What we do
End-to-end engineering,
from idea to production.
One team across product, web, mobile, backend, AI, and infrastructure — so decisions stay connected and nothing gets lost between handoffs.
Web applications
Fast, accessible front ends backed by well-structured APIs — dashboards, portals, internal tools, and customer-facing apps.
ReactNext.jsTypeScriptASP.NET Core
Mobile app development
Cross-platform and native apps for iOS and Android — designed for touch, connected to your backend, and shipped to the app stores.
React NativeFlutteriOSAndroid
Backend & distributed systems
Services that scale and stay maintainable: clean APIs, background processing, and event-driven integration between systems.

Agentic AI & automation
AI agents and automated workflows that plan, call tools, and act on your data — with guardrails, review steps, and audit trails built in.

Agentic AI
AI agents that do real work — safely.
We design agentic systems that plan, use tools, and take actions across your software, with the guardrails a business needs to trust them in production.
- Grounded in your dataRetrieval over your documents and databases, so answers come from your sources.
- Tools, not just textAgents call your APIs, query systems, and publish events to queues like RabbitMQ.
- Humans stay in controlReview gates for consequential actions, with every step logged and auditable.
- Measured, not guessedEvaluation sets and monitoring to track quality, cost, and latency over time.

We build and ship
our own software.
Our products are where we prove our engineering. Real interfaces, real users, available to try today.
AI CV Builder
Turn experience into a clear, well-presented CV. Draft, switch designs without losing details, and review the result as you write.
- 12 designs with a live resume preview
- Resume scoring and job-description matching
- Import an existing CV or start from scratch
- Export to PDF, Word, HTML, text, Markdown, or JSON
Start editing without an account. AI writing help requires sign-in; downloads require a verified email.
Excel AI Studio
Clean up messy spreadsheets with an AI assistant that shows its work. Describe a problem, review proposed cell changes, and apply only what you agree with.
- Open Excel and CSV files in a spreadsheet grid
- Fix text-based numbers, dates, and inconsistent values
- Preview every change, with full undo history
- Export Excel, CSV, or structured JSON
In public beta. The workspace requires sign-in; original formatting is preserved.

Engineering standards
Built the way
serious software is built.
Industry-standard practice on every engagement, whether it’s our own product or yours.
Architecture first
We agree on boundaries, data models, and integration points before writing features, so the system can grow without rewrites.
Code review on every change
Pull requests, consistent conventions, and readable code — software another engineer can pick up and extend.
Automated testing
Unit and integration tests around business logic and APIs, run automatically before anything is released.
CI/CD from day one
Every commit is built and validated by a pipeline. Deployments are scripted, repeatable, and verifiable.
Secure by default
Least-privilege access, secrets kept out of code, validated input, and dependencies kept up to date.
Documentation & handover
Architecture notes, setup guides, and runbooks, so your team owns the software — not just the binaries.
How we work
A clear path
from brief to release.
Short feedback loops and working software at every stage, so you always know where the project stands.
Discover
Goals, users, constraints, and how the work happens today.
Design
User flows, interface design, data models, and a prioritised plan.
Build & iterate
Incremental delivery with regular demos, reviews, and testing.
Launch & evolve
Production rollout, monitoring, handover, and the next improvements.
Ways to work together
An engagement that fits your stage.
Whether you’re validating an idea or extending an existing platform, we shape the engagement around what you need next.

Talk to our engineersWhat kind of projects do you take on?
Web applications, mobile apps for iOS and Android, SaaS products, internal business tools, APIs and backend services, system integrations, workflow automation, and AI or agentic features. Share the problem, the intended users, and any timeline or budget constraints so we can propose a suitable scope.
Which technologies do you work with?
Our core stack covers React, Next.js and TypeScript on the frontend; React Native and Flutter for mobile; ASP.NET Core / C# and Python on the backend; RabbitMQ for messaging; SQL and NoSQL databases; and Docker, GitHub Actions, Linux and NGINX for delivery. We also integrate LLM APIs to build AI agents and retrieval-based features.
How do you approach agentic AI safely?
We scope agents to clear tasks, give them access only to the tools they need, add human review for consequential actions, and log every step. We evaluate quality against real examples before and after launch.
Can I try your products today?
Yes. AI CV Builder is live and Excel AI Studio is in public beta. PostTrick and AI Video Player are in development.
Do you use AI in your own development?
Yes. We use Claude as a development assistant. Within our products, AI is used for specific tasks such as writing assistance or data transformations, and users review the results.
How do we get started?
Email admin@elfasyssolution.com with a short description of what you want to build or improve. We’ll arrange a call to understand your goals and suggest a practical first step.
