About me
I’m a software engineer with over 14 years of experience in software development, including Python backend engineering, production systems, and cloud technologies. My current focus is AI agents and specification-driven development—combining practical engineering experience with new ways to build reliable software. I built ArchitectOS, a multi-agent AI system that turns software ideas into structured specifications covering requirements, architecture, APIs, testing, and security. My aim is to give AI coding tools clearer instructions, reduce wasted tokens, and improve the reliability of generated software. I participate in lablab.ai hackathons to experiment, collaborate with fellow builders, and turn ambitious ideas into useful working products. I bring backend engineering, system design, and a curiosity for solving real-world problems with AI.

TableKeeper: Autonomous Dark Factory
TableKeeper is an autonomous clean-room clone of an enterprise restaurant reservation platform engineered entirely within BAND Desktop using the ArchitectOS Dual-System Factory methodology. Under extreme parallel traffic, network retries, and cross-timezone scheduling, a table must NEVER be double-booked. We achieved this through serialized SQLite WAL transactions (BEGIN IMMEDIATE;), strict interval overlap arithmetic, and idempotency key journaling. The factory topology features three autonomous seats: - @planner (ArchitectOS System-2 Blueprint Engine): Synthesizes EARS requirements, relational schemas, API contracts, and concurrency invariant checklists. - @builder (Implementation Specialist): Implements FastAPI endpoints, atomic SQLite write transactions, and offline Docker packaging. - @verifier (System-1 Deterministic Gating): Enforces multi-tier quality gates, contract audits, and 50-worker parallel race tests. During Stage 1 development, @builder's initial deferred lock was caught by @verifier's 25-thread stress test (double-booking caught). @verifier issued a formal rejection report (VERIFIER-CONC-01). @builder autonomously refactored the transaction boundary to BEGIN IMMEDIATE;. Re-testing proved zero double-booking with 100% pass rate without human intervention. We delivered all 4 graded stages: - Stage 1: Baseline service with zero double-booking guarantee and responsive UI. - Stage 2: Real-time dynamic slot availability search with in-memory interval pre-filter. - Stage 3: Multi-timezone engine (PST, EST, London, Tokyo) and atomic waitlist auto-promotion. - Stage 4: Production hardening with operational telemetry (/api/metrics) and 50-worker race tests. Builds and serves 100% offline inside a Docker container with zero outbound network.
