🏛️ U.S.-based Software Architect — 21+ years shipping production systems I'm a hands-on software architect and full-stack engineer with over two decades of Product Development across healthcare, finance, retail, and agriculture. I architect, build, and ship complete platforms end-to-end — system design, Artificial Intelligence & Machine Learning pipelines, backend services, Web Application front-ends, and native Mobile App experiences. Most "AI projects" stall as demos. I build AI systems that survive real data, real users, and real delivery deadlines. ━━━━━━━━━━━━━━━━━━━━ ⚙️ WHAT I DELIVER 🔹 AI & Machine Learning (Production-Grade) • Local & cloud LLM orchestration (Ollama, OpenAI, Anthropic Claude) • AI Agent Development — multi-stage agents, capability-based model routing, LLM-judge validation, retry & rewrite loops • RAG pipelines with pgvector / Pinecone / Weaviate + semantic dedup • AI Audio Generation — server-side TTS rendering with on-device fallback • Computer vision: SegFormer, custom-trained YOLO, SAM, CLIP, Flux/SDXL • Strong applied-math foundation (integral calculus, optimization, numerical methods) behind every model and pipeline decision 🔹 AI App & Backend Development • AI App Development from concept to App Store / web release • TypeScript & Python services — FastAPI, Node.js, RESTful API design • DAG orchestration, BullMQ/queue workers, Postgres-backed jobs & stages • Artifact-first pipelines, worker heartbeats, stale-job recovery, MinIO/S3 🔹 Web & Mobile Development • Web Development with React, Next.js (App Router) • Native SwiftUI iOS Mobile App delivery — signed media, caching, real-time sync, subscriptions 🔹 Cloud & DevOps • AWS / GCP, Docker, Kubernetes, CI/CD, Prometheus/Grafana observability I work fluidly with distributed, cross-border teams and have supported international development initiatives — comfortable across time zones, async-first, and clear in plain English. ━━━━━━━━━━━━━━━━━━━━ 🚀 SELECTED PROJECTS ▸ Quality-Gated Real Estate Image Finishing Platform An automated pipeline turning RAW exposure brackets into MLS-ready images with zero manual cleanup. • TypeScript DAG orchestrator + Python CPU/GPU workers exposed via RESTful API • Custom-trained YOLO glass/window detector fused with SegFormer + bracket-physics blowout masks • Synthetic "flambient" relighting, constrained Flux ROI repair, super-resolution export • Autonomous judge-and-feedback loop — every image must clear a 9.3/10 bar before delivery ✅ Result: eliminated the final human cleanup pass on hundreds of images per week. ▸ Sovereign AI Spiritual Content Platform (live on the iOS App Store) A production autonomous engine generating fresh devotionals, prayers, audio & imagery every day. • Local model routing (qwen3, nous-hermes, nomic-embed) with theological + quality judges • Structured pipelines: plan → draft → validate → judge → dedupe → persist • AI Audio Generation (Chatterbox/Kokoro) + local SDXL/Flux image rendering • Native SwiftUI Mobile App with offline-capable inference and an engagement feedback loop ✅ Result: a self-running content + guidance ecosystem with predictable cost and full model control. ━━━━━━━━━━━━━━━━━━━━ 🧰 CORE STACK Languages: TypeScript, Python, SQL, Swift AI/ML: PyTorch, Hugging Face, LangChain, LoRA fine-tuning, pgvector, YOLO, SegFormer, SAM, CLIP, Stable Diffusion/Flux Backend / API: FastAPI, Node.js, Prisma, BullMQ, Postgres, Redis, RESTful APIs Frontend / Mobile: React, Next.js, SwiftUI Cloud / DevOps: AWS, GCP, Docker, Kubernetes, MinIO/S3, GitHub Actions 🏷️ Skills: Artificial Intelligence · Machine Learning · AI Agent Development · AI App Development · AI Audio Generation · Product Development · Web Development · Web Application · Mobile App · RESTful API · International Development · Integral Calculus ━━━━━━━━━━━━━━━━━━━━ 🤝 HOW I WORK • Architecture-first, then rapid MVP → production in weeks • Full ownership: infra, ML, backend, frontend — one accountable engineer • Observable systems: artifacts, metrics, graceful degradation Whether you need an AI production pipeline, an intelligent agent, a computer-vision platform, or a seasoned architect to lead a complex build, I bring engineering rigor and product sense to every line. 📩 Tell me your use case — data sources, users, and success metrics — and I'll reply with a scoped plan within one business day.

I engineer AI-driven business automation, custom SaaS platforms, and enterprise-grade Shopify solutions designed to eliminate manual workflows and slash operational overhead. Over the past 8+ years, I have built 100+ custom Shopify stores, themes, and apps. My focus is bridging the gap between artificial intelligence, custom software architecture, and e-commerce, transforming traditional business operations into autonomous, high-growth engines. I replace complexity and repetitive manual labor with intelligent, scalable infrastructure. Clients usually hire me for three things: AI Automation & Business Optimization Designing and integrating custom AI systems to handle data processing, asset generation, and operational tasks Replacing manual bottlenecks with intelligent workflows and custom AI agents tailored to specific business logic Embedding smart automation into backend management to completely remove human friction from day-to-day operations SaaS & Custom App Development Developing robust standalone SaaS products and custom applications from scratch Building public and private Shopify apps with custom business logic and deep API integrations Architecting external infrastructure that syncs seamlessly with core platforms via high-performance web architectures Advanced Shopify Plus Engineering Developing high-performance custom themes and storefronts built from scratch for maximum speed Engineering complex cart, checkout, and custom subscription contract flows using the GraphQL Admin API Replacing bloated third-party app dependencies with clean, native infrastructure and scalable architecture I approach every project as a product architect. Whether you need to launch a new SaaS platform, embed intelligent AI automation into your workflows, or engineer a high-converting enterprise store, I build systems that scale. If you are looking to eliminate manual bottlenecks, optimize your operations, and build autonomous technical infrastructure, let us build something that performs.
