Most AI systems break down at the workflow level, not the model itself. I design, build, and document AI-driven systems that take unstructured inputs and turn them into structured, validated data, from end-to-end AI agents and RAG pipelines to the documentation and content that support them. With 20+ years in software development and 8+ years in technical writing and content strategy, I work at the intersection of engineering, automation, and communication. I build systems, structure them, and make them usable. What I Do 1. AI Agent Development & Workflow Automation * Build end-to-end AI agents for real business workflows * Design RAG pipelines for data extraction, validation, and generation * Work with structured outputs (JSON), prompt orchestration, and decision logic * Integrate with APIs, SaaS platforms, and internal systems * Design human-in-the-loop workflows for reliability 2. Content Strategy & Thought Leadership * Turn complex systems into clear, authoritative narratives * Write thought leadership, white papers, and long-form SaaS/AI content * Extract and structure founder and SME insights * Use story architectures and narrative depth maps for clarity and depth 3. Technical Documentation & Systems Design * Create developer docs, SDK guides, and knowledge bases * Build scalable documentation frameworks * Standardize structure, terminology, and workflows * Align documentation with product and business goals Selected Experience 1. AI Agent & Workflow Systems (Internal Platform): Designed AI workflows using RAG pipelines to process unstructured inputs, extract and validate data, and support downstream automation. The same system powers my documentation and content workflows. 2. AI Conversational Agent Startup: Designed and wrote SDK and user documentation (Gatsby, Tailwind, Markdown 3. Cybersecurity, DataOps & DevOps: Developer documentation and long-form content on LLMs, Kubernetes, and cloud systems 4. FinTech & IaaS Platforms: Knowledge bases and documentation for AWS-based SaaS systems 5. IoT & Vector Database Startups: Standardized technical and research-driven content How I Work 1. Systems-first thinking 2. AI automation + human validation 3. Focus on clarity, reliability, and scalability 4. Comfortable across engineering, product, and business teams In Summary: I work with teams building AI-driven products and complex systems that need both technical execution and clear communication. If you need someone who can design, implement, and explain AI systems end-to-end, I’d love to collaborate.

I am an experienced robotics engineer with a focus on developing and testing novel robotic systems. I previously worked at ABB Robotics, specifically developing and testing a new collaborative robotic arm and gripper. I am highly professional, a good communicator, and always put my client's interests first. I am passionate about robotics, and this passion is what drives me daily at work. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Below is a list of my primary skills, expertise, and what I can offer: - ROS1/ROS2: MoveIt, ros_control, deployment, developing drivers for actuators and sensors. - ROS1 to ROS2 migration. - Robotics System Architecture. - ABB RobotStudio - Sensor Integration and Testing (including, but not limited to): Rotary Encoders, Force Sensors, Torque Sensors, Gyro/Acc Sensors, Hall Sensors, LiDAR, DepthCameras. - micro-ROS, embedded programming. - Sensor Fusion: Fusing multiple sensor data in a single system. - Extensive knowledge and working experience of typical robot components: Brushless DC Motors, Harmonic Drives and Slip Rings. - Development of commissioning software for robotic subsystems such as motor drives, grippers, and complete robot system. - Development of testing frameworks for robotic systems. - CAN/CANopen communication protocol and EtherCAT, ros_canopen.

What does real business transformation mean? It means building AI systems that create operational and resource leverage, and avoiding shiny object automation. It means connecting intelligent infrastructure to the workflows that truly generate revenue. It means measurable ROI, clear outcomes, and systems that show their value. I design and deploy production-grade AI and automation systems for companies serious about upgrading how they operate. The objective is simple: - Reduce manual friction - Increase speed of execution - Improve conversion and decision quality - Build infrastructure that compounds over time My work typically follows three stages. 1. AI & Workflow Assessment Before anything is built, I analyze your operations and identify where AI creates concrete value. Lead qualification, research workflows, internal ops, reporting bottlenecks - the focus is on measurable impact before development begins. Clarity before code. 2. Architecture & System Design I design systems that sit inside real infrastructure: - API integrations - CRM automation - Event-triggered workflows (n8n / Make) - AI agents with memory, knowledge, and tool access - Custom backends and data pipelines These are operational systems integrated into your stack. 3. Implementation & Deployment I build and deploy at the infrastructure layer: - Dockerized services - Ubuntu servers - Reverse proxies - Deployment pipelines - Scalable backend architecture From automated lead qualification engines to AI sales copilots and SaaS backends, the goal is always the same: systems that remove recurring labor and increase output with as little resources as possible. If you need a few tools connected, I’m genuinely not the right fit. If you want AI embedded into the mechanics of your business - improving margins and execution speed, including systems training - that’s where I work best.

I have over 30 years experience in electronics and software design. My experience includes engine control units (ECUs), alarm control units, various other control modules used in vehicles, data acquisition and telemetry systems, tracking systems, handheld terminals as well as IoT data telemtry systems. I can do both PCB design and firmware, and I am equally proficient with server and web oftware using C++/.NET/ASP .NET.

AWS environments designed, deployed, and sustained. Microsoft Intune programmes built. Microsoft 365 tenants migrated. Long-term Senior Cloud Engineer engagements or finite implementation projects — I run both. 8 years on Upwork: 100% Job Success, Top Rated Plus, 11,233 hours, $400K+ earned across 35 contracts. I work with MSPs, MSSPs, and tech-mature SMBs in two patterns. Pattern one: embedded long-term Senior Cloud Engineer — I become a stable hand on your environment, the way I spent 8 years on a 168-server hybrid AWS estate. Pattern two: finite implementation projects — scope, design, deploy, validate, hand over. Both work without ramp-up. Both work without supervision. Recent reference points: - 8 years as Senior Cloud Engineer on a 168-server hybrid AWS estate (Linux + Windows) for an ASX-listed catering enterprise — CrowdStrike deployment, Oracle E-Business DR build, documented India offshore transition. December 2017 through January 2025, unbroken. - Microsoft Intune + Apple Business Manager rollouts at NWCR (Chicago MSP) — conditional access framework, Autopilot, mixed Apple/Windows fleet. - Amazon WorkSpaces and AppStream 2.0 builds at Syncronet (Houston) — application catalogues, directory integration. - Before Upwork: founded and ran my own MSP (ITRS), scaled to R5m revenue, Microsoft Silver Infrastructure Partner. Before that, Regional IT Manager at Discovery Holdings — 99.8% uptime across regulated financial services. What I deliver: - AWS cloud migrations, implementations, and ongoing operations — EC2, S3, RDS, Lambda, WorkSpaces, AppStream. Well-architected design, lift-and-shift, hybrid estates. AWS Certified Solutions Architect — Associate (verified by Upwork). - Microsoft Intune endpoint rollouts and lifecycle management — Autopilot, conditional access, configuration profiles, Apple Business Manager, BYOD/COPE programmes. - Microsoft 365, Azure, Entra ID migrations and tenant work — tenant moves, Exchange Online, SharePoint, Teams, Purview, security baselines. - MSP toolchain implementation and ongoing optimisation — Kaseya, N-Central, ConnectWise PSA + Automate, NinjaOne, IT Glue. I built my own MSP from zero, so I can architect or operate yours the same way. How engagements run: for finite projects, scope to design to deploy to validate to hand over. For long-term retainer or embedded work, weekly reporting cadence, monthly DR and security review, documented incident history. Either way, every change documented — I built the runbooks that let an India offshore team take over the AWS estate after 8 years, and I work the same way for new clients. SAST timezone (UTC+2) overlaps EU business hours, US mornings, and AU afternoons. What I don't do: application development, ML model training, or Kubernetes-first DevOps. My lane is cloud infrastructure, endpoint management, and migrations — operations and stability, not greenfield app dev. Credentials: AWS Certified Solutions Architect — Associate · Top Rated Plus · 100% Job Success Score · 11,233 platform hours · 35 completed Upwork contracts · 8 years on Upwork · ITIL Foundation · 30+ years in IT. If you have an AWS migration in scope, a stalled Intune rollout, a tenant move that needs to ship — or a senior cloud engineer slot you need filled long-term — send me the brief. I'll come back within 24 hours with whether I'm a fit and what the first 30 days would look like.
