Project details
🤝 Please read the terms below carefully to avoid misunderstandings and to ensure we meet the deadlines and respect our time.
WHEN THIS SERVICE IS RIGHT FOR YOU
🌟 This service is perfect for HTML to PDF generation using tools like wicked_pdf or wkhtmltopdf in Ruby on Rails
⚠️ Requires an existing single Ruby method as the data source (e.g., Invoice.find(invoice_id))
PROPOSE A CONTRACT INSTEAD IF
Your project requires:
💾 Data preparation or collection
📚 Multiple charts or combining data sources
✍️ Handcrafted PDFs from scratch (e.g., using prawn)
UNIFORM DATA STRUCTURE
If you need PDF for invoices and report, then you need to order this service twice, because it's twice a work.
If you need both the "monthly" and "daily report," they most likely use the same data structure, and this service covers that case.

🔵 Tier 2
Advanced styling:
• page header, clickable links, text markup and transformation, table styling

• addon styling
🟣 Tier 3

Diagnose and optimize Railway server for n8n
Ivan was phenomenal to work with. He jumped in immediately, diagnosed my n8n / PostgreSQL storage issue, tuned pruning and vacuum settings, and drafted a clear optimization plan that cut both disk usage and monthly costs. Communication was fast and detailed, and he patiently explained each change so I could learn from it. Delivered exactly what I needed, ahead of schedule, and went the extra mile. Highly recommended!

About Ivan
Senior Full-Stack & DevOps Engineer | Stack-Agnostic | 12 Years of Exp

Job Success
Tbilisi, Georgia - 8:13 am local time
Rather than being a traditional "Full-Stack" developer who is strong in one area and weak in others, I bring three equally strong, deeply practiced specializations to every project: Backend Engineering, Frontend Architecture, and DevOps/System Administration.
---
💼 HOW I WORK (THE AI ADVANTAGE)
I am on the cutting edge of AI-assisted software development. I don't do "vibe coding"; I practice rigorous Human-In-The-Loop (HITL) engineering.
By deeply integrating modern AI tools into my daily workflow (for code generation, complex refactoring, and code review), I achieve a massive boost in delivery speed and code quality. This allows me to build complex systems faster than a traditional developer, while maintaining strict architectural control and test coverage.
---
1. STACK AGNOSTIC & THE PRR PREFERENCE
I am fundamentally a stack-agnostic engineer. I can jump into and efficiently maintain JS/TS stacks (Next.js, React, SvelteKit, etc) or PHP (Laravel) without hesitation.
However, my absolute favorite backend stack—and the one I find most enjoyable to work with — is what I call the "PRR" stack:
- Ruby (Ruby on Rails): My go-to for rapid product development and complex business logic.
- Python (FastAPI, FastHTML, etc): For robust, high-performance APIs and data-heavy tasks.
- Rust: My choice for performance-critical components and system-level tools (I am actively prioritizing projects involving Rust).
🔥 Whether you are building with my favorite PRR stack, or need an expert to scale and maintain your existing JS/TS or PHP codebase, we are going to be a great fit.
---
2. FRONTEND ARCHITECTURE
While I am completely capable of working with React (it doesn't scare me), I strongly prefer and advocate for simpler, more maintainable frontend architectures:
- Vanilla JavaScript/TypeScript and deep expertise in Web APIs — these are more than enough for most use cases.
- Hypermedia / HTMX / Hotwire: My preferred way to build dynamic, responsive web applications without the overhead of heavy SPA frameworks.
- Elm: For when absolute reliability and zero runtime errors are required on the frontend.
- React/Vue/Svelte - if already integrated in existing code
- Tailwind/Vanilla modern CSS: For rapid, beautiful, and maintainable styling.
---
3. DEVOPS & SYSTEM ADMINISTRATION
DevOps is my parallel specialization. I don't just write code; I know exactly how to deploy, scale, and secure it. I have 12 years of daily Linux administration experience.
- Infrastructure as Code: Terraform, Ansible
- Containers & Orchestration: Docker, Podman, Nomad, Consul (Hashicorp stack)
- Networking & Security: Cloudflare (Zero Trust, Tunnels), Traefik, Nginx, SSL/TLS
- Clouds: AWS, GCP, DigitalOcean, Hetzner, Vercel, Render
