Full-stack engineer
I ship reliable APIs and restrained, fast product UIs.
Backend-first delivery with Next.js/React where users touch the metal — Postgres, MongoDB, Docker, pragmatic observability.
I treat product logic, data shape, and operability as one problem.
I'm Mingtindu Sherpa — full-stack engineer at Nnine Solutions in Kathmandu. I build Node/Express APIs, Next.js/React clients, Dockerized deployments, and care about correctness under load rather than novelty in the UI.
What I bring
- PostgreSQL/Mongo schemas with migrations, constraints, and clear ownership boundaries
- Auth that fails closed: JWT/sessions, rate limits, and auditable writes where money or grades move
- Shipping with CI/CD, structured logs, and performance checks before calling it production
Technical focus
Labels I'm comfortable defending in interviews — grouped by discipline, not vanity scores.

Selected work
Company case studies where I can share depth, and live products I deploy on my own time.
HeliCar Booking Platform
Company work (Nnine Solutions) — multi-vehicle booking: heli, car, bus — guest OTP flows, Postgres-backed pricing, and an operations-first admin.
EMIS — Education Management System
Company work (Nnine Solutions) — student records, versioned fees, examinations, marks, PDF/CSV exports — audited writes for trusted operations.
Tripora
Personal deployment — multi-vendor travel marketplace: tours, hotels, flights, destinations, and partner tooling. Live product I ship and operate end-to-end outside my day job.
Experience & education
Where I ship, what I studied, what I've verified.

- Reduced hot-path P95 latency with query review, indexes, and caching where it was safe
- Standardized auth/validation helpers across services to cut duplicate bugs
- Partnered on deploy flows so releases are reversible, not heroic

How I help
Scoped engagements — I prefer ownership over staffing aug.
API & data modeling
REST/GraphQL boundaries, migrations, auth, rate limits, structured errors
Product web apps
Next.js/React with performance and accessibility as defaults, not retrofits
Deployment & observability
Docker, CI, logging hooks, pragmatic performance checks before launch
Hiring backend-capable frontend?
I’m strongest where API contracts, data integrity, and user flows meet.
