Remote US Software Engineer — overview
Sharon Rosario works as a full-stack software engineer with distributed teams across US timezones, owning features end-to-end rather than waiting on hand-offs. That means writing the React frontend, the Node.js or Python API behind it, the database schema underneath, and the CI/CD that ships it — then staying accountable for how it behaves in production.
Remote work only pays off when async communication is disciplined: clear written specs, small reviewable pull requests, and predictable overlap hours for the calls that actually need synchronous time. Sharon has built products this way as a founding engineer at getconch.ai and ilumiera.ai, where the whole team is remote and shipping speed depends on trust, not stand-up theatre.
What "full-stack" actually covers here
Frontend: React 19, TypeScript, Tailwind, and accessible, performance-budgeted UI. Backend: Node.js and Python (FastAPI), REST and event-driven services, Postgres and Redis. Infra: Docker, GitHub Actions, and deployments on Vercel, AWS, and GCP.
The value of one engineer holding the whole stack is that features do not stall at integration boundaries. A change to an API contract, its React consumer, and the migration that backs it can land in a single coherent pull request.
Working across US timezones
Sharon maintains a dependable daily overlap window with US Eastern and Pacific teams for reviews, pairing, and incident response, and runs the rest of the day async so work does not block on a single timezone. Decisions get written down, not lost in a call.

Sharon regularly collaborates with US-based teams and maintains a reliable overlap window with US Eastern and Pacific hours for meetings, code review, and incident response, while running the rest of the work asynchronously.
Full-stack and founding-engineer roles at startups and product teams — anywhere ownership of features from database to UI, plus the deployment pipeline, matters more than a single narrow specialty.
Written specs, small and frequent pull requests, documented decisions, and a fixed overlap window for synchronous work. Everything else is handled async so progress never depends on a single call.
