Experience
Building across the product surface and the systems underneath.
For more than six years, I’ve worked remotely with founders, startups, and established teams, helping turn ideas and complex workflows into production software.
I’ve worked with more than 50 clients in that time and hold Top Rated Plus status on Upwork. View my Upwork profile (opens in a new tab).
My work spans SaaS platforms, backend-heavy applications, AI-enabled products, and mobile experiences. I work across the interface and the systems behind it: data, integrations, background processing, billing, and deployment.
I’m comfortable taking a product from an early brief through architecture, implementation, and ongoing iteration, as well as working within an existing codebase. I care about clear communication, practical technical decisions, and software that a team can maintain after it ships.
Engineering depth
The interface is one part of the work. Here’s what sits behind it.
Backend systems
APIs, multi-tenancy, queues, caching, integrations, billing, and realtime coordination.
Laravel / PHP · Node.js · Python · PostgreSQL · Redis
AI & document systems
Document ingestion, retrieval, structured extraction, citations, voice, and vision workflows.
Vector databases · RAG · Python services · Multimodal APIs
Product engineering
Interfaces for complex workflows, from data-heavy web products to mobile and offline-first applications.
React · Next.js · TypeScript · React Native · IndexedDB
Infrastructure & delivery
Cloud deployments, background processing, database performance, monitoring, and operational tooling.
AWS · Vercel · Coolify · CI/CD

A little
context.
I work where product thinking meets engineering: making complex workflows useful, maintainable, and ready for the real world.
