I'm a full stack software developer with 10+ years of hands-on experience with Ruby on Rails and Javascript. I’ve worked across the spectrum: early startups, high-growth scale ups, and most recently, a large corporate product with a huge Rails monolith and even bigger DB. On the FE side I've worked with a range of libs and frameworks, starting with raw JS a long time ago all the way to Svelte.js more recently.

Have a look at my LI and if you think you're building something where I could help, let me know!

Ex-Google engineer, 10+ years in software, last 2+ focused fully on GenAI. I’m looking for consulting and hands-on work, not just giving advice.

I help teams integrate LLMs into real-world workflows. Comfortable working across the stack (Python, React), from quick prototypes to production systems.

Past work includes agentic workflows, eval pipelines, prompt frameworks, GPT-powered tools, and full-stack AI products.

I prefer working directly with stakeholders. Big fan of startups.

About Me:

I'm a full-stack developer with a focus on building entire products, not just features. Since 2018, I've been helping startups and founders turn ideas into reality. I'm comfortable owning the whole stack, from provisioning AWS resources to polishing the front-end.

One of my recent projects involved building a USMCA compliance tool from scratch. I took a manual, spreadsheet-heavy process and turned it into a web app that provides a go/no-go qualification in under a minute. The stack was Python on AWS Lambda, DynamoDB, and React.

I also enjoy working with a lighter-weight stack and recently built my own SaaS product (a time-tracker for freelancers) using Django, HTMX, and AlpineJS.

I'm looking for clients who need a reliable, senior-level engineer to build robust solutions to complex business problems.

Send me an email with your needs and I'll reply to schedule a quick 15 min call.

Remote: Yes

Technologies: TypeScript, React, Python/Django, AI/LLMs, ML workflows

Portfolio: https://ustunozgur.com

Email: ustun@ustunozgur.com

Freelance engineer available for early-stage startups. I specialize in building AI SaaS products from zero to production.

Recent work:

- Edge Delta: built an AI chatbot to manipulate their pipeline builder with natural language

- Runy: AI-driven property management platform

- Braid Health: integrated AI-assisted diagnostics into radiology workflows

- Previously: Toolio (retail SaaS), SellerCrowd (adtech marketplace)

What I offer:

- Rapid AI-powered MVP development (weeks, not months)

- LLM/chatbot/ML integration into SaaS

- Fractional CTO support (architecture + hands-on)

Looking for short- or medium-term freelance projects or ongoing fractional CTO work.

I'm a fractional CTO and hands-on product engineer with over 17 years of startup experience. I help non-technical founders turn ideas into reality - working products and teams that provide a solid foundation for profitability, fundraising, and growth.

I offer the following services:

1. Product design - design a product that users want, investors back, and engineers can actually build.

2. Product development - build a quality product quickly and start gathering feedback from customers and potential investors as early as possible.

3. Engineering management - hire, onboard, and lead a lean engineering team to accelerate product development and optimize cost.

4. Technical consulting - pick a tech stack and processes appropriate for the current stage without putting future growth at risk.

5. Project rescues - get your project back on track, understand why it went off the rails, and ensure it'll stay on the right track.

If that sounds like what you need then let's chat: contact@gregnavis.com

I've worked across many stacks, but prefer tried and true tech: React + TypeScript or Hotwire on the frontend; Ruby on Rails on the backend. I also have significant experience with Elixir (+ Phoenix) and Python (+ Flask).
