What I love most is taking a messy, repetitive process and turning it into a clean automated pipeline: an LLM that reads the documents, makes the routine decisions, calls the right tools, and hands a human the two percent that actually needs judgment. What I do: AI agents & automated workflows — LLM-powered systems that qualify leads, process documents, answer questions over your data, and take repetitive work off your plate. RAG systems — retrieval over your docs, policies, or knowledge base with grounded, accurate answers (ChromaDB, embeddings, semantic chunking) Tool & API integration — connecting LLMs to Gmail, Calendar, CRMs, and internal systems through clean, least-privilege interfaces, including MCP servers LLM app development — Anthropic Claude, OpenAI, and local/on-device models (Ollama, MLX), from prototype to working system My background: I've built a 35,000-line multi-agent engine that runs autonomously, a from-scratch MCP server exposing developer tools to AI agents, a local-first copilot with human-in-the-loop approval controls, and an on-device mobile AI assistant. I've published fine-tuned model adapters on HuggingFace and deployed agentic systems on AWS Bedrock. My path into engineering started with exactly this itch: automating an accounts-payable workflow that was eating hours of people's days on work that required almost no real decisions. I move fast, communicate clearly, and I'm as comfortable scoping a vague idea as I am hardening an existing pipeline. Tell me what you're trying to accomplish and I'll tell you honestly whether I'm the right fit and how I'd approach it.

I build and scale production web applications—from architecture and APIs to polished frontends, integrations, and deployment. As a senior hands-on developer, I help companies turn complex workflows into reliable, maintainable products. My core services include: • End-to-end SaaS platforms, marketplaces, and internal business systems • Backend and API development with PHP/Laravel, Go, and Node.js • Frontend development with Vue.js, React, JavaScript, HTML, and CSS • AI/LLM, voice, telephony, payment, and third-party API integrations • Real-time systems using WebSockets, Redis, and event-driven services • PostgreSQL data modeling, performance optimization, and complex business logic • Existing codebase analysis, feature development, bug fixing, and modernization • Docker-based deployment, CI/CD, monitoring, and production support Recent work includes a real-time Voice AI SaaS platform for the US market, an operational platform connecting WMS, ERP, and TMS workflows for an international logistics company, a Go backend for a real-time trading system, and multilingual marketplace and restaurant products. I have worked as a Technical Lead, CTO, and Software Architect, but my primary focus remains hands-on development. I can own a product from initial technical discovery to production, join an existing engineering team, or take responsibility for a complex subsystem. Core stack: PHP, Laravel, Slim, Go, Node.js, JavaScript, Vue.js, React, Python, PostgreSQL, MongoDB, Redis, REST APIs, WebSockets, Docker, Git, and CI/CD. If you need a senior developer who can understand the business problem, make sound technical decisions, and deliver working software—not just isolated code—let’s discuss your project.

I build production-ready apps and integrations, and I ship fast. To show what that looks like: as a solo developer I built Chef Pip from scratch, a full family cooking app in 8 languages with an enterprise-grade backend and a 16-step generation pipeline. That is one proven project, but it is just a sample of what I can do. Here is the fuller picture of what I ship: Chef Pip — Family cooking app, live on iOS and Android. Gamification, daily challenges, multiple subscription tiers, 51,000+ lines of code, 8 languages. Vondi — A thrifting and resale scanner app with smart item recognition and live eBay pricing. Built for the EU market including Marktplaats and Vinted. MoviByte Studio — My studio and public-facing brand for client work: websites, mobile apps, integrations, and business automation. Flightdeck for macOS — Open-source self-hosted voice operations deck for your own agents. Persistent memory, terminal access, web search, LLM routing across multiple providers, a multi-model deliberation council, and a six-panel browser HUD. Speech recognition runs fully local. 290 tests, native Swift companion apps, launchd integration. What I can build for you: Features and LLM agents (chatbots, RAG, automation, smart pipelines) Mobile apps (React Native / Expo) and web apps (Next.js / React) Backends, APIs and databases (Supabase / Postgres, Node, edge functions) Payments and subscriptions (RevenueCat, Stripe), integrations and third-party APIs MVPs, prototypes, and improvements to existing products Stack: TypeScript, React Native/Expo, Next.js, Node, Supabase/Postgres, OpenAI/Gemini/Claude, Stripe/RevenueCat, Python/FastAPI. I combine engineering with product thinking, so I don't just build what is asked, I help shape a better solution. Clear communication, realistic timelines, and code that actually works in production. If you need someone who moves fast and ships reliable, real-world results, let's talk.

Social Media Management Bio I can get content for your Social Media Pages and post anywhere from 1 to 5 posts per day. In the past I have noticed posting content on pages will engage customers or potential customers. I can work on a month to month basis or less. Web/Mobile Editor Bio Throughout my years in College going for Software Development, I picked up so skills. I've worked on my own website as well as other companies who needed to hire a new web developer. I've turned websites into a more responsive or mobile friendly pages. I can work on mostly any websites including Joomla, Wordpress, and more. Please keep in mind I can only edit the cosmetics of the websites. This is wording, the page design such as background colors, adding social media links, and more. Music Bio I have over 15 years of producing beats, rapping, and singing. The genre's I can work with is Hip Hop, Pop, and R&B. I've done countless music such as short films, a web series, a mobile app advertisement campaign and more. I've caught the attention of MTV supervisor Jen Schwartz out of New York back in 2009. Missy Elliot follows me on twitter @kayskeem after hearing one of my beats and I've done a song with the rapper Mims we're fb friends. Although I sing and rap I do not write anything but it will seem as if I wrote it. I've designed music websites (Beat Website) just to show my talent in beat making and helped design a music streaming website & app on android (ios is under maintenance) just to show my work as an artist. I've also produced music for my small business commercials. I can send links of all my work upon hire.
