Capability Portfolio
Engineering services that ship measurable outcomes
From cloud-native platforms to applied AI and connected hardware — Sijenius delivers end-to-end engineering for teams that need to move from concept to production with discipline and speed.
01 — Capabilities
Six practice areas, one engineering standard
Every engagement is staffed by senior practitioners and backed by a delivery framework tuned for observability, security, and predictable velocity.
Applied AI & Machine Learning
LLM integration, RAG systems, model evaluation pipelines, and MLops. Production deployments with guardrails, observability, and measurable ROI from day one.
See AI deploymentsProduct & Experience Design
Research-driven product strategy, design systems, and high-fidelity prototyping. We design for accessibility, performance, and the constraints real users operate within.
Browse case studiesData & Analytics Engineering
Modern data stacks, real-time pipelines, and governed lakehouses. We architect for lineage, quality, and the analytics workloads your business actually runs.
Data architectureIoT & Connected Hardware
Firmware, edge compute, and device-to-cloud pipelines. Secure provisioning, OTA updates, and fleet management for industrial sensors, consumer devices, and telematics.
Talk to an engineerSecurity & Compliance
SOC 2, ISO 27001, HIPAA, and PCI readiness. Threat modeling, zero-trust architecture, and continuous control monitoring — built into delivery, not bolted on after.
Security services
02 — Process
A delivery model tuned for compound velocity
Four phases that compress decision latency, surface risk early, and hand off production systems your team can operate long after we leave.
01
Discover & Frame
Two-week diagnostic. Stakeholder interviews, technical audit, and a quantified business case with explicit success criteria.
Week 1–202
Architect & Prototype
Reference architecture, risk-ranked roadmap, and a working prototype that validates the hardest assumptions before scale-out.
Week 3–603
Build & Harden
Squad-based delivery with continuous integration, observability, and security gates. Demo every Friday, ship every two weeks.
Week 7–N04
Transfer & Scale
Runbooks, training, and a 90-day hypercare window. Knowledge transfer measured by ticket deflection, not slide decks.
Launch + 90d
03 — Technology Stack
Tool-agnostic, opinionated where it counts
We select tools based on team maturity, workload shape, and total cost — not on what is trending. Below is the shortlist we reach for most often; if your stack isn't listed, we will learn it.
Kubernetes & Istio
Terraform & Pulumi
Python / Go / TypeScript
PostgreSQL & ClickHouse
OpenAI / Anthropic / OSS
Datadog / Grafana / OpenTelemetry
React / Next.js / Swift / Kotlin
Rust / Embedded Linux / Zephyr
04 — Engagement Models
Choose the shape that fits the problem
All engagements share the same engineering standards, code ownership terms, and delivery cadence. What changes is scope, duration, and the level of cross-team integration.
Sprint
2–6 weeks · Fixed scope
Targeted outcomes for a defined problem: a prototype, a migration spike, a security audit, or an architecture review with implementation runway.
- Defined deliverable & acceptance criteria
- Senior engineer + specialist
- Weekly demo, fixed price
Dedicated Squad
3–18 months · Time & materials
A cross-functional squad embedded with your team — product, design, engineering, and QA — owning a roadmap end-to-end with shared KPIs.
- 4–8 engineers, full product squad
- Shared backlog, your tooling
- Monthly capacity & outcome review
- Code & IP transfers on exit
Managed Service
12+ months · Outcome-based
We own and operate a production system on your behalf — platform, data, or applied AI — against agreed SLAs and a continuous improvement backlog.
- Defined SLAs & on-call coverage
- Quarterly business reviews
- Optional buy-back clause
05 — Client voice
What partnering with Sijenius looks like in practice
Sijenius replaced three vendors and a six-month roadmap with a working platform in nine weeks. Their platform team taught ours how to operate what they built, which is the part most firms skip.
