Audit.
Build.
Ship.
Engineering founders bet the company on — a small senior team that audits, builds and runs production systems.
What we build for founders
Audit
A precise map of risk, cost and the fastest path to shipping.
- Architecture & code review
- Delivery pipeline assessment
- Security pass
- Prioritized fix roadmap
Build
A senior team ships the product end-to-end — production systems, not prototypes.
- Product engineering
- Payments & integrations
- Infra, CI/CD, observability
- Source code handover
Platforms
The hard infrastructure founders build on — run and evolved.
- Marketplaces & acquiring
- Multi-tenant systems
- SLA & support retainers
- Roadmap engineering
Systems we shipped
Sorpa — a four-surface loyalty and bonus-payments platform
Sorpa is a production loyalty platform where customers earn and redeem bonus balances at partner venues. HASL works across its full stack: a Django/DRF backend, two React Native apps (customer and cashier), and a Next.js marketing site with a lead pipeline.
Novatars — a paid challenge platform that lives inside Telegram
Novatars is a Telegram Mini App where members pay to join a time-boxed sprint, submit daily proof of work, and compete on a live ranking with real money in the prize pool. HASL built the whole system — async backend, embedded bot, member app, and admin console.
How we work
Deep-dive before code
We read the actual system — repo, data, delivery — before proposing anything. No guesswork.
Ship in weeks, not quarters
Iterative delivery, working software early. You see progress every week, not at the end.
Documentation, not promises
Every stage leaves an artifact: audit, architecture, runbook. You own everything — no lock-in.
Transparent work, real systems
