Spar Tech Labs

Comprehensive Technical Solutions.

We build and modernize real production systems — the kind that stay fast under load, stay predictable during growth, and stay maintainable long after launch. Whether you need a new SaaS product, an internal tool, an AI workflow, or a hardened kiosk environment, we ship clean, documented work with clear ownership and measurable outcomes.

Digital Engineering

Customer-facing products and internal systems built with performance budgets, clean architecture, and a delivery cadence you can trust.

Enterprise Web Platforms

  • Next.js apps built for Core Web Vitals, SEO, and long-term maintainability
  • SaaS dashboards, admin panels, and role-based access control (RBAC)
  • Design system + component libraries for consistent UI at scale
  • Integrations: payments, analytics, auth providers, CMS, and third-party APIs
  • Observability-ready builds: structured logs, metrics, and error tracking

Mobile Application Development

  • React Native apps with clean state management and production-grade architecture
  • Progressive Web Apps (PWA) optimized for fast startup and offline-friendly flows
  • Native iOS/Android performance fixes (startup time, memory, animations)
  • Release engineering: CI builds, signing, store submissions, staged rollouts
  • Analytics + crash reporting to see what users actually experience

Custom Software Solutions

  • Internal tools that reduce manual work and eliminate spreadsheet chaos
  • Legacy system modernization (rewrite, strangler pattern, or incremental refactor)
  • API design: REST/GraphQL, versioning strategy, pagination, rate limits
  • Database architecture: schema design, indexing, migrations, and backups
  • Performance tuning: slow queries, caching, and bottleneck removal

AI & Intelligence

Practical AI that’s measurable in production: grounded outputs, evaluation gates, and workflows that don’t break the moment the prompt changes.

LLM Training & Fine-Tuning

  • Custom chat assistants trained on your docs, tickets, and knowledge base
  • RAG pipelines with chunking, retrieval tuning, and source citations
  • Open-source model hosting (Llama/Mistral) with GPU + cost controls
  • Prompt + tool design that reduces hallucinations and increases reliability
  • Evaluation harness: golden sets, regression checks, and quality metrics

Process Automation

  • Workflow automation using n8n/Zapier (or custom) with audit trails
  • Scrapers/crawlers with retries, dedupe, and anti-breakage design
  • Automated reporting that pulls from DBs/APIs and delivers on schedule
  • Ops automation: alerts → runbooks → remediation helpers
  • Human-in-the-loop pipelines for approvals where it matters

AI Consulting

  • Feasibility studies: where AI helps vs where it adds risk
  • Roadmaps: data readiness, tooling, infra, and deployment approach
  • Vendor/model selection: tradeoffs between hosted vs self-hosted
  • Performance & cost tuning: latency, throughput, token spend
  • Security posture: data handling, access control, and redaction strategy

Hardware & Embedded Systems

Reliable deployments in the real world: locked-down environments, offline-first setups, remote observability, and secure update paths.

Kiosk Setup & Software

  • Interactive touch kiosks built for stability and simple user flows
  • Device lockdown (kiosk mode), safe browsing, and tamper resistance
  • Digital signage orchestration with schedules and content rotation
  • Payment terminal / peripheral integration (printers, scanners, readers)
  • Offline-first flows for unreliable network environments

IoT Solutions

  • Raspberry Pi / Jetson builds with hardware drivers and service orchestration
  • Sensor ingestion pipelines with buffering, retries, and data validation
  • Remote device management: monitoring, logs, updates, and fleet status
  • Edge compute: inference on device + upload of compact events
  • Security: keys, provisioning, and least-privilege system design

System Administration

  • Linux server hardening, patching strategy, and baseline configurations
  • Docker/Kubernetes setup with sane defaults and repeatable deployments
  • Cloud builds across AWS/GCP/Vercel with cost + reliability guardrails
  • CI/CD pipelines with staging environments and safe rollout patterns
  • Security audits: permissions, secrets, dependency risk, and fixes

Not sure where to start?

If you’re deciding between a rewrite vs. improvements, choosing a stack, or planning how to scale without breaking things — we can help. In a short call, we’ll map your goals, identify risks, and suggest the most practical path forward (including what not to build).

Clear scope. Clear timeline. No pressure.
