Composable platform engineering
Service meshes, event streams and contract-first APIs that interlock like Lego. Designed for multi-product roadmaps without rewrites.
Non-trivial systems · Real finance
We design & build platforms for real-world finance.
We create and develop platforms for Non-trivial systems. Real finance technology. Engineering composable platforms across BaaS, Trading, Payments & Web3 with deterministic reliability, verifiable design and pragmatic velocity.

Capabilities
Deterministic reliability
Golden paths, chaos drills and SLOs as first-class citizens. We build for observability by design and predictable MTTR.
Verifiable design
Architecture runbooks, traceable decisions and automated conformance checks. When audited, it just passes.
Pragmatic velocity
Thin slices, platform scaffolds and paved-road tooling to ship weekly without heroics.
Finance-grade primitives
Idempotency, ledgers, reconciliation, limits & controls, risk scoring, settlement and compliance adapters.
Web3 & RWA enablement
Ethereum/Rust stacks, custody bridges, tokenization flows and hybrid indexers with on/off-chain proofs.
Operating principles
Deterministic reliability
SLOs, budgets and automated rollback. Reliability as a product feature.
Verifiable design
Docs, ADRs and runnable blueprints that align execs, auditors and engineers.
Pragmatic velocity
Bias for impact, not trend-chasing. We optimize for time-to-value.

Project starter
We’ll workshop goals, constraints, SLOs and a first thin slice. Deliverables: blueprint, milestones, and risk map.
Typical duration: 1–2 weeks
Platform review
Independent review of your current architecture with actionable, prioritized recommendations.
Includes: reliability, security, data, cost & operability
