Emmanuel Okeke
Senior Software Engineer · Monterrey, Mexico
Senior software engineer, 6 years across fintech, payments, and crypto. At Blaze (YC S24), shipped the AI CFO product and MCP tools inside the Blaze CLI, plus stablecoin cross-border rails serving 1,340+ users across 50+ countries at $45K+ monthly volume. Solo-shipping TinyOps, an AI-native guardrail SaaS with a public MCP server (13 tools, on npm). I write about the engineering decisions behind the build at okekedev.me/blog.
Headline projects
TinyOps
A declarative YAML rule engine for engineering teams. Policies as code, shadow-mode evaluation, multi-tenant by design, with first-class integrations across GitHub, Vercel, and Slack. Approximately 180k lines of TypeScript across a pnpm and Turborepo monorepo. Built and shipped solo.
- Architected the rule engine: trigger / condition / action grammar, twelve operators including glob matching, shadow to live promotion gates
- Built the agent layer: published tinyops-mcp-server (MIT, 13 MCP tools, on npm) so any AI client (Claude Code, Cursor, ChatGPT) can manage TinyOps rules in natural language
- Failure-mode discipline: 2,700+ tests across api and web (100% passing), TypeScript-strict, structured self-review on every phase
Clavo
Full-stack SaaS for Mexican tradespeople. Web platform live, iOS app pending Apple approval. Quotes, SAT-compliant invoices (CFDI 4.0), WhatsApp delivery. Built end-to-end across Next.js, NestJS, React Native/Expo, Prisma, and Postgres in a Turborepo monorepo.
- Voice-to-quote (Whisper transcription, then AI extraction) and scan-to-quote (vision-based receipt scanning)
- Stripe Mexico (MXN subscriptions), Facturapi for SAT invoicing, WhatsApp Business API, Clerk auth
Work experience
Blaze (YC S24)
Senior Software Engineer · Nov 2025 to Present · Monterrey, Mexico · Fintech / Payments
Cross-border stablecoin payment platform. Founding-team engineer (5 people).
- Shipped the AI CFO product: an agentic financial assistant with declarative per-step onboarding, verdict-gating on live data sources, and a growing tool surface (FX quotes, subscriptions, virtual accounts, disputes, customer onboarding). Built and own the eval harness that gates agent releases.
- Built and published MCP (Model Context Protocol) tools inside the Blaze CLI, letting AI agents drive real production workflows like external payouts and contact management. Same MCP experience shipped publicly on TinyOps (13 tools, on npm).
- Owned end-to-end product surface across React Native/Expo mobile, Next.js web, and NestJS/GraphQL/Prisma backend for stablecoin-powered cross-border payments serving 1,340+ users across 50+ countries at $45K+ monthly volume. Integrated USDC/USDT rails with SPEI, ACH, SEPA, PIX and a Stellar-based settlement layer.
- Delivered the B2B business dashboard with KYB-gated money movement, net-of-refunds currency-aware analytics, and payment-link revenue reporting. Hardened production auth: Apple + Google social login with account linking, CSP + report-only violation forwarding.

Writing
I publish engineering pieces at okekedev.me/blog. Selected:
The self-review loop visible in my recent commit history: write a phase, run senior-review, triage in writing, ship fixes in a separate pass.
Walk-through of the public MCP server: why guardrails fit the agent layer, the 13 exposed tools, and the honest beat on distribution.
A bug where three missing case statements silently disabled an entire class of rules. The fix was structural, not local.
A small feature the architecture happened to make easy: run the whole rule, skip the one part that bites, and count what happens.
