Experience
Full-Stack Engineer — jasenc.dev — Sep 2024 – Present
Infrastructure & DevOps:
- Deployed two-node K3s Kubernetes cluster on Intel NUCs over Tailscale mesh VPN, enabling secure remote access to self-hosted services from anywhere without exposing ports or configuring firewalls.
- Configured n8n workflow automation platform as first cluster workload with persistent storage, NodePort services, and HTTPS via Tailscale Serve.
- Architected and deployed local-first LLM infrastructure using Open WebUI + Ollama on bare metal Ubuntu. Self-hosted Microsoft Phi-4 with custom APIs for inference, reducing cloud AI costs by over 60%.
- Secured self-hosted infrastructure using Tailscale VPN with end-to-end encryption for private network deployment.
Full-Stack Development:
- Built Bun Stack: a production-grade fullstack framework using Bun, React, and TypeScript with Drizzle ORM. Implemented SQLite fallback mechanism when PostgreSQL connections fail, ensuring zero downtime data access.
- Architected modern portfolio site using VitePress/Vue frontend with Go/Gin backend, featuring server-side rendering, automated CI/CD, and multi-platform deployment.
- Developed production-ready Flask microblogging platform with PostgreSQL backend, implementing database migrations, user authentication, and social features with comprehensive data modeling.
- Implemented full-text search capabilities using Elasticsearch for content discovery, relevance-based ranking, and fuzzy matching across large datasets.
Machine Learning & Data:
- Designed and deployed a K-means clustering-based recipe recommendation engine using Python, scikit-learn, and Streamlit. Optimized clustering using silhouette scoring and feature selection.
- Built full ML pipeline: data preprocessing, model training, containerized deployment with Docker to Railway. Achieved <1s latency under production load.
- Integrated PostgreSQL as backend for Open WebUI production environments, improving stability and scalability through optimized permissions and proper database configuration.
Platform & CI/CD:
- Implemented continuous delivery pipeline using Railway for feature branch deployments, maintaining always-deployable code and eliminating integration surprises.
- Migrated applications from Heroku to Railway, achieving 40% cost reduction while improving performance through usage-based pricing and faster container spin-up times.
Senior Quality Engineer — PCI — Sep 2023 – Present
Statistical Analysis & Data Validation:
- Lead Quality Engineer for auto-injector sustainment and new product introduction for pharmaceutical accounts (Eli Lilly, Merck, GSK).
- Developed standard operating procedures for performing statistical techniques in calculating capability of critical-to-quality attributes.
- Implemented change controls for software solutions in dose accuracy calculation, including validation of computational models and oversight of automated scale solutions.
Quality Engineering & Validation — Various Companies — 2012 – 2023
Change Control & Corrective / Preventive Actions:
- Managed cross-functional change control processes for manufacturing and quality systems, ensuring traceability and regulatory compliance.
- Led root cause analysis investigations using 8D methodology, reducing repeat deviations by 30% through systematic corrective action implementation.
- Coordinated CAPA activities across multiple product lines, maintaining FDA audit readiness and ensuring timely closure of quality events.
Systems & Process Validation:
- Managed validation of measurement systems and statistical tools for decision-making regarding sampling sizes and acceptance criteria.
- Led data gathering and analysis for various KPIs, reducing CAPA load from 150+ to 75 active items through systematic data-driven approaches.
- Performed risk-based validation planning for processes and software systems, ensuring data integrity and regulatory compliance.
- Specialized in parsing dense technical/regulatory documentation (FDA CFRs, ISO standards) and translating into validation procedures and SOPs.
