I've been building production systems for 15+ years - not POCs that gather dust. Freelance Tech Lead - I design it, I build it, I ship it.

Architecture & Tech Lead

Problem

Your IT is slowing you down. Tech debt piling up, infra costs through the roof, dev team running without a clear technical direction.

Solution

I run the audit, design the target architecture and lead the devs. Distributed, event-driven, cloud migration - the real stuff, not slide decks.

Results

-30% on infra costs, +15% operational performance. Battle-tested across 500+ retail locations.

Custom business platforms

Problem

Your business needs are too specific for any off-the-shelf SaaS. You need something custom that actually handles the load.

Solution

I build the whole thing end-to-end - back-office, APIs, frontend. Supply Chain, E-Health, HR: domains where I've already shipped.

Results

Production systems processing millions of transactions monthly. Real-time monitoring for 200+ users.

Applied AI & Data

Problem

You want AI that actually works in prod - not a demo that collects dust. Matching, prediction, automation - real use cases.

Solution

I plug AI straight into your business tools. LLMs, classical ML, data pipelines - no gimmicks, just measurable results.

Results

+40% accuracy on a job matching engine. -25% stockouts with ML prediction.
