What We Build

We specialize in three interconnected disciplines — because your codebase, your cloud, and your CRM need to speak the same language.

TypeScript Application Development

We build full-stack TypeScript applications from Lambda functions to React frontends — TDD-first, pair-programmed, and designed to be owned by your team.

#TypeScript#NextJS#NestJS#Lambda#TDD
AWS Serverless Architecture

We design and build event-driven AWS infrastructure using Lambda, SQS, SNS, and EventBridge — with CDK infrastructure-as-code and full observability baked in.

#Lambda#SQS#SNS#CDK#EventBridge
HubSpot Implementation

We implement HubSpot from the data model up — API integrations, webhook pipelines, custom properties, CMS themes, email templates, and workflow automation that connects your product to your revenue operations.

Why SiteIT

We Go Deep, Not Wide

We're not a generalist shop. We go deep on three problems — and we've seen enough of them to know what breaks.

01

TypeScript-first, not TypeScript-capable

We don't bolt TS onto a Java shop. TypeScript is our primary language across frontend, backend, and cloud infrastructure — so your codebase speaks one language end to end.

02

Serverless architecture, not just serverless hosting

Lambda as application design from day one — not lift-and-shift. We architect event-driven systems with SQS, SNS, and EventBridge baked in from the first commit.

03

HubSpot configured for your data model

We rebuild the object schema before touching a workflow. Not HubSpot's defaults — yours. API integrations, custom properties, and pipeline automation that actually reflects your business.

04

Bespoke means you own the code

No platform lock-in. Your engineers inherit clean, tested TypeScript they can extend without us. We build for handoff from day one.

Engagement Models

We Work the Way You Need

Most agencies offer one model. We offer the one that fits your team — or the one that replaces one.

Full Delivery

Build For You

SiteIT owns full delivery — architecture, development, testing, deployment. You provide the requirements and product direction; we provide the engineering.

We take full ownership of delivery — from architecture decisions to production deployment. You stay in the loop without being in the weeds.

How We Build

From brief to production — five phases, test-first, AI-assisted, and built on TypeScript and AWS.

01

Discovery Phase

TypeScript AuditAWS AssessmentHubSpot Audit

Every engagement begins with a structured technical discovery. For TypeScript projects, we review existing codebases or define a clean architecture from scratch — assessing type coverage, test strategy, and module boundaries. For AWS work, we map the event-driven requirements against Lambda, SQS, SNS, and EventBridge to design the infrastructure topology before a line of CDK is written. For HubSpot implementations, we audit the existing CRM data model — object hierarchies, lifecycle stages, pipeline stages — and document what needs to be redesigned before any workflow automation is built. Discovery ends with a written architecture brief that both teams have verified.

02

Planning Phase

CDK IaCTypeScript InterfacesHubSpot Data Model

Planning translates the architecture brief into a sprint-level roadmap. TypeScript API contracts and interface definitions are written before any implementation begins — so both the frontend and backend teams have an agreed-upon shape for the data. AWS infrastructure stacks are scoped as CDK constructs, versioned from day one, and reviewed before provisioning. HubSpot custom object schemas, property groups, and pipeline configurations are designed in full before any portal changes are made. Milestones are set around deployable increments — every sprint ships something observable.

03

Build Phase

TypeScriptTDDClaude CodeAWS LambdaJest / Vitest

Build is where the architecture becomes code. We develop in TypeScript strict mode throughout — no implicit any, no escape hatches. Tests are written before implementation (Test-Driven Development): a failing test defines the contract, passing the test is the definition of done. Claude Code is an active pair partner in this phase — not autocomplete. AI assists with architecture review, implementation generation, and code quality feedback in real time, accelerating delivery without compromising coverage. Lambda handlers are built as stateless, event-driven units. HubSpot private apps and API integrations are coded and version-controlled — not configured in the portal UI.

04

Analysis & Iteration

CloudWatchX-RayHubSpot SandboxIntegration Tests

After each sprint increment, we validate the build against both automated and real-world conditions. Integration tests run against AWS services in a staging environment — not mocks. CloudWatch structured logging and X-Ray tracing are configured as part of deployment, not added as an afterthought. HubSpot changes are validated in a sandbox portal before touching production. TypeScript strict compilation and automated test coverage gates run in CI on every push. Stakeholder demos close each sprint cycle — feedback is incorporated in the following planning phase, not deferred to a release.

05

Continuous Improvement

X-Ray TracingHubSpot AnalyticsRetainerTypeScript

Post-deployment, we stay in the loop. AWS CloudWatch dashboards and X-Ray service maps give us live observability into Lambda invocation patterns, error rates, and SQS queue depths — so we catch performance gaps before they become incidents. HubSpot reporting surfaces CRM data quality, workflow enrollment rates, and lifecycle stage velocity. We run a TypeScript version upgrade cadence as the ecosystem evolves. For clients on a retainer, SiteIT engineers remain available for new feature development, infrastructure scaling decisions, and HubSpot process improvements. The relationship doesn't end at handoff.
