At Convia, we choose technology to serve outcomes: faster delivery, lower total cost, and reliable scale. Below is our curated stack—grouped by capability—with notes on when and why we use each tool.
Tools must improve time-to-value, quality, or cost—prefer proven tech with a roadmap.
OWASP, least privilege, encrypted at rest/in transit, dependency scanning.
Logs, metrics, traces, and clear SLOs from day one.
API-first, modular design, and infrastructure as code for repeatability.
WCAG 2.1 AA targets and measurable performance budgets.
Frameworks: React (Next.js), Vue (Nuxt) for SSR/SSG, Remix for data-driven UX.
Tailwind CSS, Radix UI/shadcn, Material UI; design tokens for brand consistency.
React Query/RTK Query, SWR; GraphQL (Apollo) or REST (OpenAPI).
Fast initial loads (SSR/SSG), strong ecosystem, easy A/B testing and analytics.
Native: Swift/SwiftUI (iOS), Kotlin/Jetpack Compose (Android) for maximum performance and device APIs.
Flutter or React Native for one codebase across iOS and Android.
Firebase (auth, push, analytics), RevenueCat (subscriptions), OneSignal (notifications).
Balance of speed, quality, and maintainability with strong CI/CD and test support.
Engines: Unity (2D/3D/cross-platform), Unreal Engine (high-fidelity 3D), Godot (lightweight 2D).
PlayFab/Photon/Colyseus; custom Node/Go for leaderboards, matchmaking, telemetry.
Blender, Substance, Spine; addressable assets and remote configs.
Mature tools, multi-platform export, robust live-ops support.
Languages/Frameworks: Node.js (NestJS), Python (FastAPI), Go (performance microservices), Java (Spring).
REST (OpenAPI) and GraphQL (Apollo/Federation); gRPC for low-latency services.
OAuth2/OIDC, JWT/opaque tokens, Keycloak/Cognito, fine-grained RBAC/ABAC.
Predictable performance, strong libraries, cloud-native patterns.
Relational: PostgreSQL (primary), MySQL (legacy/interoperability).
Redis, RabbitMQ/Kafka for events and streaming.
BigQuery, Snowflake; dbt for transformations.
Elasticsearch/OpenSearch; Pinecone/Weaviate/FAISS for vector search.
Model Providers: OpenAI, Anthropic, Cohere; on-prem/local LLMs for sensitive data.
LangChain, LlamaIndex for tool-use/RAG; Hugging Face for classic NLP/CV.
Triton/ONNX Runtime, Ray; vector DBs, evaluation harnesses and guardrails.
Fast prototyping, measurable quality, portable deployments.
Chains: Ethereum, Polygon, Arbitrum, Solana (use-case driven).
Solidity, OpenZeppelin, Hardhat/Foundry; audits and testnets as standard.
Next.js frontends, wagmi/ethers.js, WalletConnect/MetaMask, custody options.
Security, liquidity, developer tooling, and user experience maturity.
Commerce Platforms: Shopify/Shopify Plus, WooCommerce, Medusa (headless).
Headless CMS (Contentful/Strapi), Sanity; image CDNs.
Stripe, Adyen, PayPal; Shippo, TaxJar, Klaviyo.
High conversion templates, fast pages, flexible content, global readiness.
Clouds: AWS, GCP, Azure (client preference and regional needs).
Docker, Kubernetes, Helm; serverless (Lambda/Cloud Functions).
Terraform/Pulumi, GitHub Actions, ArgoCD; blue-green/canary releases.
OpenTelemetry, Prometheus/Grafana, ELK; incident runbooks and SLOs.
Pick the fastest path that meets security and scale (e.g., Next.js + headless CMS + Stripe).
Heavy device features → native iOS/Android; broad coverage → Flutter/RN.
Real-time streams → Kafka + ClickHouse; reporting/BI → warehouse + dbt.
Private deployments, key custody, on-prem models where required.
HubSpot, Salesforce, Marketo, Segment
Stripe/Adyen, Apple/Google Pay, Auth0/Keycloak
Twilio/SendGrid/WhatsApp Business; push notifications across platforms
Architecture diagrams, runbooks, API contracts, decision records (ADRs)
SRE checklists, on-call rotations, RPO/RTO targets, cost dashboards
Admin access, playbooks, and workshops so your team can own day-2 operations
