Kharvex · Engineering, prototyping & component supply

Services

Two businesses, one bench

R&D services for constrained, production-bound devices — and a verified supply line for the components they run on. Engage us as plug-in engineers for your team, on a fixed-price prototype, or end to end from audit to production.

01 — Engineering & Design

Design services

Models, firmware and architecture engineered for constrained, production-bound devices.

Edge AI & Model Development

Custom models engineered for constrained devices — trained, quantized and validated against production data. Deliverables: trained weights, quantization report, evaluation suite. Tooling: PyTorch, ONNX, TensorRT, TVM.

Inference Optimization & Deployment

Latency and power budgets honored; deployment validated under production thermals. Deliverables: optimized runtime, fleet rollout plan, rollback path. Tooling: TensorRT, ONNX Runtime, edge runtimes, thermal-aware benchmarking.

DevOps & MLOps Engineering

Reproducible pipelines and sane infrastructure. Deliverables: pipeline source, runbooks, monitoring setup. Tooling: Kubernetes, Terraform, CI/CD, MLflow.

Engineering Consulting

Senior review of architectures, BOMs and roadmaps. Deliverables: written opinion, risk register, prioritized roadmap. Tooling-agnostic — the output is the decision quality.

02 — NPI & Prototype Support

From design to manufacturable

DFM feedback, BOM validation, testing and certification preparation — with qualified manufacturing partners.

CAD & Mechanical Design

Enclosures, thermal and mounting design. Deliverables: STEP/DWG files, 2D drawings — fabricator-ready without follow-up calls. Tooling: KiCad/Altium schematic & layout, mechanical CAD exports.

Prototyping

Boards, firmware and enclosures iterated in tight loops. Deliverables: working artifact, BOM, gerbers, firmware source. Tooling: STM32/ESP32, Zephyr/FreeRTOS, instrumented bench.

NPI & DFM Support

New Product Introduction support: design-for-manufacturability feedback (stack-up, clearances, panelization), BOM validation against availability, and prototype-to-pilot coordination with audited, qualified manufacturing partners.

Testing & Validation

Board bring-up, design validation and functional test plans — thermal, power and signal verification before you commit to volume. Deliverables: validation report, test procedures, issue register.

Certification Support

CE/FCC/Bluetooth qualification document preparation and EMC pre-compliance planning. Deliverables: pre-compliance checklist, documentation package, test-lab coordination.

03 — Sourcing & Supply Chain

Components, logistics, continuity

From single samples to production volumes — including the hard-to-find and the obsolete.

Component Sourcing & Trading

Industrial electronic parts, embedded devices and hardware sourced and traded under export code 451613 — including hard-to-find and obsolete components through a vetted supplier network. Deliverables: verified supply, supporting documentation.

Logistics & Incoterms

EXW, FOB and CIF arrangements agreed per order; lead times quoted at RFQ. Samples policy: evaluation units shipped before volume commitment.

Compliance & Traceability

Parts verification with a counterfeit-mitigation process: provenance checks and RoHS/REACH documentation on every sourced line. Banking and customs paperwork handled end to end.

EOL & Obsolescence Support

Sourcing continuity for end-of-life and discontinued components, including last-time-buy coordination before parts disappear.

Cost-Savings & Alternative-Part Programs

Qualified alternative parts and dual-sourcing options reviewed for fit, availability and compliance — with documented rationale for every change.

04 — Sustaining & After-Launch

The half that keeps products alive

Firmware maintenance, supply continuity and replenishment after your product ships.

Firmware & Software Maintenance

Post-launch updates, security patches and board-revision support. Deliverables: change records, release notes, regression results.

Supply & Replenishment

Re-order handling, lead-time management and component replacement when parts change or go end-of-life.

Obsolescence Planning

Forward-looking EOL visibility and migration recommendations — planned before components disappear, not after.

How we work

Engagement model & process

Three ways to engage

Plug-in engineers for your team, a fixed-price prototype engagement, or audit-to-production support. A dedicated project manager is your single point of contact in every mode — an extension of your team, not a vendor behind a ticket queue.

01 · Requirements

We help write or review your requirements — a well-written spec is the cheapest risk reduction available.

02 · Estimate

Fixed-price proposal with frozen scope; deliverables, stage gates and IP terms defined in writing.

03 · Weekly plan-vs-actual

Transparent progress: weekly reporting against schedule and budget, with risks surfaced in writing — not in meetings.

04 · Validation & sign-off

The working artifact is demonstrated against the agreed requirements before transfer.

05 · Artifact transfer

Sources, drawings, models and documentation transferred at final payment. You own everything.

Where we work

Typical domains

Scope statements, not claims — the industries and buyers our services are built for.

Industrial automation

Controllers, gateways and instrumentation for factory and process environments.

IoT & edge devices

Connected products, sensors and gateways with real deployment constraints.

Laboratories & test equipment

Instrumentation and data-acquisition hardware built for repeatable measurement.

Export buyers & integrators

Embedded hardware sourced to spec and documented for customs — quantities from samples to volumes.
