We engineer deterministic instruments for the post-probabilistic era.
Membran is an independent software atelier and applied AI lab based in Jakarta. We craft high-agency software where mathematical certainty and relational data integrity are non-negotiable.

Live Production v2Executive Cockpit and AI Financial Reasoning Agent. Eliminating the bank balance illusion through strict liquidity partitioning between daily Spendable runway and Locked commitments.
High-agency systems engineered without intermediary bloat.
Membran operates as an independent software studio. We do not maintain layers of account managers, slide decks, or speculative roadmaps. Every line of architecture, database query, and user interface is crafted directly by senior engineering hands.
We tackle one hard domain at a time: taking a foundational thesis from first principles to production deployment on global edge infrastructure.
Lutfi Zain
Systems architect and software engineer building at the convergence of distributed edge runtimes, deterministic financial accounting, and evaluated AI reasoning systems.
Zero-Hallucination Accounting
Large language models are forbidden from guessing numbers. All balances, planned allocations, and currency conversions are resolved by verified ACID relational queries on PostgreSQL 16 and D1 edge engines.
Open Distributed Tracing
We reject black-box AI behavior. Every specialized tool call, span latency, and token deduction is streamed live to Arize Phoenix using standardized OpenTelemetry protocols.
Sub-100ms Global Latency
Interfaces are compiled with Svelte 5 and served directly from Cloudflare global edge points. Zero bloated client-side JavaScript, sub-second time-to-first-token.
