💲 Who Is David Grace ?

Im a Software Engineer , I strive to stay as stack- and domain-agnostic , but I must confess I have a unintentional affinity for Enterprise Payment Infrastructure & BFSI

💲 How I Build ( Full Lifecycle Engineering ) ?

  1. Full Lifecycle Engineering:

    • Case study → Mental Mapping → HLD/LLD → Prereq Analysis → Lean e2e MVP with TDD & docs
    • TestOps → OSS Hygiene → Shipping -> DevOps → IaC → Cloud benchmarks → SRE & observability → Full product ownership

  2. Quality Engineering, Not Just Coding:

    • DRY, KISS, SOLID ; Modular by default (monolith or microservices).
    • Nuanced tradeoffs—never overengineering. & Robust exception handling, strong test suite

  3. FLOSS Advocacy & Governance:

    • All flagship products are FLOSS (MIT), modeled after Linux/Oracle-grade repositories.
    • Self-governed, community-driven, with strong vision and enterprise infra.

I Mirror Industry Standards So the Onboarding Is So Seamless I Contribute From Day #1

💲 Domain Expertise

  • Payments: UPI, ISO 8583, ISO 27001 , ISO 20022 , idempotency, ledger flows , HMAC SHA 256
  • Compliance: PCI-DSS, KYC/AML, audit logging , RBI NPCI , FEDERAL RESERVE

💲 Where Do I See Myself Down the Lane ?

Quant Finance · HPC Systems · High-Frequency Trading (HFT)
