Senior Software Engineer | AI Integration & LLM Systems | AI Video Pipelines | Full-Stack & Technical Consulting I build things most developers can't — from production AI agents and LLM pipelines to real-time video processing infrastructure, WebRTC systems, and full-stack web applications. With 22+ years of hands-on engineering experience, I operate across the full stack of abstraction: from x86/ARM assembler up to React/Next.js, and everything in between — including the cutting edge of applied AI. Where I add the most value: AI Integration & LLM Systems — My current primary focus, and one of the fastest-growing needs on the market. I design and build practical AI systems that go beyond API wrappers: autonomous code agents, voice recognition pipelines, LLM integrations using LlamaCpp and HuggingFace, Retrieval-Augmented Generation (RAG) architectures, and reinforcement learning feedback loops. If you have an existing product and need AI capabilities embedded into it properly — not bolted on — this is where I thrive. AI-Powered Video Pipelines — A rare combination: deep AI knowledge paired with deep video engineering expertise. I build the infrastructure behind AI video tools — real-time processing, generation pipelines, and streaming architectures using FFmpeg (API and CLI), Media Foundation, and custom SDKs. Whether you're building an AI video editor, a live AI-enhanced stream, or a 250–360° panoramic solution, I can own the full pipeline from capture to output. WebRTC & Real-Time AI — Real-time communication systems enhanced with AI capabilities: live transcription, translation, moderation, and analysis. Proficient in WebRTC end-to-end, with the AI layer built in from the ground up rather than patched in afterward. AI Chatbot & Agent Development — Building production-grade conversational agents and autonomous systems with custom backends, memory, tool use, and real integrations — not no-code wrappers or off-the-shelf demos. Technical Leadership & Team Consulting — Sometimes the most valuable thing a project needs isn't more code — it's the right direction. I help clients assess their engineering teams, audit existing codebases, and evaluate software stacks and architectures before committing to a costly build. Whether you're choosing between competing technology approaches, need an independent expert to validate a technical decision, or require a fractional technical lead — I can step in as a trusted advisor. I also form and coordinate small teams of specialists when a project scope requires it, matching the right engineers to the right problems. Low-Level & Systems Programming — Custom HTTP servers, Nginx modules, WebSocket implementations, eBPF, ICMP and raw IP protocols, OS kernel work, and hardware device drivers. This foundation is what allows me to optimize AI inference performance and video pipelines at a level most engineers simply can't reach. Cross-Platform Native Development — 12 years with OpenGL, plus Metal, Vulkan, and DirectX across macOS, iOS, Windows, and Linux. Experienced with Raspberry Pi and embedded/specialized devices. Web & Full-Stack — 15 years of JavaScript (React, Next.js, TypeScript, Node.js, Three.js, WebGL), 10 years of PHP (Laravel, CakePHP, MySQL), and Python/FastAPI for backend services. Additional languages & tools: C# / MSSQL, Java, Python, Qt/PyQt, Perl — all with 5+ years of production use. I'm equally comfortable building an AI agent from scratch, architecting a real-time video pipeline, advising a CTO on a critical technical decision, or assembling the right team to deliver a complex product. If your project sits at the intersection of AI and real engineering — not just prompting — let's talk.

I’m a backend and full-stack software engineer with experience building web applications, APIs, databases, automation tools, integrations, and production systems. My background includes C#, JavaScript, Perl, PHP, SQL, REST APIs, MySQL, PostgreSQL, WordPress, Linux, Azure, and Git. I focus on practical software that improves business operations, replaces manual processes, and is reliable in day-to-day use. I’m comfortable handling the full development lifecycle, including requirements, architecture, development, deployment, troubleshooting, maintenance, and user support.

Hi, I'm Asad — a Top Rated WordPress Developer with a 100% Job Success Score, 71 completed Upwork jobs, 1,500+ hours, and $10K+ earned. I specialize in Elementor, Oxygen Builder, WooCommerce, PHP, and website performance, working with business owners and agencies in the US, UK, and Canada. I build, fix, migrate, and optimize WordPress sites, and I take on three kinds of work: new builds and full site rebuilds, WooCommerce stores that need fixing or optimizing, and ongoing maintenance for owners who'd rather not think about WordPress until something needs attention. ELEMENTOR DEVELOPMENT Custom pages, headers, footers, and Theme Builder templates in Elementor Pro, built to hold up across breakpoints. When Elementor's inline styles fight custom CSS — which happens on almost every site eventually — I fix it by scoping rules to specific element IDs instead of letting global CSS bleed into sections it shouldn't touch. OXYGEN BUILDER Pixel-perfect custom builds without page-builder bloat, for clients who need more control than Elementor gives. Recently rebuilt a full site in Oxygen from the ground up for a repeat client (5-star review). WOOCOMMERCE OPTIMIZATION Checkout flows losing sales at the payment step, product pages that aren't converting, plugin conflicts, slow catalog pages. I find where customers are actually dropping off and fix that specific point rather than rebuilding what already works. ADVANCED CUSTOM FIELDS (ACF) Custom field groups, flexible content layouts, and repeater fields for sites that need structured, editor-friendly content beyond what page builders handle natively. SPEED AND CORE WEB VITALS LCP, CLS, and INP optimization, not just PageSpeed score chasing — caching, image and script optimization, database cleanup, and query-level fixes when a slow site is a database problem, not a caching problem. ALSO HANDLED REGULARLY Website migrations, including domain moves and full redesigns during migration. Technical and on-page SEO, including a completed SEO and promotion contract where the client called me "a true SEO expert" in their review. Custom forms and logic using Gravity Forms. Monthly maintenance: updates, backups, security monitoring, uptime checks. Bug fixes: plugin conflicts, white screen of death, broken layouts after updates, PHP errors. Tools I use regularly: Elementor Pro, Oxygen Builder, WooCommerce, ACF, PHP, JavaScript, WP Rocket, Cloudflare, Rank Math, Gravity Forms. If your site has an error you can't pin down, needs a rebuild that doesn't feel templated, or you just want someone checking on it every month instead of finding out about problems from a customer — send me a message.
