1:1 and group chat with delivery receipts, media, and moderation—real-time infra that scales without losing messages when the network blinks.

Chat that feels instant and trustworthy—sync, search, and safety at the core

We implement message sync with offline outboxes, idempotent sends, and conflict rules for edits. E2E encryption is optional with explicit product tradeoffs documented for your team—not a checkbox we pretend is free. Backpressure, rate limits, and spam controls protect your infra; reporting and blocks protect your community at human scale.

01 // THE MANDATE

1:1 and group chat with delivery receipts, media, and moderation—real-time infra that scales without losing messages when the network blinks.

We implement message sync with offline outboxes, idempotent sends, and conflict rules for edits. E2E encryption is optional with explicit product tradeoffs documented for your team—not a checkbox we pretend is free.

Backpressure, rate limits, and spam controls protect your infra; reporting and blocks protect your community at human scale.

02 // ENGINEERING

Development process

Structured phases—from discovery to launch—with clear ownership and handoff points.

Product & threat model (weeks 1–2)

We clarify E2E vs transport encryption, data residency, and export obligations. MVP feature set and abuse tolerance defined.

Core messaging (weeks 2–10)

Send, receive, history, devices; mobile-first with web companion.

Realtime hardening (weeks 8–14)

Reconnect storms, fan-out costs, load tests; push notification reliability.

Safety & compliance (weeks 10–16)

Reporting, blocks, rate limits; admin tools; audit logs for enterprise pilots.

Launch (weeks 16–17)

App review readiness; support playbooks; on-call runbooks for message pipeline incidents.

Operate (ongoing)

Spam pattern updates; OS push token lifecycle; cost monitoring on realtime fleet.

03 // CAPABILITIES

Core Capability Matrix

The building blocks of your solution

Conversations

DMs, groups, roles, invites, leave/rejoin rules.

Messages

text, images, files, voice notes; upload virus scanning hooks.

Realtime

WebSockets with reconnect; push notifications; typing indicators.

Delivery

sent/delivered/read; device sync across mobile and web.

Search

message and people search with permissions and retention limits.

Moderation

report flows, admin review, legal hold exports (process-driven).

Compliance

retention policies; export for regulated industries when scoped.

Bots & integrations

webhooks, slash commands, OAuth for third-party tools.

Analytics

MAU, messages/day, report rate, notification delivery success.

Security

MFA, session management, device revocation, abuse detection.

04 // DELIVERY LIFECYCLE

The strategic roadmap

Milestones and checkpoints—each phase has a clear outcome before the next begins.

Milestone 01Delivery

Weeks 1–2: Scope, security review kickoff, pilot users.

Milestone 02Delivery

Weeks 3–8: Alpha messaging daily-driver ready.

Milestone 03Delivery

Weeks 7–12: Beta scale; groups; media polish.

Milestone 04Delivery

Weeks 11–16: Production criteria; enterprise pilot if in scope.

Milestone 05Delivery

Ongoing: Search v2; bots; regional hosting.

05 // PRODUCT SCOPING

Choosing your path

Two engagement models—start lean and iterate, or commit to a full platform build from day one.

MVP

Speed & essentialism

Phase 1
MVP: DMs, multi-device sync, media, push, search recent, reports/blocks. Excludes E2E, large groups at scale, and federation. Validates retention before infra-heavy features.
Recommended

Full product

Enterprise maturity

All-in
Full messenger: E2E option, large communities, moderation at scale, compliance exports, and SLA-backed enterprise hosting.

06 // PARTNERSHIP

Why work together

A single accountable partner across strategy, build, and go-live—not a revolving door of vendors.

John Hambardzumian
Direct collaboration

End-to-end ownership: discovery, architecture, implementation, and launch—with clear communication and production-grade engineering.

  • Discovery & alignment
  • Systems that scale
  • Implementation depth
  • Clear comms

07 // CLARITY

Frequently asked

We can bridge standards when interoperability matters; otherwise custom for UX speed—tradeoffs documented.
