I design and build resilient, high-throughput digital systems and lightweight SaaS applications. My engineering philosophy is rooted in first-principles execution: maximizing compute efficiency, zeroing out memory bloat, and treating software as an appreciating asset rather than a cost center.

I operate both as an independent SaaS founder and a technical consultant for businesses that value high-leverage systems over architectural theater.

• FastIngest (.NET & Bun): Modular, high-throughput data ingestion pipeline utilizing PostgreSQL wire binary COPY protocol (COPY FROM STDIN (FORMAT BINARY)).
  • 15,710 items/sec database ingestion throughput on PostgreSQL 17 (a 5.4x speedup over traditional ORM batch loops).
  • Scaled 1,000-record import latency from 343.6 ms down to 63.7 ms with 0 KB GC thread allocations.
  • Organic adoption of 1,600+ NuGet downloads across 9 packages in its first 48 hours.
• keysetengine-drizzle (NPM): Database-agnostic, zero-allocation keyset (cursor) pagination and multi-column search engine for Drizzle ORM on Node.js and Bun.
  • True O(1) indexed boundary pagination with bidirectional navigation.
  • Enterprise token defense: Authenticated AES-256-GCM encryption and HKDF purpose isolation to prevent cursor tampering and schema scraping.

• StewardAxis LLC: Independent US software venture studio engineering lightweight, multi-tenant B2B SaaS platforms.
• Team Chords: Live performance and worship band management platform featuring real-time setlist synchronization, ChordPro parsing, and cross-platform mobile apps.
  • Stack: ASP.NET Core 9, PostgreSQL 17, FastIngest, SignalR, Redis 7, React Native / Expo.
• Tindahan Natin: Grassroots inventory tracking and ledger mobile app actively used by neighborhood micro-retailers (sari-sari stores) and novelty shops across the Philippines.
  • Stack: Android, Offline-First SQLite/PostgreSQL, ASP.NET Core 9, Lightweight sync architecture.

I partner asynchronously with founders, CTOs, and early-stage ventures to stabilize systems, unblock scaling walls, and cut cloud costs:

• Database Performance & Ingestion Audits: Diagnosing ORM query bloat, lock contention, and replacing slow SQL OFFSET pagination with cryptographically protected keyset boundaries.
• Micro-SaaS & Modular Architecture: Designing clean, multi-tenant monoliths in Elysia/Bun or .NET without over-engineered mediator bloat.
• API Throughput & Latency Optimization: Profiling memory allocations, zero-copy streams, and sub-millisecond network pipelines.
