Power Systems Study | Arc Flash | Protection Coordination | Load Flow | EasyPower | SKM | PowerWorld When your electrical system needs rigorous analysis — whether you're commissioning a new industrial facility, upgrading aging infrastructure, achieving regulatory compliance, or validating a design before construction — you need a power systems engineer who can take your existing documentation, build an accurate simulation model, and deliver results your reviewing engineer can stand behind. That is exactly what I do. I work as your dedicated power system analyst. You provide the data — SLDs, equipment nameplates, utility fault information, and your project scope. I deliver fully modeled, thoroughly analyzed, and professionally documented study reports, ready for review, approval, and submission by your licensed or chartered engineer of record. I do not provide licensed engineering stamps or country-specific certifications. My role is rigorous technical analysis and documentation that gives your approving authority — whether a PE, CEng, or local regulatory engineer — a complete, defensible package to work from. Services & Deliverables Arc Flash Hazard Analysis Applicable frameworks: IEEE 1584-2018, NFPA 70E, IEC standards, and equivalent national regulations Full equipment and bus modeling from your provided SLDs and equipment data Short circuit study as the analytical foundation for incident energy calculations Incident energy levels and arc flash protection boundaries at every studied bus Arc flash warning label dataset ready for panel installation Final hazard analysis report structured for regulatory submission or internal safety programs Arc flash analysis is relevant wherever personnel work on or near energized electrical equipment — not just in the US. If your facility operates at medium or low voltage and workers interact with electrical panels, switchgear, or distribution equipment, this study protects them regardless of your jurisdiction. Protection Coordination & Short Circuit Studies Applicable standards: ANSI/IEEE C37, IEC 60909, IEC 60947, BS EN 60909, and equivalent national standards Short circuit fault current calculations at every system bus (ANSI or IEC methodology) Equipment duty verification against rated interrupting and withstand capabilities Time-current curve (TCC) development for overcurrent devices across the system Relay, fuse, and breaker coordination for maximum selectivity and fault isolation Coordination study report with recommended device settings and selectivity rationale Whether your system follows ANSI, IEC, or a hybrid standard framework, I can model and analyze it accurately. Load Flow & Power Quality Studies Applicable across all utility and industrial voltage levels Steady-state load flow for voltage profiles, equipment loading, and bottleneck identification Overloaded feeder and transformer assessment with load redistribution recommendations Cable ampacity verification and sizing with derating per applicable standards Reactive power and power factor analysis with capacitor bank placement modeling Harmonic distortion analysis and passive or active filter design studies Motor starting analysis for large motor impacts on system voltage stability Engineering Documentation & Single-Line Diagrams Design-basis and as-built SLDs in AutoCAD Electrical per ANSI or IEC symbol conventions Equipment tagging, feeder schedules, and bus labeling to your project standard Revision-ready drawing packages structured for multi-stage engineering review Who I Work With Industrial facility owners — manufacturing plants, refineries, data centers, hospitals — needing compliance studies or infrastructure assessments Electrical and EPC engineering firms — offloading modeling and study workload to a dedicated analyst while your engineers focus on delivery Utility and infrastructure developers — requiring distribution system studies for new projects or network expansions Consulting engineers — needing a second modeler for complex simulations, peer-checking, or capacity overflow Research institutions and universities — running power system simulations, FACTS studies, transient analysis, or grid integration work Oil and gas and offshore operators — requiring industrial power system analysis for hazardous area facilities Software ETAP 19/20/21/24 · EasyPower · SKM PowerTools (PTW) · PowerWorld Simulator · DigSILENT PowerFactory · PSCAD · AutoCAD Electrical Standards Applied IEEE 1584-2018 · NFPA 70E · ANSI/IEEE C37 · IEC 60909 · IEC 60364 · IEC 61936 · NEC (NFPA 70) · BS 7671 (reference) Study Types Arc Flash Hazard Analysis · Short Circuit (ANSI & IEC) · Load Flow · Protection & Coordination · Motor Starting · Harmonic Analysis · Cable Ampacity · Transient Stability · Electromagnetic Transient (PSCAD) "Mudassir is very knowledgeable and has a very good grip in PowerWorld Simulator.

Most founders don't need another developer. They need someone who can take an idea — or a half-working AI build and turn it into a real product before time and budget run out. That's exactly what I do. I'm Joel, a Full Stack AI Developer specialising in Claude Code, Base44, Lovable, Replit, and Bolt. I build production-ready AI apps, SaaS platforms, mobile apps, and AI agents for founders, startups, and agencies — shipped in days, not weeks. Clients usually come to me in one of two situations: YOU HAVE AN IDEA AND NEED IT BUILT FAST I take you from concept to a launched MVP — authentication, database, payments, and a clean responsive UI — using React, Next.js, TypeScript, Node.js, Tailwind CSS, and Supabase, with Stripe wired in so you can charge from day one. I build AI SaaS platforms, web apps, mobile apps (iOS & Android), AI agents, admin dashboards, and client portals that go live with zero technical burden left on you. YOU HAVE AN AI APP THAT LOOKS GREAT BUT BREAKS Apps built in Base44, Lovable, Replit, or Bolt often fall apart under real users — broken auth, failed payments, console errors on deployment. I specialise in inheriting and stabilising these builds: auditing the architecture, finding the root cause, fixing it cleanly, and deploying to mobile or web. WHAT I BUILD AND FIX ✅ AI SaaS MVPs — Full-stack web apps and SaaS platforms using Claude Code, Base44, Lovable, React, Next.js, and Supabase ✅ Mobile Apps — iOS & Android via React Native and Capacitor, including mobile store submission and deployment ✅ AI Agents & Chatbots — Claude API, OpenAI, RAG systems, and agentic workflows built for real production use ✅ Workflow Automation — n8n, Make, Zapier, and GoHighLevel automations connecting your tools and eliminating manual work ✅ Payments & Integrations — Stripe, Paystack, REST APIs, webhooks, and third-party integrations handled properly ✅ MVP Rescue & Debugging — Base44, Lovable, Replit, or Bolt app broken? I diagnose, fix, and ship it stable ✅ Claude Code Setup — MCP integrations, Claude configuration, and agent tooling for your dev workflow A FEW RECENT WINS → Fixed a critical Stripe webhook failure dropping paying customers on a full stack AI app — found the exact parsing bug and resolved it same day → Turned a nightmare Replit deployment with brutal console errors into a full launch in under a week → Repaired a Base44 authentication logout bug leaking sensitive user views — secured all protected routes and deployed clean → Fixed an n8n and OpenClaw automation pipeline dropping data under traffic — resolved the async payload issue end-to-end WHY CLIENTS KEEP WORKING WITH ME Fast, proactive communication — I don't go quiet mid-project. A visible win early so you feel real progress in week one. Clean, documented code your team can build on. And honest scoping — I'll tell you upfront what it takes to ship. 🏅 Top Rated | 91% JSS | 23+ projects completed | 0–4hr response Ready to turn your idea or broken build into a product people pay for? Send me a message — I'll reply within 4 hours with exactly what it will take to ship it.
