I design and ship backend systems end-to-end —
from ADRs to production at scale.
Design. Ship.
Scale.
I'm Paritosh Tripathi — a backend engineer with 4 years building microservices, distributed systems, and event-driven architectures in Python and Go. Currently Software Engineer II at Sharpsell, building a multi-tenant ClickHouse + dbt analytics platform. Previously at Parspec (saga-based inventory, public API, ERP integrations, ephemeral environments) and Anakin (YC S21). I design and ship backend systems end-to-end — from technical design and ADRs through production, scaling, and observability.
Six systems.
End to end.
Each one designed, shipped, and run in production. Click in for architecture, decisions, and the numbers.
