Senior Full Stack Developer

Merkle Capital (Cryptomind Group)

Thailand's first digital asset fund manager.

• Senior Full Stack Developer 9mo
• Full Stack Developer 2 yr

• › Launched a new fund-management product end to end — UAT and production on GCP for frontend, admin, backend, and CMS
• › Built the infrastructure-as-code platform (OpenTofu + Cloud Run): the deployed image tag lives in version control, so rollback is redeploying an older tag; production deploys are gated
• › Designed a generic deploy contract — app repos build, push, then dispatch to one shared deploy workflow; promoting the UAT image to production instead of rebuilding it
• › Migrated services from HTTPS load balancers to Cloud Run domain mappings behind Cloudflare, cutting cost and certificate toil
• › Built a sanctions-watchlist ingest: PGP-decrypted archives parsed into PostgreSQL across 10 lists, version-gated with per-list failure isolation
• › Built token & fund rule management in the Trading Terminal; Coinbase limit-order trading and automated portfolio snapshots on Celery + Redis
• › Hardened the platform: fixed user enumeration on password reset, masked KYC history, upgraded to PostgreSQL 15, added New Relic APM and GrowthBook feature flags
• › Led remediation of penetration-test findings on security headers: per-request nonce CSP (strict-dynamic) rolled out report-only across the investment site and admin, security headers owned by the apps instead of Cloudflare rules, plus edge HSTS and HTTP → HTTPS redirects
• › Rolled out DMARC across the company domains: monitor mode first to inventory legitimate senders and SPF/DKIM alignment, then raised to quarantine; traced every failing source IP in the reports to forwarding, internal relays, or our own tests, verified enforcement with controlled spoofing tests, and caught a missing DKIM key before planning the move to reject
• › Upgraded the web stack to Node 24, restored runtime env config so one Docker image serves every environment, and fixed SEO server-side rendering on a Next.js pages-router project
• › Bootstrapped a NestJS mobile backend and planned the API migration with the vendor
• › Reduced Docker image size from 10 GB → 2 GB, cutting deployment time and storage costs
• › Managed CI/CD pipelines, GitHub Actions workflows, self-hosted SonarQube, and Cloudflare Zero Trust
