Hi, I'm Justin.

Full‑stack engineer for scalable web products

I design and build performant backends, clean APIs, and robust web apps – pragmatic, test‑driven, and maintainable.

Start a project GitHub
  • Backend (Python) & APIs
  • Web development & e‑commerce
  • Automation & scraping
  • ML / Computer Vision (VGG16)

Tech stack & architecture

Frontend

  • Vanilla JS, semantic HTML, performant CSS
  • SSR/ISR when needed, progressive enhancement

Reasoning: simple, fast, minimal dependencies.

Backend

  • Python (FastAPI/Flask), REST, auth, background jobs
  • Background jobs (queues/workers) for resilience

Reasoning: clarity over magic; testability first.

Data

  • Relational DB (e.g. PostgreSQL), Redis caching
  • ETL & migrations

Reasoning: SQL for consistency & constraints; prefer Postgres.

DevOps/Cloud

  • CI/CD, containers, lightweight IaC
  • Observability (logs, metrics, tracing), alerts

Reasoning: fast deploys, measurable quality.

Services

Web development

Fast, accessible websites and web apps – SEO‑friendly and maintainable.

Backend (Python) & APIs

Robust Python backends, REST APIs, persistence, and integrations (e.g. FTP, external services).

Automation & scraping

Automated workflows, data collection, monitoring, and reporting – reliable and compliant.

E‑commerce & Data/ML

Shop integrations, inventory/price sync with ERP, payments/shipping, plus image/text processing incl. VGG16‑based similarity search.

Selected projects (anonymized)

Automated invoicing & management

Including FTP integration and price calculator

  • Invoice generation incl. sequential numbering and PDF export.
  • Parameter‑based price calculation; management of open items.
  • Automated FTP upload to a target system.

Inventory sync & order processing

Product/stock sync between shops and ERP

  • Keeps inventory, prices and variants in sync across shops/ERP.
  • Order import/export via API/CSV/FTP with status updates.
  • Resilient error handling (retry), monitoring and logging.

Image DB matching with VGG16

Similarity search across large image collections

  • Compare arbitrary images against a large database (top‑N matches).
  • Feature extraction with VGG16, efficient indexing and ranking.
  • Extendable with semantic filters and report generation.
Computer VisionVGG16Indexing

Web monitoring & evidence capture (anonymized)

Data collection, matching, and automated reports

  • Scrapers to archive and version website content and search results.
  • Database matching and notifications on hits.
  • Automated report generation for internal review processes.

Some projects are confidential; details and demos available on request.

About me

I build solutions that deliver real value: from performant web apps to automation and data matching. Pragmatic, test‑driven, and maintainable.

Skills

  • Backend development, REST APIs, databases
  • Frontend implementation, UI integration
  • Scraping, automation, ETL
  • Computer vision (feature extraction, similarity search)

How I work

  • Clear scope, fast prototypes, early feedback
  • Automated tests, CI/CD, measurable metrics
  • Transparent communication, short iterations

Process

1. Intro

Short call to clarify goals and scope. I provide an initial assessment.

2. Proposal

Outline of solution, scope, timeline, and budget – pragmatic and realistic.

3. Build

Iterative, test‑driven, and transparent – regular checkpoints.

4. Handover

Delivery, documentation, and optional follow‑up or ongoing support.
