Custom software
Greenfield builds, rebuilds, and the messy middle. JavaScript, Node.js, PHP — the stack we ship with, every day.
NerdySherpas partners with SaaS companies to architect, build, and scale the systems behind the product. Small team, senior engineers, rope bridges included.

We embed with your team like a senior squad that already knows the codebase. One sprint or eighteen months — we scope to the problem, not the calendar.
Greenfield builds, rebuilds, and the messy middle. JavaScript, Node.js, PHP — the stack we ship with, every day.
Schema design, query tuning, warehouse pipelines. Postgres, MySQL, DynamoDB, Redshift, BigQuery — picked for the workload.
REST APIs, webhooks, and Kafka/Kinesis event streams. Versioning that doesn't break customers. Third-party integrations that actually hold.
React and Next.js, backed by Node.js or PHP — whatever the codebase already speaks. Design systems too.
AWS (Lambda, API Gateway, S3, RDS) and GCP (BigQuery, Cloud Functions). Cloudflare Workers on the edge, Docker where it belongs, boring pipelines everywhere else.
Profilers, flame graphs, cold-path hunts. If your p95 is embarrassing, we'll find the why in a week.
We don't do discovery phases that turn into PowerPoints. We do short, scoped engagements with working software at every checkpoint.
You tell us what's broken, what's planned, what keeps you up. We tell you honestly whether we're the right fit. No deck, no discovery fee.
Fixed scope, fixed team, fixed timeline. You get a written plan with decisions called out, risks flagged, and a timeline that accounts for the messy parts.
You get a PR every Friday. A Loom walkthrough. A Slack channel with your engineers, not an account manager. Course-correct anytime.
Runbooks, on-call docs, architectural decision records. We train your team and stay on retainer for the first 90 days post-ship.
Most of our work sits behind the product — backup infra, ingest pipelines, billing systems. Here's one we can talk about.
Backups.so needed a ground-up rewrite of their ingest pipeline, a multi-region S3 replication layer, and six new export formats — without a visible downtime window. We shipped in 14 weeks, zero incidents.
“They didn't just ship the work — they left our team better. The architecture decisions we made with them are still the right calls a year later.”
