What we do
Six disciplines, one team that owns the whole stack.
We work as a single squad: product engineering, automation, infrastructure, and design in the same standup, on the same repository.
Intelligent RPA
Bots that reconcile invoices, sync ERP records, and clear ticket queues — with retries, audit logs, and human handoff.
SaaS product build-out
Multi-tenant data models, role-based access, metered billing, and onboarding flows that survive your first 10,000 accounts.
Performance rescue
Profiling, query tuning, caching strategy, and bundle surgery for products that got slow as they grew.
Systems integration
Stripe, HubSpot, Xero, Twilio, and internal legacy APIs wired together with idempotent jobs and replayable webhooks.
Platform hardening
Row-level security, secret rotation, dependency policy, and observability so on-call is quiet by design.
Engineering
Applications that stay fast on the thousandth screen.
We build on React, TypeScript, and Postgres with a typed contract between client and server. Every pull request runs unit, integration, and Playwright suites, deploys to a preview URL, and reports bundle and query budgets before review.
- Design systems in tokens, not one-off CSS
- Server-rendered routes with measurable Core Web Vitals
- Migrations reviewed like application code
Automation
Robotic process automation with an audit trail.
Our bots handle the work nobody wants: invoice matching, KYC document intake, inventory reconciliation, and CRM hygiene. Each run is idempotent, logged, and reversible, with a human review queue for the cases that genuinely need judgement.
A logistics client cut a 22-hour weekly reconciliation cycle to 40 minutes of exception review in the first quarter after rollout.
