I build the parts
that have to actually work.

Backend systems, automation pipelines, document AI, API integrations and recovery of difficult legacy projects — from technical audit to deployment and operational handoff.

Six cases across automation, AI, API integration and system recovery.

Each case focuses on the engineering problem, the decisions made and the delivered result — not just a list of technologies.

Capabilities
01

Backend & APIs

FastAPI, REST, PostgreSQL, SQLAlchemy, Redis, asynchronous services, migrations and integration boundaries.

02

Automation

Telegram, external APIs, background processing, retries, scheduling, synchronization, logging and operational handoff.

03

Document AI

Text extraction, OCR/vision fallback, structured extraction, classification, validation and multi-modal pipelines.

04

Recovery & Audits

Legacy codebases, build environments, production failures, deployment paths, root-cause analysis and stabilization plans.

How I work

Audit first when the real problem is unclear.

I am most useful on projects where the difficult part is not writing one more endpoint — it is understanding where the system actually fails, choosing a maintainable boundary and getting the whole path to work under real conditions.

That can mean tracing a broken legacy mobile build, validating an OAuth approval path, making a data pipeline resilient to external failures or separating environment problems from business-logic defects.
