Real-time bidding architecture: bidders call API Gateway and a bid Lambda that writes to DynamoDB with a conditional transaction. DynamoDB Streams feed EventBridge, which fans out to an SQS queue for notifications, Firehose for an S3 bid history queried by Athena, and a publisher Lambda that pushes live updates through IoT Core.BidderWeb · MobileAPI GatewayREST · AuthLambdaPlace bidEventBridgeBidPlacedDynamoDBStreams → PipesSQSRetry · DLQFirehoseBatch to S3LambdaLive publisherNotifierOutbid alertsS3 + AthenaBid historyIoT CoreMQTT → browsers

Services

Cloud-native engineering, end to end.

We specialize in systems that need to be reliable, scalable and cost-efficient from day one, and stay that way as you grow.

Serverless Applications

Production APIs and back ends on Lambda, API Gateway and DynamoDB, defined end to end as infrastructure as code.

Lambda · API Gateway · DynamoDB · AWS CDK

Event-Driven Architecture

Decoupled services that fan out with EventBridge, absorb spikes with SQS, recover with dead-letter queues, and push real-time updates to the browser.

EventBridge · SQS / SNS · IoT Core · WebSockets

AI Search & RAG

Natural-language search and retrieval-augmented generation over your content, built serverless so you pay for queries, not idle servers.

RAG · LLM pipelines · Vector search · Lambda

Cloud Migration & Kubernetes

Move on-prem workloads to AWS or Google Cloud with containers, Helm and Terraform, plus isolated environments for every feature branch.

Terraform · GKE / EKS · Helm · Vault

Data Pipelines & Analytics

Event data lakes you can query with SQL, streaming pipelines into BigQuery, and dashboards your business actually uses.

S3 + Athena · Glue · Pub/Sub · BigQuery

Payments & Integrations

Checkout, subscriptions and multi-provider payments, with third-party APIs wrapped behind clean, testable adapter layers.

Stripe · Adyen · PayPal · Twilio

Architecture & Technical Leadership

Well-Architected reviews, technical roadmaps, and fractional principal-level leadership for your engineering team.

Reference architectures

See how we think.

The patterns we start from, with the design decisions and trade-offs behind them.

All architectures

Lambda · DynamoDB Streams · EventBridge · SQS

Real-time bidding on serverless

Live auctions with strict bidding rules, instant updates to every bidder, and a full audit trail, without a single always-on server.

Read the architecture

Cognito · API Gateway · Lambda · STS

Multi-tenant data isolation

Serve many customers from one platform while guaranteeing that no tenant can read another's data, enforced by IAM and the database rather than by application code alone.

Read the architecture

EventBridge · Firehose · S3 · Glue Data Catalog

Event data lake on a budget

Turn the events your platform already emits into SQL-queryable history for reporting and audits, paying mainly for storage and the queries you run.

How we work

From whiteboard to production.

A clear, low-risk path with a working system in a real cloud environment early, not at the end.

  1. 01

    Discover

    We map your goals, constraints, traffic and current architecture, and identify the highest-risk unknowns early.

  2. 02

    Architect

    You get architecture diagrams, a data model, a cost estimate and a delivery plan before any code is written.

  3. 03

    Build

    Short iterations with working software in a real cloud environment, automated tests and a CI/CD pipeline from the first sprint.

  4. 04

    Launch & hand off

    Monitoring, alerting, runbooks and knowledge transfer, with ongoing support available if you want it.

Why Z Web Services

Senior engineering, without the agency layers.

We're a small, principal-level team with over 45 years of combined experience building enterprise software. You work directly with the people designing and building your system.

The architect writes the code
The senior engineers who design your system are the ones who build it. No hand-off to a junior bench.
Infrastructure as code from day one
Every environment is defined in CDK or Terraform and deployed by CI/CD, so it is reproducible, reviewable and disposable.
Cost-aware by design
Pay-per-use services and event-driven patterns mean your platform scales down as gracefully as it scales up.
Built to hand over
Tests, pipelines, observability and documentation are part of the deliverable. Your team owns what we build.

The team

The people you'll actually work with.
