Sheet 02 — About
Leading delivery,
still shipping.
I'm Mamatha Epili, AVP of Engineering at Miles Education. For twelve years I've built software people actually use — the last several leading engineering delivery for EdTech platforms serving learners at six-figure scale, while staying close to the code.
I've shipped enterprise LMS products for US CPA and CMA certification end to end: course delivery, live classes, scheduling, and platform foundations still in production today.
To stay hands-on at the frontier, I build AI systems rather than just adopt them — a published RAG engine with guardrails that run in code, retrieval pipelines that cite their sources, and tooling that gives agents safe access to real APIs. The strongest engineering leaders keep building.
Sheet 03 — How I draw a system
Five layers,
one set of contracts.
- Layer 01ClientAngular and Next.js with signals. Design tokens, not one-off CSS — a shared vocabulary a whole team can hold in their head.
- Layer 02EdgeSSR, caching and route-level guards. The cheapest request is the one that never reaches the API.
- Layer 03APINode and Go services with explicit contracts. Types generated from the handler, so the frontend cannot drift from the backend.
- Layer 04DataPostgres on Supabase, SQL and MongoDB behind one access layer. Row-level security and key custody in a single auditable chokepoint.
- Layer 05AgentsTools over the same API, read-only by default, every outbound row through one sanitise boundary. Database text is data, never instructions.
