Portrait of Rion Angeles

Rion Angeles

Sr. Technical Program Manager

tl;dr: TPM that bridges the gap between Engineering, Product, Sales, and more.

Hey, I'm Rion, a Sr. Technical Program Manager who also thinks like a product and growth owner. 10+ years turning ambiguity into shipped programs, from moonshot manufacturing to mobile analytics, payments, and security robotics, at Google[x], Localytics, Recurly, and Cobalt Robotics. Today at Salesforce I run programs across four cloud orgs, embedding architecture standards where engineering, product, and sales meet. I've also solo-built and shipped my own SaaS products, so I make the build, buy, and kill calls, not just track them.

Products

Real products. Real users.

    Speak the Japanese you already half-know

    An AI conversation tutor that turns your passive Japanese vocabulary into active speaking. Import your Anki or WaniKani words and Sensei weaves the ones you're due to review into real spoken conversation, crediting a word to your spaced-repetition schedule only when you produce it unprompted. That recall loop is the moat: no other app closes it. Built full-stack (Next.js, PocketBase, Gemini via a provider seam, self-hosted). My current bet, in invite-gated private beta.

  • Vectorcache.ai

    Semantic caching layer for LLMs

    Serves semantically-similar prompts from cache instead of paying for another LLM call: embed the prompt, run a vector-similarity search over past prompts (pgvector), and reuse the stored answer if it clears a tunable threshold. Shipped full-stack: FastAPI engine, Next.js dashboard, a published npm SDK, and docs. Then sunset as a prioritization call. The case study has an interactive demo of the hit/miss decision.

    2025 – 2026sunset

    Financial modeling & FIRE planning

    Solo-built retirement-planning Micro-SaaS with Stripe billing wired up: an ~8,000-line client-side TypeScript engine simulating income, a full US tax model, Monte Carlo, and Git-style scenario branching, all computed in the browser for privacy and instant feedback. Sunset after concluding the FIRE market was too saturated to defend. Read the case study, or try the simplified live version.

    • Navigated high ambiguity to deliver program resolution for a login.salesforce.com service migration affecting $5.5B in revenue.
    • Managed the OCA Sales Engagement program, delivering direct architectural engagement to protect over $50M in Annual Contract Value (ACV).

  2. Independent Product Development

    Founder

    2025 – Present · San Francisco, CA

    • Vectorcache.ai: designed the architecture and built a semantic caching layer for LLMs (Python/FastAPI + Postgres/pgvector) that embeds each prompt, runs a vector-similarity search, and reuses a stored answer when it clears a tunable threshold, turning repeat queries from ~1-2s LLM calls into tens-of-ms cache hits. Shipped full-stack with a published npm SDK, then sunset as a prioritization call.
    • Exityear: solo-built and launched a high-fidelity financial modeling platform (Next.js, TypeScript) with Monte Carlo simulations and Git-style scenario branching, then deliberately sunset it after judging the FIRE market too saturated to defend.
