~/what-i-do.md

john_kleinad/what-i-do

The whole product. One person.

I'm a one-person product team — the same engineer who sketches the wireframe pushes to prod. Fewer meetings, faster iterations, direct access to the person making decisions.

01 · REQUIREMENTS

We define what to build

45-min discovery call to align on goal, users, scope, and success metrics. You leave with a written brief and a fixed quote — no strings attached.

02 · DESIGN

We design the screens

Wireframes first, then hi-fi Figma. We iterate until you approve. Mobile-first and accessibility-aware. Zero surprises once development starts.

03 · DEVELOPMENT

I build the product

Next.js, React Native, Node, GraphQL, PostgreSQL. Typed and tested, with weekly demos — you watch the product take shape, not just the invoices.

04 · PRODUCTION

I launch and maintain

AWS infrastructure, App Store + Play submission, observability, and post-launch fixes. Maintenance and 24/7 support included from day one.

~/services.md

john_kleinad/services

Five services. Quoted after a 45-min call.

Starting prices in USD. Every service includes maintenance, 24/7 support, and clean infrastructure — not just code.

~/services/landing.tsx

01 · LANDING PAGE / MARKETING SITE

A site that turns visitors into paying customers — live in days, not months.

Who it's for

For founders launching a product or campaign who need to be online fast and start collecting real customers. Built from scratch — no templates, no website builders.

What's included (depending on your needs)

✓Analytics setup — You'll see real visitor numbers.
✓Hosting + your domain — Deployed and live, with your custom domain wired up.
✓Sales-driven copy — Writing that actually converts.
✓Maintenance & 24/7 support — Direct line to me — no tickets, no middlemen, no telephone game.

~/services/webapp.tsx

02 · WEB APP / SAAS DASHBOARD

A real product your team and customers can rely on — not a no-code patch.

Who it's for

Admin panels, client dashboards, role-based access, real-time data. Scalable, and 100% yours.

~/services/mobile.tsx

03 · MOBILE APP (IOS + ANDROID)

One codebase, both app stores. Native-feeling apps at half the cost of building twice.

Who it's for

For products that need to live on phones — faster, cheaper, and easier to maintain than going fully native.

What's included (depending on your needs)

✓iOS + Android — From one React Native + Expo codebase.
✓Auth + push + deep links — Full lifecycle support.
✓Backend included — AWS Amplify or Node.js — your choice.
✓Store submission — App Store + Google Play — I handle it.

~/services/aws.tsx

04 · AWS INFRASTRUCTURE / CLOUD SETUP

Cloud that won't blow up your bill or crash in production.

Who it's for

Set up by an AWS Community Builder — fewer surprises, smarter costs, infrastructure you actually own.

What's included (depending on your needs)

✓Serverless architecture — Lambda + API Gateway.
✓Auth with Cognito — Managed user pools + identity.
✓Storage on S3 — Files, assets, backups.
✓Database setup — DynamoDB or RDS — your scale, your choice.
✓Cost review — Identify and trim unnecessary spend.
✓Observability dashboards — CloudWatch + metrics you'll actually use.
✓Maintenance & 24/7 support — Direct line to me — no tickets, no middlemen, no telephone game.
✓Clean infra-as-code — Reproducible, version-controlled, yours.

~/services/ai.tsx

05 · AI INTEGRATION / AGENTS + BEDROCK

AI that moves the needle on your business — not a demo that gathers dust.

Who it's for

Agents that close deals, chatbots that handle support, pipelines that turn documents into decisions. Enterprise models, your data stays yours.

What's included (depending on your needs)

✓AWS Bedrock setup — A wide catalog of language models.
✓Chatbot or AI agent — Conversational UI wired to your business logic.
✓Data pipelines with AI — Document analysis, summarization, classification at scale.
✓RAG / knowledge base — Your data, retrievable by the model — answers grounded in your truth.
✓Guardrails + cost controls — Token budgets, content filters, observability dashboards.
✓Maintenance & 24/7 support — Direct line to me — no tickets, no middlemen, no telephone game.
