Frequently Asked Questions

I specialize in PHP/Laravel for backend, React/Next.js for frontend, PostgreSQL and MySQL for databases, Docker and Kubernetes for DevOps, and AWS/GCP for cloud infrastructure.

Yes, I work remotely with clients worldwide. I am based in Temerin, Serbia (CET timezone) and can adapt to your timezone for meetings.

Project timelines depend on complexity. A simple API integration can take 1-2 weeks, while a full SaaS platform typically takes 3-6 months. I always provide a detailed estimate after an initial discovery session.

Yes, I offer retainer-based maintenance packages. This includes monitoring, security updates, performance optimization and feature additions. Packages start from 10 hours/month.

Yes. I have hands-on experience integrating OpenAI, Anthropic Claude and Google Gemini APIs into production systems. This includes chat interfaces, RAG pipelines for document Q&A, semantic search, automated content generation and AI agents. I handle prompt engineering, rate limiting, cost controls and fallback strategies so the feature is production-safe from day one.

It usually starts with an infrastructure audit: cluster configuration, resource requests/limits, network policies, RBAC and monitoring coverage. From there I deliver a prioritized remediation plan covering security hardening, autoscaling policies, CI/CD pipeline integration and observability. Most engagements run 4-8 weeks for an initial setup or 1-2 weeks for an audit-only scope.

I work with both. For early-stage startups I focus on delivering an MVP quickly with a clean architecture that can grow — avoiding tech debt traps that slow teams down later. For established companies I bring depth in refactoring, performance scaling, and introducing modern tooling without disrupting running systems.

Vibe Rescue is designed for founders and teams who used AI coding tools (Cursor, Lovable, Bolt, v0, GitHub Copilot) to build a prototype that now needs to be production-ready. I audit the codebase, fix architectural problems, add authentication, tests, CI/CD and proper error handling — turning a fragile AI-generated prototype into a maintainable, deployable product.

I use async-first communication via Slack or email with structured weekly status updates. For active sprints I join daily standups or short sync calls as needed. All work is tracked in the project management tool of your choice (Linear, Jira, Notion) with clear task breakdowns, acceptance criteria and delivery estimates updated in real time.

Yes, but I always start with the question of whether microservices are actually the right solution. For teams under 20 engineers, a well-structured modular monolith often outperforms a distributed system in delivery speed and operational cost. When the split is justified, I use the strangler fig pattern: incrementally extract bounded contexts behind stable API contracts, keeping the monolith runnable throughout.

Security is built in from the start, not bolted on. I follow OWASP guidelines, enforce least-privilege access, validate and sanitize all input at the boundary, use parameterized queries, store secrets in environment variables or vaults, and implement proper authentication with short-lived tokens. For sensitive projects I include a dedicated security review before launch.

Yes. I write unit tests for business logic, integration tests for API endpoints and service boundaries, and smoke tests for critical user paths. Test coverage targets are agreed per project — I do not write tests for the sake of a number, but to protect the most critical and change-prone paths. For Laravel projects I use Pest, for React I use Vitest and Testing Library.

I offer both fixed-price project packages and hourly/daily rate engagements. Fixed-price packages work well for clearly scoped projects. For ongoing work, advisory roles or evolving requirements, a monthly retainer or time-and-materials arrangement fits better. Pricing depends on scope, timeline and tech complexity — I always provide a written estimate before starting.

Yes. I start with a codebase audit to map the architecture, identify risks and document what exists. Then I create a transition plan that keeps the product running while I get up to speed. I have taken over Laravel APIs, Next.js frontends and full-stack projects at various stages — from greenfield hand-offs to legacy rescues.

I have built and scaled multi-tenant platforms using both shared-database and database-per-tenant strategies in Laravel. Key areas I cover include tenant isolation, data residency compliance, per-tenant feature flags, subscription billing with Stripe, onboarding flows and white-labeling. I help choose the right tenancy model based on your compliance needs and expected scale.

Yes. Advisory-only engagements are a significant part of my work. This includes one-time architecture reviews with a written findings report, ongoing fractional CTO support, team code reviews, technical due diligence for investors or acquirers, and structured mentoring for engineering leads. These engagements typically run from a few hours to a few days per month.
