START HERE
A clear path from idea to live product.
Most visitors arrive with a half-defined idea, an overloaded backend, or an AI feature that needs to be real. The first step is not a sales pitch; it is a practical scope, risk and delivery conversation.
AI workflow automation
Add production AI features such as document intelligence, RAG, semantic search, summaries and workflow automation with cost and privacy controls.
Legacy/internal tool modernization
Replace fragile spreadsheets, old backends or manual operations with maintainable internal tools, APIs and dashboards your team can own.

4 weeks
from scope to live SaaS
107
automated tests passing
9
AI workflows in production
0
known failing checks
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-optimized hamburger drawer UX, natural language audit explanations, streamlined navigation, and responsive design. All 6 phases complete.
What this proves
4
weeks to live SaaS
Scope, architecture, build, deployment and handover moved as one delivery system.
107
tests passing
Regression risk is controlled with an automated suite and CI gate, not manual hope.
9
AI workflows shipped
AI moved beyond demo mode into search, reports, audit explanations and live data workflows.
0
known failing checks
Security, auth, audit trail and deployment controls were treated as launch requirements.

02 · WHY WORK WITH ME
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
A client's previous developer shipped auth without password hashing — I found it during a handover audit. That stays with you. Now AES-128 encryption, bcrypt, JWT refresh rotation, TOTP 2FA and a full audit trail are the baseline on every project I ship. Not a billable extra, not an afterthought. You get the codebase I'd want protecting my own data.
Zero security shortcuts — ever
AI cuts your timeline, not your quality
I use Claude, Cursor and Copilot at every stage — but not for code I can't explain. AI handles the predictable parts: test scaffolding, boilerplate, documentation drafts. That frees me for the decisions that actually matter — architecture, edge cases, security tradeoffs. CitizenApp shipped 9 production AI features, 107 tests, multi-tenant RBAC and Stripe billing in a matter of weeks — not months.
9 AI features · 107 tests · multi-tenant · weeks not months
The test suite ships with the code
The CitizenApp test suite caught a migration bug before it reached a paying customer. That's the actual value — not a coverage number, but catching the failure that would have broken a workflow at 2am. Every project I hand over includes pytest, Vitest, and a CI gate that blocks broken deploys. The test suite is yours from day one.

03 · HOW I WORK
A repeatable process
with zero surprises.
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.
Typical timeline
01 · Discovery Days 1–3
02 · Build Weeks 1–3
03 · Harden Week 3–4
04 · Ship Week 4
Total ~4 weeks
01
Discovery
Days 1–3 📄 Written technical specArchitecture 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.
02
Build
Weeks 1–3 🔗 Live URL every FridayAI-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.
03
Harden
Week 3–4 ✅ Test report + CI gateComprehensive 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.
04
Ship
Week 4 🚀 Deployed · full handoverZero-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.

Fractional CIO · Full-Stack · AI Engineer · Ankara 🇹🇷
"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.
