If you need to ship a custom web application, automate internal business processes, or build an AI-powered SaaS product without the overhead of an agency or the risk of inexperienced freelancers, I can help.
I am Ekky Armandi, a full stack developer with 5+ years of experience shipping 100+ client projects across web applications, internal tools, and backend platforms. I work directly with founders, product owners, and engineering leaders who need a reliable technical partner to execute quickly and cleanly.
Short answer: Fixed-scope engagements typically range from $2,000 to $15,000+ depending on scope and complexity. Focused MVPs ship in 2 to 4 weeks; multi-module SaaS products land in 6 to 10 weeks. If you are validating an early idea, start with my MVP development services.
What I Build as a Full Stack Developer
I take products from concept and architecture through frontend UI, backend API design, database modeling, and production deployment:
| Product Category | Common Build Scopes |
|---|---|
| SaaS & Web Applications | Multi-tenant web apps, auth, billing (Stripe/Paddle), role permissions, user dashboards |
| Internal Business Tools | Custom admin panels, spreadsheet replacements, approval flows, operational tools |
| AI System Integration | LLM pipelines, RAG implementations, custom MCP servers, automated data processing |
| API Backends & Infrastructure | REST & GraphQL APIs, database architecture, background jobs, webhooks, third-party integrations |
| MVP Product Sprints | Rapid 0-to-1 builds focused on a single primary user workflow for fast market validation |
Why Hire a Solo Developer Partner?
Building software often breaks down into two bad choices: paying bloated agency markups for account management, or managing junior freelancers who require constant oversight. Hiring a solo full stack developer offers a better middle path:
| Dimension | Development Agency | Freelance Marketplace | Solo Developer |
|---|---|---|---|
| Communication | Account managers & PMs | Variable / fragmented | Direct with the engineer |
| Price Model | $30K–$150K+ (high overhead) | Hourly / unpredictable | Fixed-scope, fixed-price |
| Delivery Velocity | 3 to 6 months | Variable quality & delays | 2 to 8 weeks (AI-assisted) |
| Code Architecture | Delegated to juniors | Inconsistent standards | Experienced architecture & clean maintainability |
Modern Tech Stack & Architecture
I pick modern, maintainable stacks that scale cleanly without technical debt:
- Frontend: React, Next.js, Astro, TypeScript, TailwindCSS
- Backend: Python (FastAPI, Django), Node.js, Go
- Database & Caching: PostgreSQL, Redis, Supabase
- AI & Automation: OpenAI API, Claude API, FastMCP, n8n, Selectolax
- Deployment & Cloud: Vercel, Railway, Render, AWS

How the Hiring & Scoping Process Works
- Initial Fit Check: Send an email or book a 30-minute discovery call to share your project idea, current progress, and target timeline.
- Written Scope & Fixed Quote: Within 1 to 2 days, I provide a detailed written proposal outlining exact feature deliverables, milestone schedule, and fixed pricing. If you need dedicated scoping workshops first, see my Scope & Build Proposal.
- Iterative Development: We kick off development with regular progress demos and async communication. You see working software early and often.
- Deployment & Handover: The application is deployed to your cloud environment, complete with repository access, database documentation, and an operational walkthrough.
Frequently Asked Questions
How fast can you start and ship?
Kickoff happens within 3 to 5 business days after locking scope. Focused MVPs and internal tools ship in 2 to 4 weeks; multi-module web applications typically take 6 to 10 weeks.
Do I own 100% of the source code and IP?
Yes. All code, database schemas, and infrastructure configurations belong entirely to you from day one. Repositories are transferred directly to your organization upon project completion.
How do we communicate during the development process?
Directly with me. No account managers or junior intermediaries. Communication happens via async updates on Slack, email, or regular video check-ins depending on your preference.
What is your timezone and availability?
I am based in Yogyakarta, Indonesia (GMT+7) and maintain flexible overlap with client teams in the US, Europe, Australia, and Asia-Pacific.
What if I need ongoing support after launch?
Every fixed-scope build includes post-launch bug support. For continuous feature development, I offer ongoing retainer options or milestone-based scoping for new releases.
