What we build
Four ways KeenCraft saves you money while shipping better software
Every service below is backed by a live, production system, not a slide deck.
Custom Software & Full-Stack Development
Web apps, dashboards, backends, and APIs built on a production-grade stack, not a template.
AI Voice Agents & Conversational AI
Inbound and outbound voice agents that answer calls, book appointments, and follow up 24/7, without a call center.
Automation & CRM / API Integrations
Connect the tools you already use so work stops falling through the cracks between systems.
Data & Backend Architecture
Caching, pipelines, and analytics-ready infrastructure that stays fast and correct as you scale.
How it works
A process built for one thing: no surprises
Four steps, from first call to launch. You always know what's happening, what it costs, and when it ships.
Free Strategy Call
30 minutes
We talk through what you're trying to build or fix, what it's costing you today, and whether KeenCraft is the right fit. No sales pitch, no pressure. If it's not a fit, I'll tell you.
Fixed-Scope Proposal
2 to 5 business days
You get a written Statement of Work with milestones, deliverables, and a fixed price, the same structure used on an 11-milestone SOW for an active FinTech client. You know the total cost before any code is written.
Build in QA-Gated Milestones
Varies by scope
Work ships in stages. Each milestone is tested before it's marked done and before payment is released, so you're never funding unfinished work or discovering problems after the invoice.
Launch & Support
Ongoing
You launch with a system you understand: documented architecture, not a black box. Ongoing support and iteration continue on the same transparent, milestone basis.
Proof, not promises
Live platforms and client deliveries, not portfolio filler
A look at 10+ live platforms and client deliveries. Every claim traces back to a real, shipped system.

Read the detailsThe problem
Most software spend doesn't fail on skill. It fails on structure.
Before you write another check to an agency, it's worth naming what's actually costing you, because the fix is usually cheaper than the problem.
Missed calls are missed revenue
Every call that goes to voicemail is a customer who books with the next business that actually answers. Staffing a phone line around the clock isn't cheap, or realistic, for most businesses.
Agencies sell you a team, then hand you off
You sign with a senior team on the sales call. Then a project manager hands your build to a junior dev you've never met, billing hours while they figure it out.
Hourly billing punishes you for asking
Scope creep isn't an accident in an hourly model. It's the business model. The slower the build, the bigger the invoice.
Disconnected tools quietly cost you
Every manual step between your CRM, your calendar, and your inbox is a place where leads go cold and staff time gets wasted.
Why it costs less, not more
The agency markup you're used to paying for isn't here
This isn't a discount on quality. It's the removal of the layers that don't add value to your build.

AI Voice Agent for a SaaS Product
AI Voice Engine · LiveKit
“Highly recommend Jareer for building our AI voice engine. He made strong, hands-on contributions to our LiveKit-based AI voice agent, including implementing key logic such as custom functions and knowledge-base integration. He also quickly identified and resolved several critical issues that were impacting system stability. Jareer understands real-time voice systems and AI workflows well, works effectively within an existing production codebase, and communicates clearly throughout the process. He's reliable, proactive, and focused on delivering working solutions, not just code. The voice agent is now in a solid, stable state, and we would confidently work with Jareer again on future development or scaling efforts.”
Python Developer: OpenAI, ElevenLabs, Deepgram & Azure Redis
Voice AI Stack · Long-Term
“Jareer is an exceptional talent. It is rare to find a developer who not only possesses deep expertise in Python and full-stack development but also truly understands the nuances of complex AI integrations. He seamlessly orchestrated a difficult stack for us combining LiveKit, Twilio, OpenAI, ElevenLabs, Cartesia, Hume AI, and Deepgram into a cohesive, production-ready solution. Beyond just writing code, Jareer is a proactive problem solver who delivers clean, scalable architecture.”

14 min readThe production stack behind every build
Trust & security
Your data, your users, and your reputation are handled like they matter
Security isn't a checkbox added at the end. It's part of how every system gets architected.
HIPAA-conscious builds
Healthcare infrastructure (as delivered for OptimateMD.health) built with data-handling standards in mind from the architecture stage, not bolted on after launch.
Platform-verified integrations
OAuth integrations taken through official verification processes (Google Ads API, as delivered on a live trades CRM), meeting the platform owner's own security bar, not just 'it works.'
Hardened site infrastructure
This site itself ships with strict security headers (CSP, HSTS, frame protection), validated and sanitized form input, and no secrets exposed to the browser.
Documented, auditable architecture
Every engagement ships with technical documentation: architecture overviews and API references, so your team is never dependent on one person's memory.
