From MVP to Enterprise: Node.js, Python & Flutter

For founders and teams who need outcomes, not overhead: I design and build custom web applications, SaaS products, and cross‑platform Flutter apps. With Node.js & Python at the core, I deliver secure APIs, high‑performance backends, and scalable web application solutions engineered for growth.

I operate as your fractional CTO and development partner—combining full‑stack development consulting with pragmatic execution. From MVP development to legacy system modernization and software integration services, you get senior ownership without agency bottlenecks.

Core Expertise

Full-Stack Development
Business Strategy
System Architecture
Partnership Approach

Your goals are clear. The right web, SaaS, or mobile solution isn’t.

You have a business to run. Whether it’s custom web application development, custom SaaS, backend/API services, or a Flutter app—choosing the right stack, scope, and path to MVP can feel risky and slow.

Stuck on Tech Choices

Node.js or Python? Build or buy? What belongs in v1? One wrong choice can waste budget and delay launch.

Frustrated by Agency Handoffs and Delays

Outsourcing to big agencies often means layers, ticket queues, and slow decisions. You need direct access to a senior full‑stack developer who ships.

Burdened by the CTO Role

Wearing the CTO hat while running the business—scoping features, de‑risking architecture, integrations, and legacy modernization—steals focus from growth.

"Exactly why I operate as a fractional CTO and senior full‑stack partner—clear decisions, reliable delivery, and measurable outcomes."

Fractional CTO + Full‑Stack Delivery for Custom Web, SaaS & Flutter

Not a one‑off freelancer. A senior partner who owns outcomes: CTO as a Service, architecture reviews, and minimum viable product development for B2B and enterprise. Node.js & Python backends, secure custom API development, and scalable infrastructure that grows with you.

CTO‑Level Clarity & Ownership

Direct access to your builder and strategist—no layers. Clear roadmaps, de‑risked decisions, and business‑first trade‑offs.

Faster Decisions, Faster Launch

Ship faster with an agile, senior partner. Cut handoffs, unblock scope, and move from idea to MVP quickly.

Built for Scale & Security

Scalable web application solutions with robust security, observability, and performance across Node.js/Python backends, APIs, and cloud.

Hiring & Outsourcing FAQs: Cost, Timeline, Process

Clear answers for custom web application development, custom SaaS application development, backend/API development, and Flutter app development. Don't see yours? Let's discuss it.

Pricing depends on scope and complexity. After a free strategy call, you'll receive a clear, fixed‑price proposal within 24 hours—scope, milestones, timeline, and deliverables included. I support both fixed projects and ongoing retainers for CTO as a Service and full‑stack development consulting. No surprises—just predictable custom software development services.

Most MVPs ship in 3–8 weeks. Larger web/SaaS platforms typically take 8–16+ weeks depending on integrations and complexity. Flutter apps generally follow similar timelines. Legacy system modernization varies by codebase. You'll get a realistic timeline with your proposal and weekly progress updates.

After launch, you get a 30‑day warranty for fixes. Many clients continue on a monthly retainer for proactive maintenance, security, monitoring, and feature delivery—essentially CTO as a Service. This keeps your custom web app, SaaS, backend/APIs, or Flutter app secure and evolving with the business.

Direct access to me via Slack, WhatsApp, email, and scheduled video calls—no account managers. Weekly demos, transparent progress tracking, and rapid decisions so custom web/SaaS and backend/API work moves fast.
