I would not completely exclude big tech. Hold a cap weighted index as the core position. Soften the tech concentration with value tilts.

For the US stock sleeve of your portfolio you might try

    75% VTI  #core position. cap weighted total US market
    10% AVLV #tilt large cap value
    15% AVUV #tilt small cap value

Don't forget international. A good way reduce your big tech allocations

    80% VEA  #intl developed
    20% VEXC #intl emerging, ex-China

    VTI 45
    AVLV 6
    AVUV 9
    VEA 32
    VEXC 8
