Fish Commander
A rod-mounted sensor that reads line tension, line length and angle — and streams true hook depth to a phone.
Most products die between the sketch and the tool. Ours do not. Efficio Engineering is a multidisciplinary company — mechanical, electronics, firmware, simulation and manufacturing under one roof — so nothing gets lost in a handover. Over 100 products delivered for founders and manufacturers worldwide.
No mood boards, no stock renders. Open any card and you get the brief that came in, what we engineered, the numbers we hit, and the files that went out. Two minutes each.

Three ways in, one team behind all of them. Open a solution to see exactly what it covers — and the delivered work that proves it.
We take a product from a brief or a sketch through industrial design, mechanical engineering, prototyping and DFM to a manufacturable design package.
Schematic capture, multi-layer rigid and flex PCB layout, and the embedded firmware that runs on the board — designed together rather than handed between vendors.
Structural, thermal, flow and vibration studies in ANSYS — used to size parts, prove compliance against a standard, and settle design arguments with numbers instead of opinions.
Efficio Engineering is a product development company in Rawalpindi, Pakistan, with a multidisciplinary team in-house — mechanical, electrical, mechatronics and aerospace engineers, working the same product at the same time. Hire one of us and you get all of us: the engineer who models the part sits with the one who routes the board and the one who signs off the tool. That is why our designs survive contact with a factory.
3D modelling, mechanism and enclosure design, tolerance analysis and GD&T production drawings.
Schematic capture, multi-layer rigid and flex PCB layout, power, sensing and release files.
Embedded firmware, motor and actuator control, BLE and Wi-Fi connectivity, companion apps.
Aerodynamic and structural studies, lightweight design, and analysis written against the governing standard.
Industrial design, materials and finish selection, cost engineering, supplier management — whatever the product turns out to need.
FEA, CFD, thermal and vibration studies in ANSYS — used to size parts and prove compliance.
Printed, machined and assembled in-house, then taken through DFM, tooling and production handoff.
Efficio is led by engineers who stay close to the work, from the first client conversation through design verification, prototyping and production handoff.


Design in the morning, part in your hand by evening. Our own print and machining floor in Rawalpindi means a revision costs hours, not a two-week quote cycle — so designs get tested before a tool is ever cut.
01Fast, functional prototypes for full-size enclosures, mechanisms, fixtures and assembly checks, supporting multiple design revisions before tooling.
02High-detail parts for thin walls, fine features, threads, light guides, cosmetic models and precise fit validation where standard FDM resolution is not enough.
03Rapid cutting of flat profiles, templates, panels and prototype assemblies for quick dimensional checks before committing to production tooling.
04Production-aware brackets, covers and chassis developed with realistic bend radii, fastener access, clearances and assembly sequence in mind.
05Machined plates, brackets and fixtures are supported by soldering, rework, bench power, oscilloscope and logic analysis for complete electromechanical bring-up.
Every number below sits on Upwork, where the client writes the review and we cannot edit it. Read the feedback, check the contract history, or message us straight from either profile — both are open to clients.
Milestone-based fixed pricing when the scope is well defined, hourly when the work needs iteration. You know which one you are buying before we start.
Native CAD, drawings, PCB source and firmware are handed over as agreed at the start. Deliverables, revisions and exclusions are written down, not assumed.
Based in Rawalpindi, Pakistan, working with clients across the US, Europe and Australia, on a shift that overlaps Western mornings.
Tooling design, GD&T drawings, supplier engagement and first-article support — the work above includes products that shipped.
