Project details

Your Python script stopped working, throws an error, or just gives the wrong result — and you need it running again without the back-and-forth.

Here's how I work:
1. You send the script, the error message, and a sample of your real input.
2. I find the root cause (not a band-aid), fix it, and run it on your real input in a clean environment to confirm it actually works.
3. You get back the working script plus a short, plain-English note on what was wrong and what I changed — no jargon.

I build production AI agents and automation for a living, so debugging Python — scrapers, API scripts, data cleanup, automations — is daily work for me. I'd rather tell you "this one's bigger than it looks" up front than guess. Clear scope, fixed price, and I keep going until it runs.

About Daniel

Daniel K.Status: Offline
AI & Automation Engineer | AI Agents, Chatbots, Python & Scripts
Tenafly, United States - 12:17 am local time
I'm Daniel Kalina - an AI engineer and the founder of Let AI Build It, a studio that turns AI from a buzzword into systems that run in production
and pay for themselves.

Most "AI" work stops at a flashy demo. Mine starts where that ends. I design, build, deploy, and maintain real AI products on live infrastructure -
and I've shipped 30+ of them across real estate, finance, business analytics, and operations.

What I build:

AI AGENTS & AUTOMATION
Autonomous, multi-step agents that plan, take action, check their own work, and recover from errors. One example: a self-verifying code agent that
reproduces a customer's bug in an isolated sandbox, fixes it, and re-runs it to PROVE the fix works before anything ships - with a full job queue,
audit log, and human approval gates. I build agents that handle research, data wrangling, and repetitive workflows so people stop doing them by
hand.

REAL-TIME VOICE AI
Production phone agents that answer live calls, qualify and capture leads, book appointments, and hold a natural back-and-forth with sub-second
responses. Speech-to-text + LLM reasoning + natural text-to-speech, wired into real telephony, recordings, transcripts, and CRM hand-off.

DATA, ANALYTICS & VALUATION
This is where I love to work. I build tools that turn messy data into decision-ready insight - property and asset valuation, stock and SEC EDGAR
analysis, market and deal screening, and "ask your data in plain English" dashboards with a verification layer that catches wrong answers before
anyone acts on them. I currently lead technology for a real-estate data and analytics venture, so I understand valuation, deal analysis, and how
investors actually make decisions.

FULL-STACK & INTEGRATIONS
Underneath all of it is solid engineering: Python, JavaScript/Node, SQL, FastAPI/Flask, Docker, Linux, and clean deployments behind
Nginx/Cloudflare with monitoring. I integrate LLMs (Claude, OpenAI), Stripe payments (one-time and recurring ACH/card), telephony, and almost any
REST API into a product that holds up in the real world. I also come from a security background as an authorized penetration tester, so handling
sensitive financial and business data carefully is second nature.

HOW I WORK
- We scope the outcome first and agree a fixed price up front. I focus on project-based work so we're aligned on results, not hours - and I'm happy
to move to a monthly retainer for systems that need ongoing tuning.
- I build it and test it on real inputs until it genuinely works.
- I keep you updated in plain English the whole way - no jargon, no black box.
- If I can't deliver what we agreed, you don't pay.

I work best with founders, investors, real-estate and finance teams, and business owners who have a concrete problem - a manual process, a data
mess, a valuation or analytics need, or an AI idea they want built right the first time.

If that sounds like you, send me a note about what you're trying to do and I'll tell you honestly whether and how I can help.

I also design voice AI applications that can manage call interactions, qualify leads, and streamline appointment booking. My strong full-stack foundation allows me to maintain clear communication and deliver reliable, working software. If you're looking for innovative AI solutions that drive engagement and enhance operational workflows, I am here to help bring your vision to life. Let's collaborate to transform your ideas into impactful systems.
