AI · every day

I build with AI every day.

Not hype, not a demo reel — a power tool I reach for every day. It writes code beside me, and it ships as real features inside the products I build. Here is exactly how, where, and the rules I keep it on.

How I use it

Four ways AI earns its place

Same tool, four very different jobs — from writing code beside me to features your users actually touch.

As a pair engineer

Claude Code sits in my terminal as a second senior engineer — it reads the whole repo, writes to my conventions, and never tires of the boring parts.

What it does

Scaffolds features, refactors, and framework migrations
Writes tests and reproduces bugs from a stack trace
Reviews diffs and explains unfamiliar code
Automates the repetitive — codemods, config, glue

What I get

Days instead of weeks on mechanical work
More time on architecture and the hard calls

AI inside the product

The AI users actually touch — search that understands meaning, assistants that answer from your data, calls turned into text and scored.

What I build

RAG & semantic search over your content
LLM features: assistants, scoring, parsing, extraction
Speech-to-text with speaker separation
Grounding checks so answers stay backed by sources

What you get

Features that feel smart, not gimmicky
AI that does a job — measurable, not a demo

Content & media, faster

AI clears the blank page. Copy in three languages, social images, video — all produced inside the same visual system, not off-brand slop.

What it does

Multilingual copy & SEO (EN / ES / UK)
OG images and brand visuals generated to spec
Showreels and short video from a script
This very page — drafted, then hand-finished

What I get

A blank page is never the bottleneck
On-brand output, produced in hours

Automation of the boring

The repetitive back-office work that used to eat hours — handed to small, reliable AI jobs that run themselves.

What I automate

Ad-copy generation and bid rules (Google Ads)
Lead routing to Telegram / WhatsApp / email
Internal tooling and one-off data jobs
A team AI Hub so wins get reused, not rebuilt

What you get

Hours back every week
Fewer manual, error-prone steps

In production

AI I have actually shipped

Not slideware — real AI features running in production today. Follow any of them to the code or the live build.

Speech + scoring

CallLens

Sales calls turned into coaching — speaker-diarized transcription, an LLM scorecard with quoted evidence, and every call semantically searchable.

Hybrid RAG

Polylog

A multi-agent chatbot SaaS with hybrid RAG (BM25 + dense + RRF) and a grounding verifier that blocks ungrounded answers.

How I keep it honest

AI is powerful and confidently wrong in equal measure. These are the rules that keep it useful in production.

Human in the loop

AI writes the draft; I read every line before it ships. I own the decision, always.

Outcomes, not demos

If it doesn’t remove a real bottleneck or move a number, it doesn’t ship. Cool is not a reason.

Ground everything

Answers stay tied to sources. A grounding check beats a confident hallucination every time.

The win is often deleting AI

Sometimes a static page or a simple rule beats a model. Killing a feature is a valid result.

Own the data, pin the models

Self-hosted where it matters, exact model versions pinned — no silent drift in production.

Fast to try, ruthless to cut

Prototype in a day, measure honestly, keep only what earns its place.

The stack

What I reach for

The models, retrieval, and plumbing behind the work above — chosen for production, not for a demo.
