He showed competence in a wide variety of topics including HTML, CSS, JavaScript, SQL, web serving devops, and React." - US-based Sales Engineering team, Twilio assessment I am an AI developer and full stack developer who has been building production systems for 10 years across FinTech, GovTech, healthcare, and consumer SaaS. My AI developer stack covers AI agent development with LangChain and OpenAI, LLM integration, RAG pipelines, and n8n workflow automation. As an AI developer my full stack foundation is Python, Node.js, TypeScript, and React - every AI system I build as an AI developer sits on a properly architected application, not a loose script. An AI developer who can also build the full stack is different from one who can only write prompts. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗙𝗹𝗮𝗴𝘀𝗵𝗶𝗽 𝗔𝗜 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 𝗽𝗿𝗼𝗷𝗲𝗰𝘁𝘀 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ AI video agent for French tutoring - one of the first conversational AI developer builds for children, combining LLM, TTS/STT, and animated 3D avatar ▸ Rewrote a 14-year legacy Go backend to Node.js in 6 months as a solo AI developer using AI tooling, without prior Go expertise ▸ BIMSafe - national SaaS platform for the Barbados Ministry of Health managing COVID-19 travel protocols ▸ VR surgical training tool for a Silicon Valley startup, AI developer on the simulation system ▸ Social media SaaS from scratch to 10,000+ monthly users - AR, Amazon TV, Apple Watch, 10+ social API integrations ▸ ERP that reduced financial staff by 4x through automation ▸ Flutter mobile app for the Qatar Ministry of Foreign Affairs, currently in production ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗪𝗵𝗮𝘁 𝗜 𝗯𝘂𝗶𝗹𝗱 𝗮𝘀 𝗮𝗻 𝗔𝗜 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ AI agent development - multi-agent systems, tool-using LLM agents, and autonomous workflow agents built with LangChain and OpenAI. As an AI developer I design agent architecture before writing a prompt so the system has clear scope, fallback paths, and observable behavior in production. LLM integration and RAG pipelines - as an AI developer I build retrieval-augmented generation systems that answer from company knowledge bases with source attribution and hallucination guardrails. n8n automation - as an AI developer I build n8n workflow systems connecting AI agent outputs to CRMs, email platforms, databases, and APIs in multi-step pipelines with error handling and retry logic. WebXR and AR/VR - as an AI developer in spatial computing I build immersive AI applications on Magic Leap 3 and WebXR across medical simulation, consumer, and enterprise training. Full stack AI applications - as an AI developer and full stack developer I build the React frontend, Python or Node.js backend, and AI layer as a connected system with consistent data contracts, logging, and deployment infrastructure. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗪𝗵𝗼 𝗜 𝘄𝗼𝗿𝗸 𝗯𝗲𝘀𝘁 𝘄𝗶𝘁𝗵 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Founders and product teams who need an AI developer who takes end-to-end ownership - not an AI developer who hands off a demo and disappears. Companies that tried off-the-shelf AI tools and found they do not fit their domain. Startups that need an AI developer who can scope the system, build it, and deploy it without daily management. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗪𝗵𝗮𝘁 𝘆𝗼𝘂 𝗴𝗲𝘁 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Every AI developer engagement starts with a scoping call to define what the system does, what it connects to, and what production-ready means for this specific build. You get an AI system with logging, error handling, and documentation - not a demo that breaks the first time edge cases appear. Message me, I respond same day and every project starts with a plan, not a prompt.

Every hour of downtime costs your enterprise an average of $540,000. That's not a DevOps metric - that's a board-level problem. I design and operate infrastructure that stays up. My specialty is the full observability and reliability stack: detecting failures before users do, recovering in minutes, not hours, and building the self-healing systems that let your engineering team sleep at night. With $400K+ earned on Upwork, 100% Job Success Score, and 10+ years in DevOps and Site Reliability Engineering, I bring the broadest monitoring stack you'll find in one engineer: Prometheus · Grafana · Datadog · ELK Stack · Zabbix · Sumo Logic - combined with deep Kubernetes and cloud expertise. Typical Problems I Solve → Production incidents are frequent, and MTTR is too high → No observability - issues discovered by users, not monitoring → Need DevOps engineer for high availability infrastructure setup → Kubernetes clusters experiencing performance or reliability issues → Disaster recovery plan missing or untested → AI workloads need reliable, observable infrastructure Proven Client Results ▪️ iLost Platform (Netherlands) → Challenge: EKS performance degrading, CI/CD unstable across Dev/Staging/Production, and OpenSearch causing timeouts. → Solution: EKS rightsizing, CI/CD pipeline optimization, IAM hardening, OpenSearch performance tuning. → Business Impact: Reduced bottlenecks, improved release predictability, and optimized infrastructure costs. ▪️ Qopla Infrastructure → Challenge: Long-term SRE engagement - ongoing reliability, monitoring, and performance needs. → Solution: Continuous SRE operations, incident management, and infrastructure optimization. → Business Impact: 657-hour engagement demonstrating sustained impact. Rate progressed $40/hr → $52/hr based on results. ▪️ GetChecked (Blockchain / Multi-cloud) → Challenge: Multi-cloud infrastructure (AWS + DigitalOcean + bare-metal) with Hyperledger Fabric in a regulated environment. → Solution: Upgraded Hyperledger Fabric, implemented monitoring, backup, DR/BCP, optimized CI/CD pipelines. → Business Impact: Increased system reliability and security in a strict regulatory context. Core SRE Capabilities → DORA metrics: Deployment Frequency, Lead Time, MTTR, Change Failure Rate - measured and improved → Incident Management & On-Call: Runbooks, escalation paths, post-mortems → Disaster Recovery & Business Continuity planning and testing → Zero Trust Security: IAM, RBAC, SELinux, network hardening → High Availability: Multi-AZ, failover, load balancing, autoscaling → AI workload reliability: observability for ML pipelines and LLM infrastructure Stack: AWS · GCP · Kubernetes · Terraform · Ansible · Prometheus · Grafana · ELK Stack · Datadog · Zabbix · Docker · Linux · GitHub Actions · GitLab CI · Incident Response Plan · Disaster Recovery Available during US business hours (EST/PST overlap). Downtime is a solved problem - if you have the right observability. Send an invite and let's audit your reliability posture.
