01 · PROJECTS

Live in
production.

Not side projects. Not tutorials. Deployed, monitored, maintained — built on architecture that scales.

CASE STUDY ● LIVE IN PRODUCTION v5.0.4

CitizenApp

KVKK/GDPR-compliant citizen management SaaS · Vercel Edge + Render + Neon Postgres (Frankfurt)

Problem

Public-sector agencies needed a secure, auditable way to manage citizen records — with strict compliance from day one, not retrofitted later.

Challenge

Multi-department workflows, 3-tier access control, PII encryption, real-time audit logging, 2FA, and intuitive mobile UX — all in a maintainable SaaS that non-engineers can operate.

Solution

FastAPI + React 19 multi-tenant SaaS with Fernet AES-128 encryption, JWT refresh rotation, RBAC, TOTP 2FA, 30+ audit event types, and CI/CD. Claude powers 9 AI features: NL search, CSV mapping, anomaly detection, daily briefing, duplicate merge, NL reports, AI chat with live SQL, audit trail explanation, and credit metering. Stripe billing and Python name normalization.

Results

GDPR-aligned, verified architecture. 107 automated tests, zero failures. Production-ready with mobile-first hamburger drawer UX, natural language audit explanations, and streamlined navigation. All 6 phases complete: multi-tenancy, 9 Claude AI features, Stripe billing, data quality tools, audit trail, and responsive design.

SaaS & Web Apps

From validated MVP to production-grade product — deployed, monitored and maintainable from day one. Auth, RBAC, GDPR, encryption and CI/CD are default, not extras. You get a living codebase your team can own — not a disposable prototype.

✓ Multi-role auth · TOTP 2FA · JWT refresh rotation
✓ Fernet encryption at rest · GDPR-compliant data model
✓ Automated test suite · CI/CD gated deployments
✓ Full audit trail · Sentry monitoring · OpenAPI docs

FastAPI React 19 PostgreSQL JWT · 2FA Docker

Typical: 1–3 weeks

APIs & Backend Systems

High-performance REST APIs built for scale and maintainability. Security scanning, rate limiting and comprehensive test coverage are included by default — not billable extras. Every endpoint in OpenAPI. Every migration Alembic-tracked.

✓ OpenAPI docs · Pydantic v2 validation · typed schemas
✓ Redis caching · IP rate limiting · account lockout
✓ Alembic migrations · zero-downtime deploys
✓ pytest coverage · GitHub Actions CI/CD pipeline

AI Integration & LLM Features

Production-ready AI features for your product — same security and reliability as everything else I ship. No experimental APIs in production. No vendor lock-in without a documented exit plan. Cost controls, fallback handling and rate limits baked in from day one.

Document intelligence

Extract, classify and search PDFs, DOCX and image content at scale

RAG & semantic search

Vector embeddings + retrieval over your private data, with source citations

Intelligent chat

Context-aware assistants, streaming responses, conversation memory

Workflow automation

LLM-powered classification, summarisation and data extraction in your stack

Other developers write code.
I ship products.

vs. alternatives: Dev agency 3× the cost, 2× the time Junior freelancer security bolted on later No-code tools no security, no ownership ✓ Senior-quality, startup speed, full ownership

Security isn't an add-on

Most developers think about security at the end — if at all. Every project I deliver ships with Fernet AES-128 encryption, bcrypt hashing, JWT refresh rotation, TOTP 2FA, rate limiting and a full audit trail. Before you ask. Before launch. By default.

Zero security shortcuts — ever

AI makes your timeline shorter

I use Claude, Cursor and GitHub Copilot across every stage — architecture decisions, code generation, test writing, documentation. You don't pay for the time I spend fighting boilerplate. You get faster iterations, better coverage, and more bandwidth for the decisions that actually require deep thinking.

9 production AI features · ~3× faster delivery

Tests aren't afterthoughts

CitizenApp ships with 107 automated tests — zero failures. That's pytest on the backend, Vitest on the frontend, and a CI/CD gate that blocks broken deployments. Test coverage isn't a metric I chase at the end — it's a constraint I code against from day one. You get software you can actually maintain.

03 · PROCESS

How a project
actually works.

Predictable process. Weekly visibility. No surprises at launch. You see real progress every single week — not a "reveal" at the end of a long silence.

Discovery

Days 1–3

Architecture review, security model, data model, stack decision, timeline. I ask uncomfortable questions early — because they're cheaper at day 1 than at week 4. You get a written technical spec before a single line of code is written.

Build

Weeks 1–3

AI-accelerated development with daily commits and weekly demos. You see a working build every Friday — not screenshots, a live URL. Boilerplate gets handled fast; architecture and the decisions that matter stay with me.

Harden

Week 3–4

Comprehensive testing, security audit, performance profiling, dependency review. The CI/CD pipeline is set up and gated. Nothing ships until tests pass. Nothing deploys until I'd stake my name on it.

Ship

Week 4

Zero-downtime deployment, monitoring setup, full documentation, clean handover. You own the code, the repo, the infrastructure. No lock-in. No "maintenance only I can do." You leave with something your own team can take forward.

05 · ABOUT

Backend veteran.
AI-augmented
builder.

"The best developers in 2026 don't just write code — they architect solutions and use AI to ship them significantly faster."

After 10+ years of Python, PostgreSQL and Redis backend work, I moved into full-stack development and then AI-augmented engineering. I ship end-to-end products with modern React 19, TypeScript and Tailwind — with an architectural depth most frontend-first developers can't match.

AI tooling is embedded in how I work — not as autocomplete, but as a genuine force multiplier at every stage. Faster architecture validation. Faster test generation. Fewer bugs reaching review. More of my time on the decisions that actually matter to your business.

Ten years of backend work means I've already made the expensive mistakes: missing indexes that kill performance at 100k rows, auth flows that seemed fine until a breach, migrations that silently dropped columns in production. I don't repeat them. That institutional knowledge is what you're actually hiring.
