AI Development Services

AI development here means production systems handling real users, real data, and real edge cases, not a demo that only works with the perfect input. Chatbots, assistants, and retrieval systems are built with the same engineering discipline as the rest of the platform.

AI Chatbot Development

Chatbots trained on a business's actual data and actual tone, not a generic script with a few swapped-in variables, built to hand off to a human cleanly when a conversation needs one.

Custom AI Assistant Development

AI assistants scoped around a specific job: drafting emails, pulling records, summarizing calls, or whatever the repetitive task actually is. Built to plug into the tools a team already uses.

LLM Integration Services

Getting GPT, Gemini, or Claude working reliably inside an existing product is a different skill than calling an API once in a demo. Prompt design, fallback handling, and cost control are all part of doing it properly.

AI Knowledge Base (RAG) Development

Retrieval-augmented generation systems that answer from a business's actual documents, not the model's general training data, so answers stay grounded in what's true for that specific company.

Web & SaaS Development

From a first working MVP to a full multi-tenant SaaS platform, this is a team that has shipped ISO and SOC 2 certified software, not just prototypes. Every build gets a real architecture decision behind it: what needs to scale on day one and what can wait.

SaaS Product Development

End-to-end SaaS builds: multi-tenant architecture, subscription logic, admin dashboards, and the unglamorous plumbing that decides whether a platform holds up once real customers start using it.

MVP Development

A working MVP built to test a real hypothesis, not a pile of half-finished features. The goal is something users can actually try, so the next round of decisions comes from real feedback instead of guesses.

Custom Web Application Development

Web applications built around a specific workflow, not squeezed into an off-the-shelf tool that almost fits. If a process is unusual enough that no existing SaaS handles it cleanly, a custom web application is the alternative.

Mobile App Development

AngleBrackets builds native and cross-platform mobile apps for iOS and Android, backed by experienced engineers who deliver on real app stores, not internal demos. Whether the need is a consumer app, an internal tool for field teams, or an AI feature integrated within an existing product, the scope is built around what the app actually needs to do.

AI-Powered Mobile Applications

Mobile apps with AI built into the core experience, not a chatbot bolted onto a settings menu. Voice transcription, on-device recommendations, and automated content generation are already delivered inside real, published apps.

iOS & Android App Development

Native builds for both platforms, or one codebase that runs well on either, depending on what the project actually needs. App Store and Google Play submissions and platform-specific polish are part of the standard build.

React Native App Development

One React Native codebase covering iOS and Android without sacrificing performance or platform feel, a solid fit for startups that need to move fast across both stores without two separate native teams.

Voice AI Solutions

Voice AI that handles real phone calls, not a scripted demo recorded in a quiet room. Built on the same call-handling infrastructure used in production, with real fallback paths for when a caller needs a human.

AI Receptionist Solutions

An AI receptionist that answers calls, books appointments, and syncs straight to a real calendar and CRM, not just a voicemail with better manners, already tested against real inbound call volume.

AI Voice Agent Development

Voice agents built for a specific job, outbound follow-ups, appointment reminders, lead qualification, rather than a general-purpose assistant stretched thin across everything at once.

AI Call Automation & Booking

Inbound and outbound call automation that actually books the appointment instead of just collecting a callback request, connected directly to scheduling tools so the calendar updates itself.

Custom Software Development

Custom software for the parts of a business that off-the-shelf tools weren't built to handle. Enterprise systems, internal CRMs, booking platforms, and marketplaces are each scoped around the actual workflow, rather than the closest available template.

Enterprise Software Development

Internal systems built to handle real organizational complexity: multiple departments, permission levels, and legacy data that needs to migrate cleanly instead of getting left behind.

CRM Development

A CRM built around how a sales or service team actually works, not a generic pipeline with fields nobody uses. Automations get added where they save real time, not everywhere at once.

Booking & Scheduling Systems

Scheduling software that handles the actual constraints of a business, multiple staff, overlapping availability, and buffer times, instead of a basic calendar plugin stretched past what it was built for.

Marketplace Development

Two-sided marketplace platforms with the parts that are actually hard to get right: payments, trust and verification, and search that surfaces the right listings instead of just the newest ones.

Cloud & Backend Development

The backend work that decides whether a product holds up under real traffic: database design, service architecture, and cloud infrastructure built to scale before it has to, not after something breaks.

Backend Architecture & Database Design

Database schemas and service architecture designed around how the data actually gets used, not just how it looks in a first draft, since these are the decisions that are expensive to undo later.

Cloud Infrastructure

Infrastructure on AWS or GCP built to handle real load without turning into a surprise bill, right-sized from the start, with room to scale when the traffic actually shows up.

Microservices Development

Breaking a system into services where it actually helps, deployment speed, fault isolation, and team ownership, rather than microservices for their own sake on a product that didn't need them yet.

Automation & Integrations

Automation that removes a real bottleneck instead of adding another tool nobody opens. We build workflows, CRM integrations, and process automation around the specific manual step that's actually costing the team time.

Workflow Automation

Automating the repetitive steps between tools that currently rely on someone copying and pasting between them, built to run quietly in the background instead of adding another dashboard to check.

CRM Integration

Connecting a CRM to the other tools a team actually uses, so data stops living in three places at once and going stale in at least one of them.

Business Process Automation

Mapping an actual manual process, approvals, onboarding, reporting, and automating the parts that don't need a human making the same decision every single time.

CMS & Website Development

Websites built on the right CMS for the job, not the same stack applied to every client regardless of fit. Jamstack for speed and simple content updates, headless CMS when a team needs more structure, and WordPress when a client's team already knows it.

Jamstack Development

Fast, statically generated sites built on Next.js or Gatsby with a headless CMS behind them, giving a marketing or content team a way to update pages without a developer in the loop.

Headless CMS Development

A CMS is decoupled from the front end, so content can feed a website, a mobile app, or both from a single source instead of duplicating it across platforms.

Corporate Website Development

Websites built for companies that need to look established and load fast, without the bloated page-builder plugins that slow many corporate sites down.

Marketing Website Development

Landing pages and marketing sites built around conversion, not just aesthetics: clear structure, fast load times, and copy that actually gets read before someone clicks away.

UI/UX Design

Designers focus on how people actually use software under real conditions, rather than just how a mockup appears in a portfolio. Dashboards, mobile flows, and websites get designed around the task a user is trying to finish.

SaaS Dashboard Design

Dashboards designed to surface what a user actually needs to see first, not every metric the database happens to store, and complex data made scannable instead of just technically displayed.

Mobile App UI/UX Design

Mobile interfaces are designed around one-handed use, thumb reach, and the platform conventions users already expect, so the app doesn't feel like it's fighting the phone it's running on.

Website UI/UX Design

Website design should be based on how visitors actually scroll and scan a page, rather than using a template that is simply stretched to fit the brand colors. Structure comes before decoration.

DevOps & Cloud

The infrastructure work that happens after launch day: deployment pipelines, containerization, and cloud setup built so shipping an update doesn't require a manual checklist every single time.

AWS Cloud Deployment

Applications deployed on AWS with the actual services a project needs, ECS, RDS, CloudFront, and so on, rather than a generic setup that works but costs more than it should.

CI/CD Pipeline Setup

Automated build, test, and deploy pipelines ensure that a code change goes through a repeatable process, rather than relying on a manual deployment that someone has to remember every step of.

Docker Containerization

Applications packaged into containers that run the same way in development, staging, and production, so “it worked on my machine” stops being a real problem.

Payment & Commerce

Payment infrastructure must work correctly every time, because this area of the product is where mistakes cost real money. Gateway integrations and subscription billing handle edge cases up front, not after a customer complains.

Payment Gateway Integration

Stripe, PayPal, or another gateway wired into a product correctly the first time, handling failed payments, refunds, and currency edge cases instead of only the happy path shown in a demo.

Subscription Billing Systems

Recurring billing logic that handles upgrades, downgrades, proration, and failed renewals without a support ticket for every plan change a customer makes.

SEO Services

SEO built around how search actually works today, including how AI assistants and generative search surface answers, not just a keyword list from five years ago. Technical, local, and e-commerce SEO all get treated as different problems with different fixes.

AI SEO

Optimizing content so it gets cited by AI assistants and generative search results, not just ranked in a traditional blue-link list, a newer discipline that's already affecting where traffic comes from.

Local SEO

Getting a business found in local search and map results where customers are actually searching by neighborhood or city, not competing nationally against companies with much bigger budgets.

E-Commerce SEO

Product and category pages optimized to actually rank and convert, not just technically indexed. Structured data, page speed, and content all get treated as ranking factors, because they are.
