Fullstack Developer
Caleb Mills
Fullstack Developer with 10+ years of experience crafting innovative, user-focused web and mobile applications from the ground up. I specialize in React 18+, Next.js, TypeScript, and Node.js, building real-time collaborative platforms and seamless fintech integrations that eliminate tedious manual tasks, accelerate team productivity, and let mortgage professionals stay focused on high-value work.
As a passionate lifelong learner and creative problem-solver, I thrive on anticipating future needs, experimenting with new approaches, and exploring modern tools (including AI-assisted workflows) to deliver clean, high-performance solutions quickly. I stay current with cutting-edge technologies by regularly rebuilding personal projects with new frameworks and concepts.
Skills
Experience
Software Developer
KensieMae, LLC, Remote
- Independently designed, architected, and built the complete React frontend (plus significant backend contributions) for the groundbreaking “Connector” data-bridge automation platform — a flexible, generic mapping system connecting any data sources to any targets. Served ~80 clients, automated complex compliance and workflow processes that previously required 10–30+ hours of manual effort per loan, earned consistent praise for intuitive UI/UX, became the primary revenue driver, and was a key factor in Velma’s acquisition by KensieMae.
- Architected internal npm/npx scaffolding tool and migration framework that standardized web-plugin development; enabled migration of 75+ legacy desktop Encompass plugins to modern web architecture in ~6 months (versus estimated 12 months), saving the 12-person development team roughly $700K in effort and allowing focus on higher-priority features.
- Engineered multiple B2B data-mapping and automation platforms (including Total Expert Fusion and GNB FIS CodeConnect Horizon) that synchronized loan data between Loan Origination Systems (Empower/Encompass) and CRM/core banking platforms, eliminating hours of manual re-keying per loan and preventing stale data through scheduled + webhook-driven syncs.
- Designed, developed, and maintained high-performance full-stack web applications using React 18+, TypeScript, Vue/Nuxt, and C#/.NET that streamlined mortgage professionals’ workflows and dramatically reduced manual data entry and compliance work.
Software Developer
Velma.com, Nampa, Idaho
- Designed, built, and maintained scalable microservices using Node.js, TypeScript, and C#/.NET that powered the VFS marketing engine, enabling high-volume automated marketing campaigns and improving platform reliability.
- Configured and optimized AWS infrastructure (API Gateway, CloudFront, S3, Lambda, DynamoDB, CodePipeline, ECS, etc.) and implemented robust CI/CD pipelines with manual approval gates, ensuring identical code deploys from test to production and accelerating reliable releases across the platform.
- Created micro-frontend components (using module federation) for the VFS Jobs interface as a proof-of-concept, allowing seamless transplantation into other applications (Velma CRM, Connector) and laying groundwork for client-facing embeddable components.
- Developed and evolved a full-stack CRM and automation platform using C#, React, Angular, Node.js, and JavaScript, delivering ongoing enhancements that strengthened client relationships and improved daily mortgage operations.
- Delivered polished, intuitive user interfaces and smooth UX flows across all products that consistently earned positive client feedback and praise for design quality and usability.
- Contributed to long-term platform modernization and feature development that supported significant business growth, culminating in the successful acquisition by KensieMae, LLC in 2023.
