Kris D.

I’m a senior full-stack product engineer and solutions architect with deep experience building real-world SaaS platforms from the ground up. My background spans AI, telecom, VoIP/UCaaS, customer experience systems, web applications, APIs, cloud infrastructure, and product design. I specialize in turning complex business ideas into production-ready platforms, especially where backend logic, realtime communication, and customer-facing UX all have to work together cleanly.

A big part of my work has focused on architecting and building advanced voice and communications systems using Asterisk, SIP, WebRTC, Laravel, Node.js, Vue, and modern cloud infrastructure. That includes PBX/UCaaS platforms, softphones, call routing systems, IVRs, ring groups, presence systems, voicemail, monitoring tools, websocket services, and custom telecom workflows. More recently, I’ve also been building AI-powered voice and customer interaction systems that combine telephony, live voice AI, messaging, structured runtime context, business rules, and escalation logic.

Beyond telecom and AI, I’m strong across the full product stack: backend APIs, database design, admin portals, frontend apps, cloud deployment, Docker, Kubernetes, CI/CD, system integrations, and operational tooling. I’m comfortable owning architecture, implementation, debugging, scaling, and product refinement. I also bring strong UX and product instincts, so I’m not just shipping code — I’m building systems that are usable, sellable, and aligned with business goals.

My strongest value on Upwork is helping clients with ambitious or technically difficult projects that need senior-level thinking, not just task execution. I’m especially well suited for:

AI-enabled SaaS products
VoIP / telephony / call center systems
Laravel / PHP backend platforms
Node.js realtime services
Vue / Next.js frontend applications
API and database architecture
Cloud-native deployment and infrastructure
Product strategy, system design, and rapid prototyping

I’m the kind of developer who can step into a messy or complex project, understand the moving parts quickly, and turn it into a clean, scalable solution. Whether the need is building from scratch, rescuing an existing platform, adding advanced features, or designing a new technical roadmap, I bring both hands-on implementation skill and high-level product/architecture judgment.
