭𝐥𝐲 - built 𝐍𝐀𝐒𝐀(New Agency Scripts Automation), an automation platform that cut agency integration time from *days to under 10 minutes - Led code-quality upgrades achieving 𝟗𝟎%+ 𝐞𝐥𝐢𝐦𝐢𝐧𝐚𝐭𝐢𝐨𝐧 𝐨𝐟 𝐜𝐫𝐢𝐭𝐢𝐜𝐚𝐥 𝐯𝐢𝐨𝐥𝐚𝐭𝐢𝐨𝐧𝐬 across 14 repositories - Awarded the 𝐅𝐅𝐄 𝐎𝐩𝐞𝐫𝐚𝐭𝐢𝐨𝐧𝐬 𝐒𝐩𝐨𝐭 𝐀𝐰𝐚𝐫𝐝 (𝟐𝟎𝟐𝟔) for technical leadership and measurable impact 📊 𝐖𝐡𝐚𝐭 𝐘𝐨𝐮 𝐆𝐞𝐭 𝐖𝐨𝐫𝐤𝐢𝐧𝐠 𝐖𝐢𝐭𝐡 𝐌𝐞: - End-to-end builder - AI + full-stack + automation in one engineer - Production-ready systems, architected to scale from day one - AI-accelerated development using Claude Code, agentic AI, and modern tooling - Clear communication, strong product judgment, and predictable delivery - Comfortable joining existing codebases, fixing complex issues, and shipping fast 🔧 𝐓𝐞𝐜𝐡 𝐒𝐭𝐚𝐜𝐤: 𝐀𝐈: Claude, OpenAI, Azure OpenAI, Agentic AI, LLM integration, RAG, prompt engineering, AI automation 𝐅𝐫𝐨𝐧𝐭𝐞𝐧𝐝: React, TypeScript, Angular, Vue.js, HTML/CSS 𝐁𝐚𝐜𝐤𝐞𝐧𝐝: Java, Scala, Python, Node.js, Spring Boot, REST APIs, microservices 𝐂𝐥𝐨𝐮𝐝 & 𝐈𝐧𝐟𝐫𝐚: AWS (Lambda, Serverless), Azure, Terraform, Docker, Kafka, ArgoCD 𝐃𝐚𝐭𝐚𝐛𝐚𝐬𝐞𝐬: PostgreSQL, MongoDB, SQL 🎯 𝐈𝐝𝐞𝐚𝐥 𝐏𝐫𝐨𝐣𝐞𝐜𝐭𝐬: - AI copilots, chatbots & agentic workflows - Full-stack SaaS MVPs and platforms - Automation tooling that eliminates repetitive manual work - Backend/API systems and developer experience improvements I'm a 𝐧𝐚𝐭𝐢𝐯𝐞 𝐒𝐩𝐚𝐧𝐢𝐬𝐡 and 𝐟𝐥𝐮𝐞𝐧𝐭 𝐏𝐨𝐫𝐭𝐮𝐠𝐮𝐞𝐬𝐞 speaker with 𝐧𝐚𝐭𝐢𝐯𝐞-𝐥𝐞𝐯𝐞𝐥 𝐄𝐧𝐠𝐥𝐢𝐬𝐡 - flexible across time zones and easy to work with.
