My core focus is designing, building, and deploying AI-driven systems—from LLM-powered agents and voice assistants to data-aware automation pipelines that integrate seamlessly with production applications. I work extensively with large language models (LLMs), retrieval-augmented generation (RAG), vector databases, embeddings, tool-calling frameworks, and agent orchestration patterns to create systems that reason, act, and scale reliably. On the backend, I build high-performance APIs and services using FastAPI, Flask, Node.js, and Django, with strong experience in async architectures, background workers, and event-driven systems. I regularly work with PostgreSQL, MySQL, Redis, MongoDB, and Neo4j, and design robust data layers using SQLAlchemy, Prisma, and ORM/DAO patterns. For AI workloads, I integrate OpenAI, Anthropic, Ollama, ElevenLabs, and custom inference pipelines, alongside Qdrant, Pinecone, FAISS, and hybrid search setups. On the frontend, I build modern, scalable interfaces using React, Next.js, Vite, Tailwind CSS, and TypeScript, with a strong emphasis on UX for AI-powered tools (real-time streaming, agent state visualization, conversation flows, and admin dashboards). For mobile, I work with React Native and cross-platform architectures to bring AI features directly into user-facing apps. Automation is a major part of my work. I design end-to-end business automation systems using Make.com, n8n, webhooks, cron jobs, message queues, and direct API integrations. This includes automating CRM workflows, email systems, call routing, lead qualification, reporting, and data synchronization across platforms like Twilio, Slack, Google Sheets, Stripe, Shopify, and internal tools. I’m highly experienced in AI voice agents and real-time systems, integrating Twilio, speech-to-text (STT), text-to-speech (TTS), streaming APIs, and conversational state management to build production-ready voice and chat agents. I also work on computer-vision and multimodal pipelines, combining vision models, tracking, and sensor data for advanced use cases. From an infrastructure and MLOps perspective, I deploy and scale systems using Docker, Linux servers, cloud VPS, CI/CD pipelines, and GPU-accelerated environments. I care deeply about observability, logging, error handling, security, and cost optimization in AI systems. Above all, I love turning business problems into automated, intelligent systems—reducing operational friction, increasing efficiency, and building products where AI is not a feature, but a core capability. If you need AI agents, automation pipelines, or full-stack systems that actually work in production, that’s exactly what I build. weniger

I have been editor/data curator for academic manuscripts at multiple stages, including copy editing, compositing/PDF output, and implementing research data sets and software. I will provide services at any production stages needed, or implement a whole workflow to convert authors' sources into professional-quality publications. As the codewriter, I can customize software for each project--every manuscript has its own workflow requirements (compiling an index, finding specific kinds of editing errors, cross-references between publications and research data sets, etc.). Sample documents may be found at my website/github repo (github.com/ScignScapePNP), including a paper and slides for my recent presentation at the NISO-JATS Conference 2026, and the chapters of my book "Innovative Data Integration and Conceptual Space Modeling for COVID, Cancer, and Cardiac Care" (Elsevier, 2022). I strongly advocate for the Diamond Open Access model (no fees for either authors or readers)--paradigmatically endorsed in terms of fairness and inclusion, but with a technological dimension as well: data sets and Executable Research Objects are easier to build when text and raw data share similar licencing and copyright specs. Granting that fees paid here are like de facto Article Processing Charges, I think we can follow a model quite close to Diamond. Commercial APCs are often very high--hard for authors to afford without institutional support (and many authors don't HAVE institutions to begin with). But custom software can reduce all production costs. I am especially eager to work with authors from nonprofit or charitable organizations, potentially in collaboration with academic institutions, or anyone addressing subjects with tangible social impact--Translational Science/Medicine, community development, sustainability, public/environmental health, animal welfare, etc. I hope to enhance partnerships between nonprofits and universities, where community-based organizations develop data sets or observations that promote scientific research, or serve as on-site implementations. Academically, I have tried to balance/combine science and humanities, with a degree in computer science but writing a doctoral dissertation involving philosophy of science, phenomenology, and cognitive linguistics. Interdisciplinary science/humanities syntheses are key to academic/nonprofit collaborations--science yields discoveries for public benefit, but humanities tells us how to deploy them. I'd love to work on material narrativizing/promoting nonprofits' activities--anything from adoption-photo calendars to sociological analyses by community groups. My own nonprofit experience: I volunteered at a refugee camp near the Thai/Myanmar border, and served on the Board of Directors for a progressive grade school in New York City. weniger
