Matthew Gagliardo

I build decentralized platforms — the encryption, the storage, the billing, and the apps on top. Currently Senior Engineering Manager at Ridgeline, and the sole engineer behind Muhkoo, a zero-knowledge application platform.

The platform

Muhkoo

A zero-knowledge application platform: authentication that never sees a password, end-to-end encrypted messaging and storage, a sharded database, serverless functions, AI agents, hosting, and metered billing. Built and operated solo.

Ridgeline

Senior Engineering Manager, Client Management

Leading the team behind Client Management — the entry point into Ridgeline's cloud platform for investment management, covering client and portfolio onboarding, the investor 360 view, and partner relationships. Own delivery across the full stack, and the culture around it: teaching, transparency, and modern practice — including AI-assisted workflows — without moving the quality bar.

Dec 2024 — Jul 2026

Cachengo

R&D Platform Lead

Architecting a platform-as-a-service for edge-based decentralized data centers. Built a data-ingestion path that scales with edge growth and has no single point of failure, and authored patents for a decentralized developer platform.

Jun 2022 — Nov 2024

384 Inc

VP of Engineering & Co-Founder

Took an end-to-end encryption product from idea to market and to government customers. Authored multiple patents and raised $3M to fund the build.

Dec 2021 — Jun 2022

Graphene Inc

Chief Technology Officer

Architected the core end-to-end encryption protocol, its APIs, and the SDKs customers built against.

Jan 2017 — Dec 2021

Twilio

Software Engineering Manager / Director

Led corporate IAM for GDPR, SOC 2, and Schrems II alongside service regionalization — data and API residency that mitigated $40M in annual fines. Designed early versions of the Flex API, now Programmable Contact Center, and supported the Paste 2 design system.

What I bring

Depth, not a keyword list

Platform architecture
Distributed and decentralized systems, edge compute, sharding and fan-out, and the unglamorous parts — quotas, metering, and billing — that decide whether a platform survives its own success.
Applied cryptography
End-to-end encryption, zero-knowledge authentication, forward-secret messaging, key derivation and recovery, PKI. Shipped as products people use, not as papers.
Engineering leadership
Building teams that teach each other. Hiring, mentoring, and setting a delivery cadence; translating tangled domain workflows into software people trust daily.
Compliance under pressure
GDPR, SOC 2, Schrems II, and data residency — designed into architecture rather than bolted on, at a scale where getting it wrong carried a nine-figure price.
