Core Engineering Domains & Stack Hierarchy
Explore how we structure our technological competencies into distinct domain tiers for enterprise clients worldwide.
Full-Stack Reactive & Edge (MERN, MEAN & Next.js 15)
Modern interactive single-page applications, React Server Components (RSC), and Angular 18 Signals engineered for sub-second page loads and seamless cloud distribution.
Enterprise Backend & SaaS (Laravel 11 & Core PHP)
High-concurrency business platforms, multi-tenant ERPs, and financial ledgers powered by Laravel Octane, JIT compilation, and native WebSockets.
High-Throughput Microservices (Java Spring Boot & NestJS)
Distributed microservice meshes built on Java 21 Virtual Threads and NestJS modular architectures with Kafka event streaming and circuit breakers.
Agentic AI, RAG & LangGraph Systems
Autonomous multi-agent swarms, cyclical state graphs, hybrid vector search (Qdrant), and production LLM inference pipelines with audit-proof verification.
Sovereign Knowledge Wikis & Enterprise WordPress
Decoupled headless WordPress with Next.js frontends and Git-synchronized Open Source Wiki engines (Wiki.js, BookStack) for compliance and documentation.
MariaDB Galera Clusters & Cloud DevOps
Multi-master synchronous relational clusters, ProxySQL read-write splitting, Kubernetes container orchestration, and automated Terraform infrastructure.

PHP with Laravel 11 Ecosystem
Enterprise SaaS, High-Concurrency Web Applications & Event-Driven Systems
Sibiri Innovation treats Laravel 11 as a premier enterprise engineering platform. We leverage Laravel Octane (FrankenPHP/Swoole), Horizon background workers, Livewire, and Redis clustering to deliver robust multi-tenant architectures, financial ledgers, and distributed systems handling millions of daily requests with mathematical reliability.
Architectural Highlights & Standards
- High-concurrency in-memory execution using Laravel Octane with persistent application state.
- Decoupled Service-Repository architecture with strict domain-driven design (DDD) boundaries.
- Real-time WebSocket event broadcasting with Laravel Reverb, eliminating third-party subscription fees.
- Enterprise queue management with Redis clustering, automatic failure dead-letter queues, and Horizon metrics.
- Granular role-based permissions (Spatie), OAuth2 token authentication, and comprehensive audit logs.
<?php
namespace App\Services;
use App\Repositories\Contracts\OrderRepositoryInterface;
use App\Events\OrderProcessed;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Cache;
class EnterpriseOrderService
{
public function __construct(protected OrderRepositoryInterface $orders) {}
public function processOrder(array $payload): Order
{
return DB::transaction(function () use ($payload) {
$order = $this->orders->createWithLock($payload);
Cache::tags(['analytics', 'financials'])->flush();
event(new OrderProcessed($order));
return $order;
}, attempts: 5);
}
}
Modern Core PHP (PHP 8.3+)
High-Throughput Micro-Engines, Custom Composer Packages & Standalone Daemons
Beyond full frameworks, our engineering teams build specialized, ultra-lightweight micro-services and custom Composer packages using modern PHP 8.3+. Taking full advantage of JIT (Just-In-Time) compilation, strict typed properties, Readonly classes, and Fibers for asynchronous I/O, we achieve raw execution speeds competitive with Go and Java.
Architectural Highlights & Standards
- Strict typing standards (declare(strict_types=1)) with 100% PHPStan Level 9 static analysis.
- JIT compilation configured for CPU-bound computations, complex mathematics, and parsing.
- Lightweight, framework-free micro-services complying with PSR-7 (HTTP Messages) and PSR-15 (Handlers).
- Non-blocking asynchronous concurrency using native PHP Fibers and event loop runtimes.
- Zero-dependency standalone Composer libraries designed for enterprise reusability across platforms.
<?php
declare(strict_types=1);
namespace Sibiri\Core\Engine;
readonly class TransactionPayload
{
public function __construct(
public string $transactionId,
public float $amount,
public string $currency,
public \DateTimeImmutable $timestamp
) {}
public function validate(): bool
{
return $this->amount > 0 && strlen($this->currency) === 3;
}
}
Python with Django & FastAPI
Asynchronous REST/GraphQL APIs, Data Pipelines & Rapid AI Microservice Integration
Our Python practice bridges modern web engineering with machine learning and computational workflows. We deploy Django 5 for batteries-included administrative platforms, and FastAPI for high-throughput asynchronous microservices, data ingestion engines, and low-latency AI inference gateways.
Architectural Highlights & Standards
- High-throughput ASGI asynchronous request processing with Uvicorn and Pydantic v2 validation.
- Battle-tested Django ORM with declarative migrations, automated admin tooling, and connection pooling.
- Distributed background task queuing and cron scheduling via Celery and Redis/RabbitMQ.
- Native zero-copy serialization between Python AI libraries (PyTorch, Pandas) and API consumers.
- Comprehensive OpenAPI / Swagger specification auto-generated from typed schema annotations.
# FastAPI Asynchronous Microservice Endpoint with Pydantic v2
from fastapi import FastAPI, BackgroundTasks, Depends, HTTPException
from pydantic import BaseModel, Field
import uvicorn
app = FastAPI(title="Sibiri Inference API", version="2.4.0")
class InferenceRequest(BaseModel):
document_id: str
query: str = Field(..., min_length=3)
temperature: float = Field(default=0.2, ge=0.0, le=1.0)
@app.post("/api/v1/predict")
async def generate_prediction(req: InferenceRequest, bg: BackgroundTasks):
# Asynchronous non-blocking AI pipeline
bg.add_task(log_telemetry_async, req.document_id)
result = await execute_rag_pipeline(req.document_id, req.query, req.temperature)
return {"status": "success", "payload": result}
