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.

Sheet 05 — AI-native practice
I don't use AI to type
faster. I build the tools.
Most teams treat an assistant as autocomplete. I treat it as a runtime that needs contracts, conventions and a security boundary — the same things any other service needs.
# reads the Go repo, writes the Angular layer $ /bind-api users → scan router/ 7 endpoints → map primitive.ObjectID → string → emit user.model.ts → emit user.service.ts typed, injectable → audit shared components reused: 3 $ npm run build ✓ no drift
api-binder subagent
Discovers Go endpoints and structs across a sibling repo and generates matching TypeScript interfaces and Angular services. Shipped as a subagent plus a
/bind-apicommand and a conventions file.design-guardian skill
Enforces the design system on generated components: shared components before new ones, theme tokens before hex values, surrounding control-flow style matched — and a
Design Auditheader stating what was reused.mcp-bridge-tools skill
Codified conventions for wrapping a REST endpoint as an MCP tool, so adding
get_ordersis a repeatable ten-minute job instead of a design debate.Multi-repo analysis
Cross-repo audits that gate on verification: map both codebases, report the real data layer, and stop if reality contradicts the assumption — before a line of the rewrite is written.
