Kalvin is the most diligent engineer in the team. Communicates frequently and takes action of every feedback we have given him. With little direction on the architecture, he built the team's E2E pipeline from scratch. Highly trainable and highly recommend!
Kalvin Calimag
Software Engineer·Dagupan, PH
I build software that quietly makes hard things easier — currently shipping hardened, audit-ready financial logic in B2B taxtech SaaS. Summa Cum Laude means I learn fast. Shipping it with full ownership means I deliver.
Always learning. Always pushing for the better solution.

- Hello, World!
Software Engineer@White Cloak Technologies, Inc.
Mar 2025 — Present· Remote
- Built solutions for a B2B taxtech platform managing $100B+ in AUM for some of the Asia-Pacific region's largest asset managers — shipping 180+ custom backend solutions across multiple areas, building secure REST APIs with Django REST Framework, offloading heavy financial calculations to Celery, and hardening reporting logic through targeted bugfixes.
- Eliminated ~40 hours of manual regression testing per month by designing and building the team's service-level end-to-end testing framework from scratch with little architectural direction — integrated into the GitLab CI/CD pipeline using Django and AWS S3.
- Earned direct praise from the founding team by improving multi-tenant operator UX with a custom tenant-switching toggle and Excel import/export actions in the admin, while strengthening platform security through corrected permission overrides and strict access controls on data snapshot tables.
- Reduced team onboarding friction by authoring comprehensive Confluence documentation for 10+ core system features.
