01Reach us
+
+
Email is the front door: inquiry@phasefinal.com. A sentence about the problem and the date it needs to exist by is a complete first message.
+
+
What happens next
A reply from the engineer who would own the work, usually within one business day, either with questions that sharpen the scope or with a proposed call.
+
What we need to quote
The spec (or the rough shape of it), the deadline, any constraints already fixed — platforms, vendors, compliance regimes — and who signs.

Company details

Engagements are fixed-bid or retainer, chosen by the shape of the work rather than by preference. Most new work arrives by referral.

01Engagement models
+
+
+
+
Fixed-bid
+
Where the scope can be specified: a defined deliverable at a defined price, with written requirements and acceptance criteria before work starts. Change requests move scope, not the deadline's meaning.
+
+
+
Retainer
+
Where the work is continuous: operation, maintenance, and engineering capacity over time. A named owner, a standing review cadence, and a queue the client controls.
+
+
+
+
+
+
+
02How an engagement runs
+
+
+
1. Spec and constraints
You send the spec and the deadline. We send back what it takes to reach the final phase — including the parts of the spec that turn out to be in tension with the deadline.
+
2. Written plan
Requirements, acceptance criteria, and milestones on paper before code. On a fixed bid, this document is the contract's second half.
+
3. Build in the open
Regular demos against real environments, not mockups. Problems surface during the build, at build-time prices.
+
4. Handover or operate
Documentation, runbooks, and a clean handover — or we keep operating it under retainer. Both are first-class outcomes.
Native mobile, web, and desktop applications built to the client's spec — designed, shipped, and operated by the same team. iOS, Android, backend services, and the release pipeline behind them.
Design and integration of complete systems, hardware and software. Requirements, architecture, implementation, and verification are treated as one problem with one owner.
Engineering and operation of AI systems. Model-backed capability is built, integrated, and run as production software, held to the same standard as everything else the firm ships.

What this site collects
Nothing from your browser. Fonts and images are served from this site itself. No advertising or analytics scripts are loaded, so no cross-site profiling occurs on our side.
+
What email you send us
Inquiries sent to inquiry@phasefinal.com are retained as ordinary business email for correspondence and engagement records. We do not add you to marketing lists; there are no marketing lists.
+
Hosting
This site is served from infrastructure the firm operates, fronted by Cloudflare for TLS and caching. Server logs exist for abuse control and are not joined to anything else.
Model-backed capability, run as production software.
+
AI systems get built, integrated, and operated here the same way everything else does — with requirements, verification, and an owner — rather than as a demo that quietly rots.
+
+
+
+
+
+
+
+
+
+
01What we do
+
+
A model call is easy. An AI system — with latency budgets, evaluation suites, fallbacks, cost ceilings, and an upgrade story — is engineering. That part is no different from any other discipline the firm practices.
+
+
+
Retrieval and context pipelines
+
Embedding and reranking services, chunking strategy, and evaluation harnesses, so answer quality is measured rather than sampled by vibes.
+
+
+
Model serving and gateways
+
Open-weight serving on owned GPUs, API gateways with per-team budgets and full request logging, and routing policies that survive a provider outage.
+
+
+
Agents and workflow automation
+
Model-backed automation wired into real operational systems — tickets, documents, messaging — with typed decisions where a decision is all you need.
+
+
+
Evaluation and calibration
+
Task-specific eval suites and threshold calibration against client data, so a model swap is a decision, not an incident.
Hosting and operation of client infrastructure. Systems the firm builds can run on infrastructure the firm operates, under the same accountability as the build.
+
+
+
+
+
+
+
+
+
+
01What we operate
+
+
The firm runs its own multi-site production infrastructure — colocated servers, virtualization, private networking, backup, and monitoring — and has for years. That is not a brochure claim; it is the same infrastructure that runs the tools this site's owners depend on daily.
+
+
+
Colocation and private cloud
+
Dedicated hardware in carrier facilities, virtualized and network-partitioned per client. Predictable cost at scale, no surprise egress line items.
+
+
+
Backup and recovery architecture
+
Two-site backup with independent failure domains, tested restores. A backup nobody has restored from is a rumor.
+
+
+
Monitoring and response
+
Fleet monitoring, alerting, and on-call handling. Systems are observed, not hoped for.
+
+
+
Application operations
+
Hosting for client applications the firm did not write, under the same standards: monitoring, patching, and a named owner.
We design, build, and operate applications: native iOS and Android, web and desktop clients, the backend services behind them, and the release pipeline that keeps them shipping. The team that builds an app stays accountable for it in production — no hand-off cliff.
+
+
+
+
+
+
+
+
+
+
01Scope
+
+
An application is never just the app. It is the client binary, the API behind it, the data model, the release train, and the operational story for what happens at 2 a.m. when something breaks. We take the whole problem.
+
+
+
Native mobile (iOS & Android)
+
Native and cross-platform mobile applications, from first submission through App Store and Play submission, staged rollouts, and OTA updates. Device integration when the app talks to hardware the firm also designed.
+
+
+
Web and desktop applications
+
Internal tools, operator consoles, customer portals, and desktop utilities. Chosen for the job rather than for fashion — plain served HTML is a legitimate architecture.
+
+
+
Backend and APIs
+
Service design, data modeling, authentication, and integration with the systems a client already runs. Documented interfaces and versioned contracts so the application and its backend can move independently.
+
+
+
Release engineering
+
Build pipelines, signing, provisioning, store review handling, crash reporting, and telemetry. An app without a release pipeline is a prototype.
+
+
+
Operation and maintenance
+
Post-launch retainers cover OS-compatibility updates, store policy changes, dependency upkeep, and capacity. Applications decay quietly when nobody owns them; we keep the ownership explicit.
Requirements, architecture, implementation, and verification are treated as one problem with one owner. That is the difference between systems engineering and a chain of hand-offs.
+
+
+
+
+
+
+
+
+
+
01Method
+
+
Most engineering failures between disciplines happen in the seams: firmware blames the app, the app blames the API, the API blames the infrastructure. Systems engineering is the discipline of refusing those seams — one accountable owner across the stack.
+
+
+
Requirements and constraints
+
Written down, ranked, and testable before anybody builds. A requirement you cannot verify is a wish.
+
+
+
Architecture
+
Partitioning hardware, firmware, software, and infrastructure so each piece can fail, ship, and evolve in the way that is actually cheap.
+
+
+
Implementation
+
Firmware, applications, services, and infrastructure built by the same team that drew the boxes, so the drawing stays honest.
+
+
+
Verification
+
Every requirement traced to a test that can fail. Field data feeds the next revision rather than the next excuse.
A long track record in hardware, firmware, and software engineering across an unusually wide range of industries — each of them taught us something we now sell as an assumption.
